The R Administration and Installation manual explains this nomenclature. OP _is_ typically using two libraries... the one installed with R and the "personal" library which contains the packages installed by the user. You retrieve packages from libraries using library(somepackage)
Of more relevance here is the fact that OP has yet again failed to read the Posting Guide, and appears to have attempted to send a disallowed attachment type through the mailing list and it has been removed from the message. Ordinarily I would recommend trying to use dput() to remove the need for the file, but in this case it may be best for the OP to send a link to the file stored on a file sharing website. In any event, making the example reproducible is the responsibility of the p person asking the question. I highly recommend reading [1][2] and using [3] to verify that the plain text example actually runs up to the point where the error occurs.
