Hi,
Could anyone help me with this error? I have no idea what that is
about...
file <- system.file("DADOSCASUMCCORMICK.xlsx", package = "xlsx")
> data <- read.xlsx(file, 1)
Error in .jnew("java/io/FileInputStream", file) :
java.io.FileNotFoundException: (No such file or directory)
Is there really a file by that name in your package directory? When
I do that on my machine, file is "" after the first command, which
is the documented behavior when the file cannot be found.
My guess is that you need to provide a path and append it to the
file name before sending a request to system.file. I'm also
suggestinging that you don't really want to be saving you work files
in system directories and you should be using getwd() and paste()-
ing to your file name.
On re-reading this I see that it was unclear that I was suggesting
_not_ using system.file for this task. Just use getwd() and paste to
construct a path/file.ext.
Thanks!
