Minor correction -- omitted comma. Should be:

   write.table(t[ , c("a", "b", "c")], row.names=FALSE)

Also, using the name "t" should be avoided, because "t" is a built-in function: t()

Try:

write.table(t[c("a", "b", "c")], row.names=F)

 Hi
 I'd like to write.table a dataframe, but with an specific order of
 columns. Is there a direct way to do it? or I have to generate a new
 dataframe as follows:

 t  <- data.frame(c=1:10, b=11:20, a=letters[1:10])
 t2 <- data.frame(a=t$a, b=t$b, c=t$c)
 write.table(t2, row.names=F)

 Thanks for any comment

 Juli
