Unable to load r java package

[l3ikrant]

I am using in Windows and install_github("unhcr/koboloadeR", ref = "gh-pages") fails due to ..

it searches rJava in users/USER/Documents/R/win-library/3.5/rJava/libs/x64/rJava.dll path back slash (/) But the file exists in C:\Users\USER\Documents\R\win-library\3.5\rJava\libs\x64 (front slash )

Same Happened to my windows a months ago. I installed 64 bit R, 64 bit Java. And still the problem occured. I switched to Ubuntu.

As you can see in the readme - If you get this error:

Error: package or namespace load failed for 'rJava'

It could be because you have a 64bit version of R, but have a 32bit version of Java. Check this thread for guidance: https://stackoverflow.com/questions/37735108/r-error-onload-failed-in-loadnamespace-for-rjava

Find where your Java is installed then set it up in your environment - You may need to restrart Rstudio once done For instance - depending on where Java is installed, use the command: Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jre7') # for 64-bit version

After Trying For instance - depending on where Java is installed, use the command: Sys.setenv(JAVA_HOME='C:\Program Files\Java\jre7') # for 64-bit version

library(rJava) still fails rJava doesnot exists for R 3..

I do have both 32 bit and 64 bit R and Rstudio May be uninstalling 32 bit r and rstudio and using Only One helps.

Did you try to close Rstudio and reopen it before launching Rjava?

This addressed the issue when I faced it...

Sorry for late response. But I am sure the mistake was from myside with some Java version or path problem. I switched to ubuntu and its working fine.
