By using indexing.  If this is a matrix called mymatrix:

mymatrix[,2] <- mymatrix[c(4,1:3),2]

If it's a data frame called mydf:

mydf$two <- mydf$two[c(4,1:3)]

See the help pages and examples...

I use either eps or pdf for inclusion into LaTeX.  You also have the fig
file format, so you can use xfig to edit before inclusion.

Two ways:
1) Install the Hmisc package, and see ?latex
2) Install the xtable package, and see ?xtable.

1) help.search("some keyword")
2) go to http://cran.r-project.org, and follow the "Search" link to search
the mail archives.
