i've just installed the package"xlsx",which is used for read,write,format
Excel 2007 files, as i loaded the package ,i was told to intall the package
rJava, the problem was that i didn't have a JAVA platform on my computer, so
i have to install JAVA JDK first, my problem is ,after i 've installed
JDK,how can i make my JAVA available for R use,the manual said(quote) NOTE:
You may need to add to your PATH variable the location of your JVM (e.g.
C:/ProgramFiles/Java/jre6/bin/client) to get rJava working.
how can i set the PATH variable ?
