Ubuntu 16.04 Rstudio Can't input Chinese.
My OS all setting done for English. I tried all the methods，including link files、installed qt5、switch fcitx,but all were failed.
Sincerely I want to ask what method can solve this.
Sys.setlocale(category="LC_ALL",locale="en_US.UTF-8")
You may try your luck with this code. But I think R is not very compatible with other language rather than English. Since the R version I installed in my Chinese OS caused tons of issues.

Sometimes I need to use older version of R in RStudio but I don't want to downgrade R permanently. RStudio for Windows offers a comfortable tool for switching R versions. It is sufficient to open Tools > Global Options > General and switch R version as shown in the picture. But it is not available in RStudio for Linux. I would appreciate some easy and fast method for switching R version, not upgrading/downgrading.
Thanks in advance for answers.
I have a CRAN package that has inputenc errors when creating vignette PDF outputs in a strict Latin1 locale. The check results have errors for flavor
r-devel-linux-x86_64-debian-clang, which uses LANG=en_US.iso885915. I believe I may have fixed the problem (it was a warning on my Mac). However, I feel I should check the problem on Linux as well before submitting bug fixes to CRAN. It was suggested to me that to check that my package fixes the error on LANG=en_US.iso885915, that I should run the following command on Linux:
LANG=en_US.iso88591 R CMD check
I do not have access to Linux and will not for the reasonably foreseeable future. I am trying to figure out how to run this command on my macOS Catalina (version 10.15.3). With little experience running Linux on Mac, I have been doing searches online, with an example forum here. There are some negatives discussed there, including the lack of necessity of running Linux on Mac (usually), installation of Linux restraints on latest MacBooks, and virtual machines not truly representing what Linux can do.
I decided it may be helpful for me to ask here on SO. I do not have too much storage left on my Mac and I would likely delete any Linux installations quickly since I will likely not need them outside of this one issue. I also do not have much experience installing virtual machines and Linux. I also hope to avoid any other risks I may not even be aware of to my computer.
What is the best way (convenient, low risk, quick, low storage requirements) you may know for someone in my position to check this recommended command (LANG=en_US.iso88591 R CMD check) with access to simply my MacBook Pro (Retina, 13-inch, Early 2015)? Thank you for sharing suggestions!
After Ubuntu upgrade(18.04), my atom editor has changed like the attached picture, which is quite hard to read.
Especially, 'ImportError' looks like 'ImpprtError.
How can I solve this problem?
Thank you.
This is likely a problem with FreeType, there are several reports on the Atom forum. Try if updating Atom and/or FreeType solves the issue.
I have upgraded R from 3.3.3 to 3.4.1 and am finding that typing text directly into the R Console quickly becomes very laggy, even when R isn't using a lot of resources. I have observed this behavior running the last couple versions of macos sierra (10.12.6, etc.).
It is notable that R functions are not particularly slow when executed. Most of the time I use Textmate 2 to pass code to the console and the code passed in this fashion runs without delay.
I've done extensive searching, but I haven't found anyone else reporting this problem. I've found this behavior on two different macs: 2013 Macbook 13" and 2017 Macbook 15" and have encountered the same problem.
Is there an easy solution to this problem that I'm missing?
The only answer I have been able to find is to roll back R to version 3.3.3, which is the last version before R began using Clang and GNU Fortran to compile the executable (https://cran.r-project.org/bin/macosx/ for more info).
This is not an optimal solution since I have to go back to previous versions of some packages I use (which is further complicated by the hunt for the right version of problematic dependencies). I have been looking through the r-devel threads and don't see a discussion of this, which surprises me because I know that I can't be the only person dealing with this. I will contact the r-devel folks and will update here if I get any additional info.
Update
The discussion on this question has identified that the issue is with the macos R GUI. Unfortunately, it appears that the R GUI developers are aware of this issue, but it is not being listed as a bug. The developers suggest clearing the console – not a workable solution for me given how quickly the problem crops up.
I have come up with a better solution, though it is kind of odd. I realized that since the problem is with the GUI and not R, you can take an old version of the GUI (they are available from the R macos development page). I was hoping to be able to use GUI version 1.69, but this caused a crash immediately. version 1.68 on the other hand does work.
I installed R 3.4.1 on my computer and then downloaded the binary file for GUI version 1.68 and copied it into my applications folder (you don't have to do this, but if you do, make sure to rename the program because otherwise you will replace R). I think opened R via the GUI and loaded R 3.4.1 on R Mac GUI version 1.68. So far it seems to be working fine, confirming that the problem is indeed in the GUI.
The issue actually appeared long ago (at R3.1.2 release) once the developers started to use a newer version of Xcode (I think they moved from v.5 to v.8 and above). At that time Simon told me that this is Xcode and Apple's problem, so they can't do anything about it. He did however forced the compilation with an older Xcode which "avoided" the issue till R3.4. I presume they can no longer use this work-around.
Possible solution:
Try running: rm(list = ls(all.names = TRUE)) This should remove everything from your R console, including hidden objects.
Then run .rs.restartR(), which will restart R. Hopefully, whatever is clogging up the program will be gone.
Have you tried RStudio? I highly recommend that GUI to work with R.
If you need more speed you should considering using R with modified matrix products. For example, to use R with openBLAS I wrote a tutorial here: http://pacha.hk/2017-07-12_r_and_python_via_homebrew.html
Suddenly, today, the font that R uses in its gui window looks like this:
How can I get it to look nice again?
Note:
I do not want to specify fonts in plots.
I'm on a Mac under OS 10.9.5 using R 3.0.2.
Hmm, I don't know what the problem was, but updating R to the most recent version turned on antialiasing again:
As David Arenburg noted in a comment above, the problem might have been caused by remote access: I accessed this laptop from my desktop iMac yesterday to do a backup. Also I'm currently building fonts with FontForge, and the problem might be related to this (unfinished fonts lying around somewhere).
Anyway, the new installation did it (for the moment). If anyone knows how to analyse and solve this problem without installing, please post an answer.
