[R] rJava not loading on Windows

[Henrik Bengtsson]

Hi,

I've successfully used it on a Linux setup, but when I try to load
rJava on Windows 7 64-bit (session info below) I get:

% R --vanilla
> library("rJava")
Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dirname(this$RuntimeLib)
  error: a character vector argument expected
Error: package/namespace load failed for 'rJava'
> traceback()
2: stop(gettextf("package/namespace load failed for %s", sQuote(package)),
       call. = FALSE, domain = NA)
1: library("rJava")


For the record, I have Java SDK installed and on the PATH:

> Sys.which("javac")
                                            javac
"C:\\PROGRA~1\\Java\\JDK17~1.0_0\\bin\\javac.exe"
> system("javac -version")
javac 1.7.0_02

> Sys.which("java")
                                            java
"C:\\PROGRA~1\\Java\\JDK17~1.0_0\\bin\\java.exe"
> system("java -version")
java version "1.7.0_02"
Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
Java HotSpot(TM) 64-Bit Server VM (build 22.0-b10, mixed mode)

I'm sure there is at least one other Windows user who bumped into
this.  Any suggestions how to fix/troubleshoot this?

Thanks,

Henrik
