mp3 plugin for Rythmbox or Totem?
Can anybody please suggest a suitable plugin to enable playing of mp3
files with either Totem or Rythmbox. Both of these come as part of the
CentOS 5 package, but strangely neither has the necessary plugin for
mp3, which surely is a common enough format in the music world?
Thanks,
Andy

Media formats
Is CentOS held to the same philosophy as Fedora by NOT including apps
to play formats such mp3 etc.
If this is the case, how easy is it (looking for a how-to url) to add
things such as gstream-bad to a Cent install.

Best regards,

Having trouble converting a dataframe of character vectors to factors
R Experts,
I have a dataframe made up of character vectors--these are results from survey questions. I need to convert them to factors.
I tried the following which did not work:
scs2<-sapply(scs2,as.factor)
also this didn't work:
scs2<-sapply(scs2,function(x) as.factor(x))
After doing either of above I end up with
>str(scs2)
chr [1:10, 1:10] "very important" "very
