[R] Combing

[Matthew Dowle]

Val,

Type "combine two data sets" (text you wrote in your post) into 
www.rseek.org. The first two links are: "Quick-R: Merge" and "Merging data: 
A tutorial".  Isn't it quicker for you to use rseek, rather than the time it 
takes to write a post and wait for a reply ?  Don't you also get more 
detailed information that way too ?

You already received advice from others on this list to look at 
www.rseek.org on 26 Oct,  package 'sos' on 27 Oct, and to 'read the manuals 
and FAQs before posting' on 5 Nov.

This month you have posted 3 times : "Loop", "Renumbering" and "Combing".

References :
1. Posting Guide headings : "Do your homework before posting" and "Further 
resources"
2. Contributed Documentation e.g. 'R Reference Card' by Tom Short 
http://cran.r-project.org/doc/contrib/Short-refcard.pdf.
3. Eric Raymond's essay http://www.catb.org/~esr/faqs/smart-questions.html. 
e.g. you posted to r-help 10 times so far,  9 of the 10 subjects were either 
a single word, or a single function name.
