Yesterday we moved to Windows 7 in our company, and also updated the java packages, as well as R (up to 2.14).
Then I tried to download the xlsx package because I rely heavily on it, but I get the following error:
Error : .onAttach in attachNamespace()
Error: .jnew("org/apache/poi/xssf/usermodel/XSSFWorkbook")
I tried the following, but this did not work:
Sys.setenv(PATH=paste(Sys.getenv("PATH"),"C:\\Program Files (x86)\\Java\\jre6\\bin\\client",collapse=';'))
options(java.parameters = "-Xmx1000m")
Since I never work with java, I have no idea what I can do. Could you help me?
Thank!
