When I access the RStudio (hosted on a server) shell (Tools > Shell...), I gain admin access by using sudo R, then typing my password, which I know is invisible for security reasons. However, every subsequent line of code I type is also invisible.
For example, say I want to download a package to make it available on the server. I use:
install.packages("spls", lib="/usr/lib/R/library")
The above text does not show up, but when I press Enter, it does execute and I'm asked for a mirror to use. The package then is correctly installed. Thus, the only problem is not being able to see the text. This happens for anything I type in the shell.
I'm not the host of the server, but I do know it uses Ubuntu, I believe the RStudio version is 0.99.473 and the R version is definitely 3.2.1. I'm running on a Mac with Yosemite and Safari. If more specific information would be helpful, I can contact the host.
Does anyone know what might be causing this issue and how to fix it?

Unfortunately, I made a change to the Jupyter Lab settings recently. Jupyter had never been able to access the remote R help server. Usually this was never an issue because most help files are displayed in Jupyter. The way help is called on a function or method is typing: ?question. The "question" being the name of an R function or method. Ex. ?plot
Infrequently one of the R packages will not list its help in Jupyter and instead try to open the remote R help server. This has never worked in the past. The tab for a remote server never opened. This has never really been an issue until recently. Recently I decided to "fix" this issue and spent a good deal of time looking up the solution. I made this "fix" and Jupyter began working properly to open the remote R help server. But the fix is a problem that is way too obnoxious.
Each time I type the question mark in Jupyter, Jupyter causes the browser to open a new tab for the remote R help server. It is impossible to type fast enough after typing typing the ?. Once the ? is typed, the typing is interupted while the browser opens a new R server help website. As soon as returning to the typing, another browser tab opens and interrupts the typing .
It is impossible to finish typing the name of a function after the ? without having multiple interruptions to the typing while multiple new windows are opened in the browser at the R help server website. By the time I've finished typing: ?ppp, there will the 5 interruptions and new browser tabs opened. If I typed slowly, there may be 10 - 12 interruptions and 10 new tabs opened at the R help server.
How to prevent Jupyter from trying to access the remote R help server every time the ? is typed when looking up a description of a function? How to get back to that happy place I had before I'd made whatever change that caused this nightmare to happen?
Solved my own question.
This issue had nothing to do with R. I assumed I had changed a configuration in R, but that was not the case. This was an issue I had caused when I had changed a setting in Jupyter lab.
I can say with certainty this issue was definitely caused when I changed the "Contextual Help" setting under the Commands tab in Jupyter. This setting is related to the Contextual Help selection found under the Help tab. And this setting was causing multiple R help server tabs to open in the browser after I typed: ?
Upon rediscovering this Jupyter setting today I recalling that I had been down this path before. I selected "Contextual Help". Jupyter auto restarted and the issue went away. I can gladly say that I can perform search again for the description of an R function: Ex ?plot ,and receive the description of this function within Jupyter the same as before. I no longer have the issue of the browser opening or multiple new tabs at the remote R help server after typing ?
I have been using R on commandline (BASH). I am unable to access the internet (download any packages). I have tried proxy system wide, and tested it with wget, which works. The "install.packages()" command however does not.
Per some user's advice, I also tried setting the proxy in .Rprofiles file. That didn't help either. Please advice.
I recently ran into the same issue on my work machine. Our Firm uses Cylance as its antivirus software. Cylance was quarantining the file "internet.dll" that R uses to access the Internet. Fortunately, however, it only does so in the 32-bit version of R. For me, there were two solutions:
First, I was able to download packages directly from the 32-bit version of R (outside of RStudio). This works fine. The downloaded packages will run in 64-bit RStudio.
The longer-term solution was to submit an IT service request to release this file from quarantine (that is, to "whitelist a blocked entity"). At my Firm this was promptly done, as there is (obviously) nothing unsafe about this R file.
I am a novice in the use of Python and I am using PandasBiogeme to estimate discrete choice models.
My issue is related to the Jupyter notebook. Usually when I wish to use it, I select it from the start menu of Windows 7 and automatically a new tab opens up in Chrome.
Yesterday, actually by not knowing exactly why, I logged out from Jupyter notebook and today when I launched it from the start menu the following error message appeared:
I thus decided to reinstall Anaconda, and PandasBiogeme and to update both of them.
