I previously had some raw data in the R language using the mediation package analysis and then wanted to use Mathematica for subsequent analysis. This process is not very smooth. Please help.
Needs["RLink`"]
RLinkResourcesInstall[]
InstallR["RHomeLocation" -> "C:\\Program Files\\R\\R-3.5.1"]
An error message appears:
InstallR::fail: Failed to install R. The following error was encountered: Unable to load dynamic libraries
I have just recently installed RLink on Windows, with Mathematica 11.3. I was unable to get R v3.5.1 to work, and the same “unable to load dynamic libraries” message kept popping up, however it seems to be running well with R v 3.4.1.
It would be helpful if Wolfram could put a prominent note in the documentation about which version(s) of R they are supporting with RLink.
If you have rJava installed already, try this, for example,
Needs["RLink`"]
JLink`UninstallJava[]
InstallR["RHomeLocation" ->
"C:\\Data-Work\\Programs\\R-3.5.1\\App\\R-Portable",
"NativeLibLocation" ->
"C:\\Data-Work\\Programs\\R-3.5.1\\App\\R-Portable\\library\\rJava\\\
jri\\x64"]
REvaluate["R.Version()"]
I’m using Window 10 (1803) and Mathematica 11.3.
“RHomeLocation” - path to your R and “NativeLibLocation” - path to Java R Interface
Thanks for the tip, I’ll give it a try when I get some time.
