[R] ref card for data manipulation?

[baptiste auguie]

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
