...ld like to know which version or R was used to create a given package. I think I remember seeing that topic discussed recently but cannot find it among my notes. Can anyone tell me how to determine which version of R created a package? Thanks.

...every character with a blank. However gsub(".xls", " ", file.label) replaces ".xls" with a blank as expected. It appears that "." is some kind of wild-card.

...il Archives I discovered that ctrl L will clear the Rgui screen, which is what I'd like to do from a print (or some similar) statement.

...able to avoid defining the variable "par" and then specifying each of its elements, but all my attempts resulted in a list whose first element is a list, rather than the elements of the list.

...o the R code produced no unexpected results. Is there a way to record my mouse movements and mouse clicks, as well as keyboard entry, in a script, so that I can just watch to see if all unfolds correctly? Many thanks for any suggestions.
