[R] concatenate data frame

[Don MacQueen]

Having no idea what the object "no" is, or what the object "off_set" 
is, it is difficult to understand what you are trying to do. Perhaps 
if you substituted simple numbers in the example, such as

    tab[ 1:5, 15]

it would be easier to understand.

Perhaps what you really want is cbind() or rbind(), not c().

Probably, it would be better to use ncol(tab) rather than length(tab).
