R help - Dec 2003 - Sampling

UseRs,

I imported a table using "read.table". It has 209 observations, I want
to
select a sample with 106 observations.  What function I use?

thanks.

sample(), of course. See the help page (?sample) for the details and the options
(with or without replacement). I guess you want something like:

DF[sample(1:209, 106), ]

where DF is your imported table.

YourData[sample(209,106),]
