rJava install error “JAVA_HOME cannot be determined from the Registry”

Question

I am trying to load the rJava using the command:

 library(rJava)

But I get the following error:

 Error : .onLoad failed i         


        

Answer 1

I got the same error resolved by installing same version of R and Java i.e. 64 bits and manually updating the path i.e. ,

Sys.setenv(JAVA_HOME='C:/Program Files/Java/jre1.8.0_121') # for 64-bit version
