Dear XpeRts,
I prepared a no qoute Character string by the following command
s<-noquote(paste (b1, collapse=","))
where, b1 is the vector of 24 intergers.
> dput(b1)
c(1L, 2L, 6L, 7L, 12L, 16L, 17L, 20L, 21L, 23L, 25L, 34L, 46L, 48L, 58L, 64L,
65L, 68L, 82L, 97L, 98L, 101L, 113L, 115L)
> dput(s)
structure("1,2,6,7,12,16,17,20,21,23,25,34,46,48,58,64,65,68,82,97,98,101,113,115",
class = "noquote")
I want to use "s" in the following command
matb1<-res[,c(s))]
The objective is to call those columns of matrix "res", whose numbers have been
defined in "s".
But when i plug "s" into "matb1" i get the following error
Error: no 'dimnames' attribute for array
How can i get rid of it??
thanks in advance
Eliza
