Open local index.html with URL parameters using system() - r

I want to launch a local website from R (in linux) using system(), but I need to pass a parameter, so I need the "URL" to be something like /home/myuser/index.html?q=1.
When I launch it the "?" becomes "%3F":
system('google-chrome /home/myuser/index.html?q=1')
file:///home/myuser/index.html%3Fq=1
But this conversion does not happen when launching a website:
system('google-chrome https://www.google.com/search?q=hello')
https://www.google.com/search?q=hello
So, how can I make system('google-chrome /home/myuser/index.html?q=1') go to: file:///home/myuser/index.html?q=1?
Thanks!

SQL Server Management Studio will not redirect output from command line

I am using SQL Server Agent to run a few scripts regularly of type CmdExec with the following format:
"Absolute path to RScript.exe" "Absolute path to script.R" > "Absolute path to log folder\logfilename.txt"
This line will work when used manually in the command prompt but won't create a log file when executed through SSMS. Anyone else have trouble dealing with SSMS or is there a problem with my line?
What also works (in the sense that a file is created) in SSMS is type nul > "Absolute path to log folder\logfilename.txt" so there is no problem with the file path or write permissions.
Not sure if this piping is possible for "normal" commands, but under Step Properties -> Advanced, you can choose to save output to file

Installing an MSP using Powershell works on the local machine, fails remotely. Why?

I need some Powershell advice.
I need to install an application's MSP update file on multiple Win08r2 servers. If I run these commands locally, within the target machine's PS window, it does exactly what I want it to:
$command = 'msiexec.exe /p "c:\test\My Application Update 01.msp" REBOOTPROMPT=S /qb!'
invoke-wmimethod -path win32_process -name create -argumentlist $command
The file being executed is located on the target machine
If I remotely connect to the machine, and execute the two commands, it opens two x64 msiexec.exe process, and one msiexec.exe *32 process, and just sits there.
If I restart the server, it doesn't show that the update was installed, so I don't think it's a timing thing.
I've tried creating and remotely executing a PS1 file with the two lines, but that seems to do the same thing.
If anyone has advice on getting my MSP update installed remotely, I'd be all ears.
I think I've included all the information I have, but if something is missing, please ask questions, and I'll fill in any blanks.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
My process for this is:
Read a CSV for server name and Administrator password
Create a credential with the password
Create a new session using the machine name and credential
Create a temporary folder to hold my update MSP file
Call a PS1 file that downloads the update file to the target server
>>> Creates a new System.Net.WebClient object
>>> Uses that web client object to download from the source to the location on the target server
Call another PS1 file that applies the patch that was just downloaded –>> This is where I’m having issues.
>>> Set the variable shown above
>>> Execute the file specified in the variable
Close the session to the target server
Move to the next server in the CSV…
If I open a PS window and manually set the variable, then execute it (as shown above in the two lines of code), it works fine. If I create a PS1 file on the target server, containing the same two lines of code, then right click > ‘Run With PowerShell’ it works as expected / desired. If I remotely execute my code in PowerGUI, it returns a block of text that looks like this, then just sits there. RDP’d into the server, the installer never launches. My understanding of the “Return Value” value is that “0″ means the command was successful.
PSComputerName : xx.xx.xx.xx
RunspaceId : bf6f4a39-2338-4996-b75b-bjf5ef01ecaa
PSShowComputerName : True
__GENUS : 2
__CLASS : __PARAMETERS
__SUPERCLASS :
__DYNASTY : __PARAMETERS
__RELPATH :
__PROPERTY_COUNT : 2
__DERIVATION : {}
__SERVER :
__NAMESPACE :
__PATH :
ProcessId : 4808
ReturnValue : 0
I even added a line of code between the variable and the execution that creates a text file on the desktop, just to verify I was getting into my ‘executeFile’ file, and that text file does get created. It seems that it’s just not remotely executing my MSP.
Thank you in advance for your assistance!

