[R] Extracting "row.names"

I'm trying to extract the row names of a table I have read into R.
> data <- read.table("mesodata.txt", header=TRUE, row.names=1)
When I try to extract them using,
> names <- data$row.names
I've tried changing to a matrix, data frame, etc. and still get "NULL".
I've checked ?row.names as well as help on extracting part of an object,
etc. and unless I'm missing something obvious (likely), I can't figure out
how to extract them.
I want to extract the row names (which are basically gene id's) as well as
some other columns (which I can do successfully) and "cbind" them into
another data frame (which I can also do successfully). I just can't get the
row names extracted (Assigned) to an seperate object.
Any suggestions would be appreciated.
