write.table should provide the basic function. It is designed to write 

 write.table(crabs, file="crab.out.csv", sep=",")

... will give you a comma separated file:
... first five lines 

If you are working in Windows, and want to specify a directory, you 
need to use forward slashes in the full filename. The backslash 
character has special meaning in *NIX systems, which is where R was 

If you want to "see" the dataframe, crabs, just type the name. You 
should see 200 lines of data.
