> library(Rook)
> s <- Rhttpd$new()
> s$add(name='MyApp',plot_ind_brz='D:/STOCK/plot_ind_brz.R')
I am getting an error
"Error in s$add(name = "MyApp", plot_ind_brz = "D:/STOCK/plot_ind_brz.R") :
unused argument(s) (plot_ind_brz = "D:/STOCK/plot_ind_brz.R")"
And steps are written as follows:
Load Rook
library(Rook)
Create an Rhttpd variable
s <- Rhttpd$new()
Create your application in a separate file, assign it to either the
name of your application or simply just 'app'.
Add your application to the server:
s$add(name='MyApp',app='path/to/your/app.R')
Load the app into your browser
s$browse('MyApp')"
How to resolve this problem? Can anyone please help me on this?
In the instructions, app is the name of a formal parameter to the add() function. Even if your app is named differently, this has to remain unchanged:
s$add(name='MyApp', app='D:/STOCK/plot_ind_brz.R')

While accessing to CSV file from disk with the help of the R program, where a path to the CSV file is provided in the configuration file ( A path is like "testData/Amazon S3/Inventory/Accounts.csv" which is provided in the Configuration file and cfig[2]$save.location is variable who is having value of this path accessed from Configuration file). Few lines of code are below
path <- cfig[2]$save.location
test_data <- fread(path,stringsAsFactors = FALSE,drop=col_ignor,blank.lines.skip = TRUE)
but it gave the message below:

It gives an error like as, Error in [<-.data.table(*tmp*, j, value = list(TestCaseID = "C419760", : Supplied 14 columns to be assigned 15 items. Please see NEWS for v1.12.2.
The above error was a warning but after manually updating of packages. This warning turns into an error. What will be the reason behind this issue and how to solve it? Thanks for Advance!!!
I'm trying to insert a url into a postgresql database using
db_insert_into(con, "url", "http://www.google.com")
Error in file(fn, open = "r") : cannot open the connection
In addition: Warning message:
In file(fn, open = "r") :
cannot open file 'http:/www.google.com': No such file or directory
How can I solve this?
You need to somehow specify both the table name and the field name. I'm going to guess that "url" is the field name, and the table name is as yet undefined here. But it doesn't matter, frankly, take the solution and adapt as needed.
The expectation of db_insert_into is that the values (third argument) is a data.frame or something that can easily be converted to such. So you can probably do:
newdata <- data.frame(url = "http://www.google.com", stringsAsFactors = FALSE)
db_insert_into(con, "tablename", newdata)
If you're lazy or playing code-golf, you might be able to do it with:
db_insert_into(con, "tablename", list(url = "http://google.com"))
since some of the underlying S3 or S4 methods around dbplyr sometimes check if (!is.data.frame(values)) values <- as.data.frame(values). (But I wouldn't necessarily rely on that, it's usually better to be explicit.)
I am trying to open a device, but getting the following error:
> trellis.device(device="pdf", filename="runtime.pdf")
Error in device.call(...) : unused argument (filename = "runtime.pdf")
The same error does occur when I try to open a device with
pdf(filename="c:/R/FSM/runtime.pdf")
Is there a package that I need to load into the library?
The correct argument is file rather than filename, as in pdf(file = "myfile.pdf"). Other functions that open new devices do use the filename argument, such as jpeg(), so you need to check the help file. In general, the error that was returned Error in ...: unused argument indicates that an argument supplied in the function call is not part of the function.
I'm working for the first time with the R package BerkeleyEarth, and attempting to use its convenience functions to access the BEST data. I think maybe it's just a problem with their servers (a matter I've separately addressed to the package's maintainer) but I wanted to know if it's instead something silly I'm doing.
To reproduce my fault
library(BerkeleyEarth)
downloadBerkeley()
which provides the following error message
trying URL 'http://download.berkeleyearth.org/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip'
Error in download.file(urls$Url[thisUrl], destfile = file.path(destDir, :
cannot open URL 'http://download.berkeleyearth.org/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip'
In addition: Warning message:
In download.file(urls$Url[thisUrl], destfile = file.path(destDir, :
InternetOpenUrl failed: 'A connection with the server could not be established'
Has anyone had a better experience using this package?
The error message is pointing to a different URL than one should get judging what URLs are listed at http://berkeleyearth.org/data/ that point to the zip formatted files. There are another set of .nc files that appear to be more recent. I would replace the entries in the BerkeleyUrls dataframe with the ones that match your analysis strategy:
This is the current URL that should be in position 1,1:
http://berkeleyearth.lbl.gov/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip
And this is the one that is in the package dataframe:
> BerkeleyUrls[1,1]
[1] "http://download.berkeleyearth.org/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip"
I suppose you could try:
BerkeleyUrls[, 1] <- sub( "download\\.berkeleyearth\\.org", "berkeleyearth.lbl.gov", BerkeleyUrls[, 1])

Appreciate any ideas on this.
Thanks,
This is not an R-related problem, but a problem of accessibility. The error message seems rather clear to me: the server has no reading rights for that file. Make sure you share the file or folder you want to read in. I don't know what the setup is of the network and clusters wherever you're located, but you better contact the admins to ask how you get your files to the right places.
Also make sure that if you transfer files to the servers/cluster, you adapt your R script so it points to the right directories. Which is probably not your own harddrive...
When you say
transfer_input_files = C:/Users/OmegaAdmin/Desktop/test_case/two.R
That tells Condor to copy two.R into the current working directory when the job starts. The current working directory is a specially created workspace, not (usually) a home directory. Thus I would expect the full path to look something like
C:/condor/execute/dir_28412/two.R
However, R is actually looking in
C:/Users/pcname/Desktop/test_case/two.R
Why is R looking there? Does one.R potentially say "Find two.R in $HOME/Desktop/test_case"? Does it perhaps say, "Look in Desktop/testcase/two.R" and R has configuration that wants to look relative to the user's home directory?
The solution is almost certainly to modify one.R or your R configuration to look for two.R in the current working directory. If for some reason R changes its current working directory, the environment variable _CONDOR_SCRATCH_DIR should contain it.
On a related note, you said:
arguments = one.R
input = one.R
The first is an argument passed to Rscript.exe, which I'm guessing tells R to load and run a file called one.R. Except that script isn't present! If you want that to work, you'll need to add it to transfer_input_files. But it obviously appears to work; why? Because "input=one.R" means "take the contents of one.R and pipe it in as standard input to Rscript.exe; the same as if you'd typed those contents in." I'm guessing you can remove the arguments, or remove the input and add one.R to your transfer_input_files, removing the ambiguity.
