R - Error : .onLoad failed in loadNamespace() for 'rJava'

Question

While loading rJava package, I receive this error:

Error : .onLoad failed in loadNamespace() for \'rJava\', details:
  call: inDL(x         


        

Answer 1

I encountered the same problem. Be sure to check the file path for Java. To solve the error I needed to download 64bit Java version. However the following code in R did not work as the folder was incorrect for the latest version for Java:

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jre7') # for 64-bit version

Instead I changed the name to:

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jre1.8.0_144') 

Hope that helps
