Subject: [R] NULL column

Hi,

I have a dataset where the first column has no name.

I would like to assign a name to this column to be able to use it

something like:

Cap <-  NULL


How can I do this?

                    beta0           beta1              pvalor        Crom
rs17      158.5980 12.252462 9.083193e-135        1
rs46      163.3730  3.304276  3.279925e-06           1
rs63      162.7924  2.084678  5.023893e-06           1
rs24      162.4252  1.837208  5.509042e-06           1


How can I do this?


Thanks,
