Hi,
Good idea, what do you say we try and write a page on this in the R
wiki?
I started the topic:
http://wiki.r-project.org/rwiki/doku.php?id=guides:overview-data-manip
Once the content is there, it wouldn't be much of an effort to create
a reference-card format if required.
Best wishes,
baptiste

Majority of questions on this list concern data manipulation. Many
are repetitive. "Overlooking" like that will always happen unless
some comprehensive data manipulation documentation is made.
I think many people would benefit if a specialized data.manip
ref.card were conceived.
Tom Short's card is an excellent one but it does not cover high
level packages like plyr, reshape, DoBy, and a few base data.manip
functions are not there as well.
Vitalie.