Here's the strategy I used to embed an msp into a powershell script. It works perfectly for me.
$file = "z:\software\AcrobatUpdate.msp"
$silentArgs = "/passive"
$additionalInstallArgs = ""
Write-Debug "Running msiexec.exe /update $file $silentArgs"
$msiArgs = "/update `"$file`""
$msiArgs = "$msiArgs $silentArgs $additionalInstallArgs"
Start-Process -FilePath msiexec -ArgumentList $msiArgs -Wait
You probably don't need to use the variables if you don't want to, you could hardcode the values. I have this set up as a function to which I pass those arguments, but if this is more of a one-shot deal, it might be easier to hard-code the values.
Hope that helps!
using Start-Process for MSP package is not a good practice because some update package lockdown powershell libs and so you must use WMI call

twisted web server not ruuning a .rpy file

i am a toddler on Twisted .I am trying to run a Twisted web server using the command
twistd web --resource-script=~/Desktop/step/ecdemo.rpy
assume that my file(ecdemo.rpy) is located on desktop in step folder
the traceback when i visit the page(127.0.0.1:8080/ecdemo.rpy) shows
<type 'exceptions.IOError'>: [Errno 2] No such file or directory: '~/Desktop/step/ecdemo.rpy
however if i run the same file with command
python ecdemo.rpy it runs smoothly.
The program simply renders a get request from an http page
I know it is something basic that i do not know but if you could help me get started i would come up with better problems...
thanks for help.
Your shell didn't expand ~ into your home directory. Try this instead:
twistd web --resource-script ~/Desktop/step/ecdemo.rpy
Notice I removed the = between the option name and its value. This will probably let your shell turn ~ into /home/whoever.

Cant change memory usage in R

I am trying to change the memory usage for R on a windows 7 machine.
I go to the desktop shortcut > properties and try to change the target from
"C:\Program Files\R\R-2.13.0\bin\i386\Rgui.exe" to
"C:\Program Files\R\R-2.13.0\bin\i386\Rgui.exe" --max-mem-size=500M
as per this post https://stat.ethz.ch/pipermail/r-help/2010-June/241154.html
But I get an error message "The name '"C:\Program Files\R\R-2.13.0\bin\i386\Rgui.exe" --max-mem-size=500M' specified in the target box is not valid, make sure the path and file name are valid."
Any suggestions on how to fix this?
I just tried it. It works fine on my machine. Maybe you entered the --max.. in the "execute-in"-field instead of the "target"-field. If this is not the problem try this: create a .bat file and enter yourpath\Rgui.exe --max-..., then create a shortcut to that .bat.

