[Bioc-sig-seq] How to convert upper case strings to lower case

[Joern Toedling]

Hi Xiang,

have a look at:
?tolower

I recommend downloading an R reference card, such as this one,
http://cran.r-project.org/doc/contrib/Short-refcard.pdf
Thus you won't have to consult mailing lists for such basic questions.

Also 
www.rseek.org
can be very helpful.

Regards,
Joern
