[R] the first name of the first column

[Bert Gunter]

Clarification needed.

Are your data in a data frame or an alphanumeric matrix? What does it look
like?

A small reproducible example would be very useful here I think!

Also, is this relevant:

> d <- matrix(1:12,ncol = 4)
> d
     [,1] [,2] [,3] [,4]
[1,]    1    4    7   10
[2,]    2    5    8   11
[3,]    3    6    9   12
> dd <- d[,c(3,1,2,4)]
> dd
     [,1] [,2] [,3] [,4]
[1,]    7    1    4   10
[2,]    8    2    5   11
[3,]    9    3    6   12

Perhaps you neeed to spend time with an R tutorial that covers indexing of
data frames and matrices, an absolutely basic R operation? (I am not clear
from your question if this is your problem).


Cheers,
Bert
