I have R installed on my system, but R studio does not appear to recognise it. Please advise on how I should proceed.
This is the error:
R doesn't seem to be installed. Before using R studio, please install R.
I have been able to fix the problem. I uninstalled the one I downloaded early and installed the base version

I'm trying to install an old package I had in RStudio for an old version of RStudio but I get the following:
Warning in install.packages :
package ‘d3heatmap’ is not available (for R version 4.0.0)
I'm trying to install d3heatmap but ever since I upgraded to 4.0, I can't install it. I'm thinking I have to install an old version of RStudio. But I want to verify if d3heatmap is still available and what versions it still works for but I can't find any information on it.
Anyone able to help me out?
you can downloaded the zip file here (https://cran.r-project.org/src/contrib/Archive/d3heatmap/)
and run this code in Rstudio
install.packages("d3heatmap_0.6.1.2.tar.gz",repos=NULL,type="source")
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 If your Rstudio is outdated (version 0.*.*) it might have problems with the newest versions of R.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.
Running happily with R 3.4 and RStudio 1.0.143 under Win10 this problem occured bringing project development to a halt. Downloads each occur and are unzipped and then the a presumably first file in the first item gets:
Error in install.packages : cannot open file 'C:/Users/Admin/Documents/R/
win-library/3.4/file30504386b80/rJava/javadoc/resources/background.gif':
Permission denied
and the prompt returns.
Updating to R version 3.4.1 (2017-06-30), RStudio Version 1.0.153 was to no avail. Using the OS to remolve all R versions and trying again with 3.4.1 did not work. Removing R again and deleting the R directory to refresh the library did not work. My virius software like to tell how helpful it has been and has not, so that issue seems unlikely.
Giving the user full control of the R library did not help.
could package-updates be a tag like install-updates?
It looks there is a problem between Java and rJava.
You should try reinstalling Java using chocolatey package manager (https://chocolatey.org/) and then reinstall rJava package.
I had a similar issue two weeks ago on a windows laptop.
I had this problem for a long time. only in RStudio.
Install the package on R and Library it. Go to RStudio and require the package.
It works!
How do I install an old version of R on a window 10 64 PC.
I am currently running R 3.2.3 with RStudio without any problems. However a package I want to use (GSIF) only works on R2.15. I have found that it is possible to easily get RStudio to work with different R versions and I have found and downloaded the old version of R I want ( R-2.15.1-w.tar.gz) from the CRAN archives. My problems is cannot work out how to install the R-2.15.1-w.tar.gz package on a windows machine or in fact even if it is the right package for windows. All the instruction I can find seem to relate to Linux.
Any guidance greatly appreciated.
You can hold down the Control key during the launch of RStudio you can cause the R version selection dialog to display at startup.

I feel pretty comfortable working with R, and I want to get into Python through Anaconda.
Upon trying the Jupyter Notebook and finding it has compatibility with R, I really want to use it.
I'm having problem installing the R packages that don't come in R-essentials; and mainly because I noticed it uses a different R installation than the one I had before. Not only is this a different R installation, but it also uses a previous version of R. In my local installation I have updated to 3.2.3 but in the Anaconda environment for Jupyter I got 3.1.
I also found a post to change the .libPaths variable to include the packages that I had already installed. Still, I see this as a potential problem because of the different R versions.
I wanted to know if I can update the R version that's used in Anaconda, or if I can point to the one that's installed locally.
Thank you.
You can install IRkernel in the normal R installation and then register the kernel: simply follow the instructions at http://irkernel.github.io/installation/
