[R-sig-Geo] merging data with a dataframe based on a common identifier

I have used v.strahler in GRASS to calculate the stream order.  This
module writes its results to a text file.  The line column of the
output data is the common name between the two data sets.  I would
like to attach the stream order to the streams vector.  I have looked
at the data once in R with

pseudocode:
streams <- readVECT6("streams")
str(streams)

and it is a huge list.  I am not sure the best way to tackle this problem.
thanks for any help,
