[R] Problem Installing rJava on MS Win 7 Platform

[Stephen P Molnar]

Thanks for the reply.

Yes, you are quite correct, but:

> install.packages('rJava')
Warning in install.packages("rJava") :
  argument 'lib' is missing: using
'C:\Users\Stephen\Documents/R/win64-library/2.11'

package 'rJava' successfully unpacked and MD5 sums checked

The downloaded packages are in
        C:\Users\Stephen\AppData\Local\Temp\Rtmpcy0hAb\downloaded_packages
>
install.packages('C;\Users\Stephen\AppData\Local/Temp/Rtmpcy0hAb\downloaded_
$
Error: '\U' used without hex digits in character string starting "C;\U"
>

So, obviously, at this point I am attempting something that R does not like.

You failed to install an appropriate Java version.
