RWeka installation under Rstudio on Mac

Question

I tried to find solutions from previous posts, but they do not solve my problem.

I am using macOS High Sierra and have Java installed. Below is the error reported by Rstudio. Also, rJava, Mac, and R are really messy with each other. I found this post but still does not work.

Answer 1

I met the same question and I found this is helpful. Cannot load R xlsx package on Mac OS 10.11

1.In terminal enter the following to relink Java correctly:

sudo R CMD javareconf 

2.Back in R (or RStudio) install the rJava package from source:

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

Then library(rJava) and library(RWeka) should work.
