How to Build matrix in R -

-

i have samples a:z , want make matrix have sample column , value column 1's.

result should this.

samples values        1 b        1 c        1 d        1 .        . .        . z        1

use cbind create matrix

 cbind(samples, values=1)

but matrix can hold single class output columns 'character'

i suggest use data.frame hold columns of different class.

 data.frame(samples, values=1)

if want 'samples' column character class, use option stringsasfactors=false. default true.
