write.csv

If you don't want the row names, as 'write.csv()' writes out by default,
try

write.table(<object>, file = "myfile.csv", sep = ",", row.names = FALSE)
Or, better (since it sets other args to the appropriate values),

write.csv(<object>, file = "myfile.csv", row.names = FALSE)

That write.csv supports row.names = FALSE is explicitly mentioned on the 
help page.

hallo,

i have a problem by writing a csv file
the first colum is filled with index numbers from 1 to n.
i have to unique two csv files once a week while one file is always the
same.
can anybody tell me, how to write the dataset into a csv file without the
first row of the indexnumbers.
x[,-1] does not wok as it eliminates the first "interesting" colum.
col.names is not accepted by r (do i habe to start a package first? which
one?)

thx

sven
