probelm solved:
data - read.table(pdvspt.txt, header = T, dec = ,)
It was the coma, now I have everything in numeric.
Thanks a lot for the support!

Hi,
thanks for your reply.
I attached the example.
I tried your suggestion:
data[is.factor(data)] - lapply(data[is.factor(data)], function(x)
as.numeric(as.character(x)))
But I still have the var as factors.
I'm thinking now, in the txt file the decimals numbers are separated with a
coma.
Hi,
Is there a way to recursively change the variables imported with
read.table(..) - and then attached with attach(..) - from as.factor to
as.integer?
I have about 9 variables that are now recognized as factors but I need to do
statistics on them so I need to change them in as.integer. It
1) Give us a reproducible example.
2) You probably don't want to use attach.
3) Yes there is a way, but without an example, it's hard to say what
will work. Assume a data.frame called df, maybe something like the
following, which is untested...
df[is.factor(df)] - lapply(df[is.factor(df)],

Hello All,
I would like to report the following bug or maybe you can explain if I am
wrong.
I am sampling from two different populations with weights. The two
populations have the same age groups and I want to distinguish where I am
sampling from. That is why I am using a matrix such as:

x - c(1.1,2.1,3.1,4.1,5.1)
as.integer((x - round(x)) * 10)
