Hi
Why scratching your left ear with your right hand?
If M is numeric matrix
d.m <- data.frame(M)
names(d.m) <- paste("Rep", 1:dim(M)[2], sep="")
not sure what you want as row names as var is not defined anywhere in your
code, but you can use the same principle for changing row names. Jus use
row.names(d.m) <- whatever vector of names you can elaborate

BTW. R is not C and you shall use strong features of R not to try to avoid
them.
