There is a binary version available but the source version is later:

From experience, I believe there is a difference between Java and Java Offline.

Try installing the x86/x64 offline version from http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html (A handy link to keep hold of)

  • What is in your environment variables? Do you have a link to java in there? Mine is linking to C:\ProgramData\Oracle\Java\javapath. If you don't have that then maybe try adding it – Jason Dealey May 16 '17 at 10:17
  • i want to find word associations. Therefore, i need the package Rweka, and therefore i need to have java... i do not know where i need to link to the java path... – Doris May 16 '17 at 13:10
  • Start menu > start searching for 'environment variables' in the search bar and click on it > Under System variables, look for PATH and edit it > You'll need to add the javapath location above into this (semi-colon separates each path) > TO EXPLAIN: Whenever an install looks for a program, it will look through your environment variables for the matching program name. It looks as if RWeka cannot find your java install. Hope this helps. – Jason Dealey May 16 '17 at 13:25
  • i don't really get what you mean. Do you mean on my computer (i have a mac) or do you mean in rstudio? because i can not find environment variables in rstudio – Doris May 18 '17 at 07:16
  • Ah Mac. Not got a clue in that regards. I thought you were working with windows – Jason Dealey May 18 '17 at 09:33

If you have the newest Java, just open a terminal and run

sudo R CMD javareconf

Then in a R-session,

install.packages("rJava",type='source')

install.packages("RWeka")
