Hi,
I write a package in Linux and ready to distribute, and I can install it in
linux and run it.
However, when I have install it in my Windows' R.
I can not 'require' it.
is.element("grt", installed.packages()[,1])
[1] TRUE
require(grt)
Loading required package: grt
Failed with error: ‘'grt' is not a valid installed package’
Is there any pitfall between platforms?
And anywhere I could check more detailed error message.
How did you install it in Windows? If you just copied it from the
Linux install directory, or if its in a shared directory, it probably
wont work.
You need to do a proper R CMD INSTALL on Windows, and for that you'll
need the assorted dev tools for building R packages on Windows.
For the record: these days you do not need any extra tools unless the
package contains code that needs compilation, and in the latter case
we provide the win-builder service.
However, the message indicates no file grt/Meta/package.rds, which
would be there if the package was copied from Linux. So we need to
know exactly what was done.
