I am kinda confused with upgrading R Studio. I have two questions.
1) As of today, July 10th 2017, is (RStudio v1.0.147 Preview) the most recent version? I've included the link to this version: https://www.rstudio.com/products/rstudio/download/preview/
2) I already have R studio on my cpu ( I don't know which version).
I would like to download the most recent version of R studio.
So, if I do need to download the abovementioned version, do I uninstall my current R Studio and then install it again from the above link? Or do I NOT need to uninstall R Studio but simply download the version in the above link?
Thanks,
Why don't you just update the RStudio from RStudio.
Help --> Check for updates
No need to uninstall.
You can download and install the new version of R Studio with no issues. I've done so many times on my windows PC.
Not sure of behaviour on linux & clones.
The new version you install should automatically point to your latest R version also and if not you can easily tell it to in the tools global options menu.
Just update R Studio instead of uninstalling it. Even if you have downloaded you can give change and repair and install it rather uninstalling it.

Recently I've tried to install keras package in R. I ran the following commands:
install.packages("keras") library(keras)
But when I ran is_keras_avalable() I got FALSE.
I was told, that the problem with unsuccessful 'keras' installation may come from the old RStudio version, which is installed on my notebook (I work in RStudio 3.4.0). I was adviced to reinstall RStudio and to get a brand new version.
Could you, please, tell me how to do it? I'd be very pleased if you provide me with the necessary links for installing the latest RStudio version on Windows 8.1.
Thank you for your help.
RStudio is an application (specifically, an Integrated Development Environment, or IDE). This is a common tool for using R, which is a computer language. Much like Microsoft Word is a common tool for writing documents in English (or other languages - and in fact you can use RStudio to write files other languages like RMarkdown, Python, SQL, French, or Swahili.). However, just like you can write English in programs other than Word, you can also write and run R code in programs other than RStudio.
You can find the most recent version on the RStudio website, or you can look in the Help menu and select "Check for updates", which will give you a download link if a newer version is available.
Given the version number you show, 3.4.0, you need to upgrade R (the language), not RStudio (the application). The current RStudio version as I write this is 1.3.*, while the current R version is 4.0.*.
The place you need to go to update R is CRAN - their website has download links for Windows, Mac, and Linux.
MacOS: High Sierra, version 10.13.6
R version: 3.6.1
R studio verison: 1.2.1335
I have been using Anaconda to manage my R packages for a while now. However, I keep getting errors in regards to C and Fortran compilers when trying to install and run packages that depend on them through the Anaconda R studio distribution. Thus I started using the stand-alone version of R studio again. I use the tcltk package in pretty much all of my scripts to easily choose file paths to load multiple data sets etc. When using the tcltk::tk_choose.files() command through the Anaconda R studio distribution, the file explorer window looks like the standard file explorer in MacOS. However, when using the same command in the stand-alone version the file explorer looks like this when running through XQuartz/X11:
My question is why the file explorer suddenly looks this "old" and if there is a way to fix it so I can continue using tcltk? Otherwise are there any alternatives?
I have tried out rJava together with rChoiceDialogs but I cannot get the rChoiceDialogs::jchoose.files() to work.
I managed to solve the issue. Meaning the file explorer looks normal again. I uninstalled my R, RStudio, and XQuartz. I then reinstalled all three using homebrew following the guide posted here.
I have R 3.4.3 installed on my computer. When I point R Studio to this version of R, the program loads a white screen.
Is R Studio compatible with R 3.4.x? What is the highest version of compatibility?
It actually would depend on the version of Rstudio. For the latest ones - yes it is. If your Rstudio is outdated (version 0.*.*) it might have problems with the newest versions of R.
The first step would be to check your R installation. Start R without Rstudio and see if it works. If it doesn't you need to re-install R. If R works fine, then reinstalling Rstudio might be the easiest solution.
Thought I'd give MRO a spin, to see if it speeds up my usage in general.
I can't find the installed R though. Not as a separate, not as an overwrite.
/usr/local/bin/R contains R version 3.4.0 (2017-04-21) -- "You Stupid Darkness", which is also the one used by RStudio.
/Library/Frameworks/R.framework/Versions/ also only contains 3.4.
The GUI "Microsoft R Open.app" has the description R 3.3.0 GUI 1.68 Mavericks build... but it also returns 3.4.
What am I missing?
You've identified a bug in the installer. Thanks!
Looks like we are not installing the MRO framework files because the package installer is detecting a newer version (CRAN 3.4). We will get this fixed in the next release.
In the meantime, you can work around this by renaming /Library/Frameworks/R.framework/Versions/3.4 to /Library/Frameworks/R.framework/Versions/0.3.4 and reinstalling MRO. Then go ahead and rename it back.
Please note, as a part of the install we update the symlinks to point to our version, so if you would prefer the default R installation to be CRAN 3.4 please do the install in the reverse order or manually update the symlink to Current in the Versions folder.
Many people use R and RStudio and they need to keep up with upgrades.
If one wants all RStudio projects to be "remembered". Is is possible? A seamless upgrade of both....
Should one first install new R version and then install RStudio into the same folder. (what is the best order of steps?)
Updating RStudio is no problem. You just go to Help > Check updates in the menu, and RStudio will take care of the rest. It also recognizes the latest installed R version on your computer, so just installing the new R should suffice for that. Note that project files are saved on your computer, and can of course be opened with the new version of RStudio you installed.
Regarding keeping the settings for your R version, see eg:
Painless way to install a new version of R?
Gabor Grothendieck has a package 'batchfiles' on Google Code as well as in CRAN's extra directory which does this.
