Hi Frank;
Do you realize that some portions of your Nabble postings are not
being communicated to the ordinary mail-clients? This code did not
appear in my copy from Nabble. I didn't cut anything. This appears in
Nabble when you look there:
> d <- data.frame(a=1:2,b=3:4)
> label(d, self=FALSE) <- c('A','B')
> contents(d)
Data frame:d 2 observations and 2 variables Maximum # NAs:0 Labels
Storage a A integer
b B integer
I observed and noted that was happening in a prior message. The
missing formatted Nabble studd also comes across without linefeeds
when pasted, so I added some of those back in.

My function here works fine. But just for learning purposes, I'd
like to
be able to avoid the loop...
with.labels <- function(x, labels=NULL, csvfile=NULL) {
if(!is.null(csvfile)) labels <- read.csv(csvfile, sep="\t", header=F,
stringsAsFactors=F)[,1]
for(i in 1:length(x)) label(x[,i]) <- labels[i]
if(length(labels) != length(x)) cat("Warning: data and labels are
not of
same length\n")
return(x)
}
Thanks
