Somehow, I don't get how the labels of Hmisc work. My
expectation was that if I use the following code and
then the print method, I would get an output where the
headers are replaced by the labels but I get the
normal variable names. How can I get the labels as
headers instead in the printed table?
That's perfect! The subset way is very easy to use and
I have to play around a bit more with label() which
seems quite complex.
Thanks a million,
Werner

Try this:
mydf <- data.frame(s8v2=rnorm(10), s12v3=runif(10), s1a5=rnorm(10),
s6v1=rnorm(10))
pos <- match(c('s8v2', 's1a5'), names(mydf))
mydf[,seq(pos[1], pos[2])]

Thank you very much, Henrique! The comment function is
exactly what I was looking for.
Regarding 1) why example was bad: The column names
don't follow an easy pattern but are more like "s8v2",
"s12v3", "s6v1" etc.
Kind regards,
Werner

Try this:
1)
mydf[1,paste("col", 4:8, sep="")]
2) You can use comment function:
comment(mydf) <- c("Column number1", "Column number2")
or
comment(mydf$col1) <- "Column number1 etc"
then
comment(mydf) and comment(mydf$col1) to see the labels

Hi,
I have two loosely related questions which could make
my live again a bit easier:
1) Is there a simple way to select a range of columns
in a data frame using column names?
I am thinking of something like mydf[1,"col4":"col8"]
2) I have a data frame with many columns and they all
have short
8 matches
