Read The Fine Manual... the document "An Introduction to R" is supplied with R,
and section 10 discusses functions. (Macros are not supported.) Depending on
what you want to parameterize, a review of indexing and lists (section 2.7,
5.3, and 6) is likely to be needed as well. This is a valuable document to be
familiar with, though I recommend avoiding the use of attach/detach discussed
in 6.3.2.
