Read table from clipboard into R

This awesome function is from the psych package.

read.clipboard              package:psych              R Documentation

shortcut for reading from the clipboard

Description:

Input from the clipboard is easy but a bit obscure, particularly
for Mac users. This is just an easier way to do so.  Data may be
copied to the clipboard from Exel spreadsheets, csv files, or
fixed width formatted files and then into a data.frame. Data may
also be read from lower (or upper) triangular matrices and filled
out to square matrices.

Usage:

read.clipboard.upper(diag=TRUE,names=FALSE,...)
