I am currently using R on a Windows 10 laptop.
I have downloaded an xlsx file in the working directory. After loading the xlsx package, whenever I am trying to read the file using the read.xlsx, it is showing me this error :
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, : java.lang.IllegalArgumentException: Your InputStream was neither an OLE2 stream, nor an OOXML stream
What can I try to resolve this?
