"copyFile"(srcPathname, destPathname, skip=FALSE, overwrite=FALSE, ..., validate=TRUE, verbose=FALSE)file.path(destPathname, basename(srcPathname)).skip is TRUE, then no copying is
attempted and FALSE is returned (indicating that no copying was made).
If such a file exists, both skip and overwrite are FALSE
then an exception is thrown.
If a destination file exists, skip is FALSE and
overwrite is TRUE, then it is overwritten and TRUE is returned.
If the copying/overwriting failed, for instance due to non sufficient
file permissions, an informative exception is thrown.file.copy().
Non-named or unknown arguments are ignored.TRUE, validation of the copied file is applied,
otherwise not.Verbose.logical indicating whether a successful file copy was
completed or not, or equivalently. In other words, TRUE is returned
if the file was succesfully copied, and FALSE if not.
If an error occurs, an informative exception is thrown.
If the error occurs while renaming the temporary file to the final name,
the temporary file will remain in the destination directory.
If the source and destination pathnames are the same, it is not safe to copy (which can lead to either corrupt or lost files) and an informative exception is thrown.
If (and only if) the file is successfully copied and argument
validate is TRUE, then this method also asserts that the
file size of the destination matches that of the source, otherwise
an informative exception is thrown.
