library(RWeka) gives this error:

Error in get(Info[i, 1], envir = env) : lazy-load database 'C:/Users/Richard/Documents/R/win-library/3.1/rJava/R/rJava.rdb' is corrupt In addition: Warning message: In get(Info[i, 1], envir = env) : internal error -3 in R_decompress1 Error: package or namespace load failed for ‘RWeka’

I have also updated Java. I am using Windows 10 and RStudio.

I have removed.packages("rJava") and ("RWeka"). Then I installed.packages("rJava") and ("RWeka"). Still getting this message.

  • Can you load the rJava package on it's own? – Derek Corcoran Jan 09 '17 at 16:10
  • Yes, no error after install.packages("rJava") or install.packages("RWeka"). The errors are seen after: > library(RWeka) Error in get(Info[i, 1], envir = env) : lazy-load database 'C:/Users/Richard/Documents/R/win-library/3.1/rJava/R/rJava.rdb' is corrupt In addition: Warning message: In get(Info[i, 1], envir = env) : internal error -3 in R_decompress1 Error: package or namespace load failed for ‘RWeka’ – RProgrammer Jan 09 '17 at 17:20

    If anyone can help I would appreciate it. I have removed and reinstalled both rJava and RWeka. They both install. The problem is when I use library(RWeka) or library(RWeka) I get error message (see above). If RWeka does not work, I have to figure out something equivalent to the OneR method. – RProgrammer Jan 10 '17 at 22:19
  • Use the OneR packages for the OneR method. – Endre Jun 12 '19 at 00:11
