Method 1: Use latex in package Hmisc. It is VERY flexible, and works for me in
most cases.

Hint 1: "\" rarely works in R as in C, it must be escaped to "\\"

Hint 2: To increase you changes of getting a reply, always provide a full
example generating the sample data. For example, in most cases "Adam" will be
stored as a factor in the dataframe, which make things a bit more tricky. I used
I() to avoid this in the example below

d = data.frame(name=I(c("Auer","Caesar")),
               vname=I(c("Dieter","Karl")),age=c(10,30))
for (i in 1:nrow(d)) {
  d0 = d[i,]
  cat("\\MyNiceCommand{",d0$name,"}{",d0$vname,"}{",d0$age,"}\n",sep="")
}

You may nest this with sink, or better use the file argument in cat, don't
forget append.
Or directly use Rweave, which should not be too difficult for a LaTeXer, and
does not require the sink stuff.