Now when I wish to open Jupyter notebook from the start menu a prompt menu appears and suddenly disappears. Therefore I need to open the Anaconda Powershell and type
jupyter notebook
Yet, when I do this I receive the same error message I reported above
I typed in the second URL and I was then able to work again.
Yet, when I close Jupyter notebook and try to launch it again the same problem arises and I have to insert again 'a' token. I wrote 'a' token, because if I select by chance the token reported at the following URL (which has nothing to do with my work)
https://jupyter-notebook.readthedocs.io/en/stable/security.html
namely, this one:
http://localhost:8888/?token=c8de56fa4deed24899803e93c227592aef6538f93025fe01
and then Jupyter notebook works and I can carry out my estimation.
I read different posts on the possibility to set a password to avoid problems related to tokens, but only the first time I inserted the token I had the option to insert a password in in a html page, but I decided not to do it. Now I believe it could be the case.
This is something that happened overnight, without, I believe, my doing anything specifically.
This issue is driving me crazy and I would be thankful if any of you had a potential suggestion.
Many thanks.

Using atom-editor 1.13 with the love-ide package installed to run LOVE2d 10.2 games (windows 7)
Apparently if you create a conf.lua file in the same folder as your main.lua file you can add some configuations to main.lua. So, I've got these lines of code in my conf.lua to show console.
function love.conf(t)
t.console = true
end
But when I go back to my main.lua and type print("ballz"), all I see is a blank LOVE2d game screen with no extra console window. Not really sure if this is because I'm using atom editor or not. Everything seems to be PATH'ed correctly.
On a side note, whenever I run atom using the love-ide package it always tries to install some "dependecy files" like the hyperclick-love package, and the auto-complete-love package. These fail to install because I don't have git installed.. honestly I really don't know what git is, but neither it, hyperclick, or auto-complete seemed like requirements to run my game, so in the spirit of not installing unnecessary things onto my computer I never installed these things... annoying as it is to see this notification always pop up when I start atom. Anyone know if this is contributing to the issue, or know a way to remove these notifications or auto-download-attempts? My LOVE2d code still seems to run without these packages.
Have you set up the terminal emulator in your configuration?
(Windows only) Try using the lovec.exe executable instead of the normal love.exe. The first one attaches to the console that executed the game, the second one ignores it.
Lua has a buffered output, try adding io.stdout:setvbuf('no') to the top of main.lua
sorry if this question is not as detailed and focused as it should be.
I am a Linux user (so no admin privileges of any sort) and just installed Anaconda3 from here and followed the instructions.
Note that my Linux machine is not connected to the internet, so I had to transfer the file through other means and just run bash Anaconda... as instructed in the Continuum site.
I have then succesfully launched IPython and tried to plot inline, without problems. However, when I tried to use plotting in windows, I got this kind of output from the terminal:
X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea)
And the created graph window was just blank.
I then tried to start Spyder and basically saw the same behaviour: a lot of those errors reported above, and the Spyder window just popped up blank.
Google search for the error gives results reported for Qt, which makes sense since when plotting "offline" (as opposed to inline) then QtAgg is used.
However, I have no clue as to where to look for the version of these libs, how to install/compile new ones, whether that is really the issue or not. I am just to ignorant about Linux.
Anybody can hint on what to look for and how to try to debug this behaviour?
I had the same error. What worked for me is to add this line in /etc/environment.
sudo nano /etc/environment
Add this line
QT_X11_NO_MITSHM=1
Source : https://github.com/P0cL4bs/WiFi-Pumpkin/issues/53#issuecomment-309120875
Note that in my case the fix didn't take effect until I rebooted my machine.
you may simply run on the terminal:
export QT_X11_NO_MITSHM=1
I had this same error, so I'll tell you what worked for me.
I think it is a permissions issue, based on the following:
I was logged in through a VNC server window through my account, but within the VNC server was setting up a user profile for "user2". In a 'user2' console I installed anaconda in user2's directory. When I typed spyder in the user2 console, I got the exact error you describe. I guessed the VNC desktop didn't like user2 trying to open a window on user1's profile. I then logged out of my VNC server window, logged into the user2 vnc server window, and in a console typed 'spyder' and it opened perfectly.
I think for some reason it is trying to open but is installed in a directory that you don't have permissions for or trying to open in a window that you don't have access to.
