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

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

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

"sp","sex","index","FL","RW","CL","CW","BD"
"1","B","M",1,8.1,6.7,16.1,19,7
"2","B","M",2,8.8,7.7,18.1,20.8,7.4
"3","B","M",3,9.2,7.8,19,22.4,7.7
"4","B","M",4,9.6,7.9,20.1,23.1,8.2
.

.

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 developed.

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