Well, what is `Xcel' and what is a `table'?  What Excel calls sheets are
usually represented as data frames in R, and ?order will tell you how to
do this.

help.search("sort") would surely have got you there -- did you try it?

Look at `log' under ?par.  Almost all basic plot methods do. (It seems an
oversight that barplot does not.) This is in an `Introduction to R', for
example -- have you read that yet?