Proxy setting for R

I am facing problem while conecting R with internet in my office. May be this due to LAN settings. I tried the almost all possible ways I come across in the web (see below) but still in vain.
Method1: Invoking R using --internet2
Method2: Invoking R by setting ~/Rgui.exe http_proxy=http:/999.99.99.99:8080/ http_proxy_user=ask
Method3: Setting Setinternet2=TRUE
Method4:
curl <- getCurlHandle()
curlSetOpt(.opts = list(proxy = '999.99.99.99:8080'), curl = curl)
Res <- getURL('http://www.cricinfo.com', curl = curl)
In above all methods I can able to load packages directly from CRAN also able to download files using download.file command
But using getURL(RCurl), readHTMLTable(XML), htmlTreeParse(XML) commands I am unable to extract web data. I am getting ~<HEAD>\n<TITLE>Access Denied</TITLE>\n</HEAD>~ error.
How to set LAN proxy settings for XML package in R?
On Mac OS, I found the best solution here. Quoting the author, two simple steps are:
1) Open Terminal and do the following:
export http_proxy=http://staff-proxy.ul.ie:8080
export HTTP_PROXY=http://staff-proxy.ul.ie:8080
2) Run R and do the following:
Sys.setenv(http_proxy="http://staff-proxy.ul.ie:8080")
double-check this with:
Sys.getenv("http_proxy")
I am behind university proxy, and this solution worked perfectly. The major issue is to export the items in Terminal before running R, both in upper- and lower-case.
For RStudio just you have to do this:
Firstly, open RStudio like always, select from the top menu:
Tools-Global Options-Packages
Uncheck the option: Use Internet Explorer library/proxy for HTTP
And then close the Rstudio, furthermore you have to:
Find the file (.Renviron) in your computer, most probably you would find it here: C:\Users\your user name\Documents. Note that if it does not exist you can creat it just by writing this command in RStudio:
file.edit('~/.Renviron')
Add these two lines to the initials of the file:
options(internet.info = 0)
http_proxy="http://user_id:password#your_proxy:your_port"
And that's it..??!!!
The problem is with your curl options – the RCurl package doesn't seem to use internet2.dll.
You need to specify the port separately, and will probably need to give your user login details as network credentials, e.g.,
opts <- list(
proxy = "999.999.999.999",
proxyusername = "mydomain\\myusername",
proxypassword = "mypassword",
proxyport = 8080
)
getURL("http://stackoverflow.com", .opts = opts)
Remember to escape any backslashes in your password. You may also need to wrap the URL in a call to curlEscape.
I had the same problem at my office and I solved it adding the proxy in the destination of the R shortcut; clik on right button of the R icon, preferences, and in the destination field add
"C:\Program Files\R\your_R_version\bin\Rgui.exe" http_proxy=http://user_id:passwod#your_proxy:your_port/
Be sure to put the directory where you have the R program installed. That works for me. Hope this help.
This post pertains to R proxy issues on *nix. You should know that R has many libraries/methods to fetch data over internet.
For 'curl', 'libcurl', 'wget' etc, just do the following:
Open a terminal. Type the following command:
sudo gedit /etc/R/Renviron.site
Enter the following lines:
http_proxy='http://username:password#abc.com:port/'
https_proxy='https://username:password#xyz.com:port/'
Replace username, password, abc.com, xyz.com and port with these settings specific to your network.
Quit R and launch again.
This should solve your problem with 'libcurl' and 'curl' method. However, I have not tried it with 'httr'. One way to do that with 'httr' only for that session is as follows:
library(httr)
set_config(use_proxy(url="abc.com",port=8080, username="username", password="password"))
You need to substitute settings specific to your n/w in relevant fields.
Inspired by all the responses related on the internet, finally I've found the solution to correctly configure the Proxy for R and Rstudio.
There are several steps to follow, perhaps some of the steps are useless, but the combination works!
Add environment variables http_proxy and https_proxy with proxy details.
variable name: http_proxy
variable value: https://user_id:password#your_proxy:your_port/
variable name: https_proxy
variable value: https:// user_id:password#your_proxy:your_port
If you start R from a desktop icon, you can add the --internet flag to the target line (right click -> Properties)
e.g."C:\Program Files\R\R-2.8.1\bin\Rgui.exe" --internet2
For RStudio just you have to do this:
Firstly, open RStudio like always, select from the top menu:
Tools-Global Options-Packages
Uncheck the option: Use Internet Explorer library/proxy for HTTP
Find the file (.Renviron) in your computer, most probably you would find it here: C:\Users\your user name\Documents.
Note that: if it does not exist you can create it just by writing this command in R:
file.edit('~/.Renviron')
Then add these six lines to the initials of the file:
options(internet.info = 0)
http_proxy = https:// user_id:password#your_proxy:your_port
http_proxy_user = user_id:password
https_proxy = https:// user_id:password0#your_proxy:your_port
https_proxy_user = user_id:password
ftp_proxy = user_id:password#your_proxy:your_port
Restart R. Type the following commands in R to assure that the configuration above works well:
Sys.getenv("http_proxy")
Sys.getenv("http_proxy_user")
Sys.getenv("https_proxy")
Sys.getenv("https_proxy_user")
Sys.getenv("ftp_proxy")
Now you can install the packages as you want by using the command like:
install.packages("mlr",method="libcurl")
It's important to add method="libcurl", otherwise it won't work.
On Windows 7 I solved this by going into my environment settings (try this link for how) and adding user variables http_proxy and https_proxy with my proxy details.
If you start R from a desktop icon, you can add the --internet flag to the target line (right click -> Properties) e.g.
"C:\Program Files\R\R-2.8.1\bin\Rgui.exe" --internet2
Simplest way to get everything working in RStudio under Windows 10:
Open up Internet Explorer, select Internet Options:
Open editor for Environment variables:
Add a variable HTTP_PROXY in form:
HTTP_PROXY=http://username:password#localhost:port/
Example:
HTTP_PROXY=http://John:JohnPassword#localhost:8080/
RStudio should work:
Tried all of these and also the solutions using netsh, winhttp etc.
Geek On Acid's answer helped me download packages from the server but none of these solutions worked for using the package I wanted to run (twitteR package).
The best solution is to use a software that let's you configure system-wide proxy.
FreeCap (free) and Proxifier (trial) worked perfectly for me at my company.
Please note that you need to remove proxy settings from your browser and any other apps that you have configured to use proxy as these tools provide system-wide proxy for all network traffic from your computer.
Find your R home with R.home("home")
Add following lines to Renviron.site in your R home
http_proxy=http://proxy.dom.com/
http_proxy_user=user:passwd
https_proxy=https://proxy.dom.com/
https_proxy_user=user:passwd
Open R -> R reads Renviron.site in its home -> it should work :)
My solution on a Windows 7 (32bit). R version 3.0.2
Sys.setenv(http_proxy="http://proxy.*_add_your_proxy_here_*:8080")
setInternt2
updateR(2)
