scale subsets of grouped data in data frame
.... It would be
really nice to find a more automated way.
My data looks like this
group group_height group_weight height weight
g22 3.2 8.896 3.2 8.896
g22 2.5 6.95 2.5 6.95
g22 3.1 8.618 3.1 8.618
g49 2.4 6.672 2.4 6.672
g49 4.2 11.676 4.2 11.676
g49 2.5 6.95 2.5 6.95
g55 2.6 7.228 2.6 7.228
g55 3.4 9.452 3.4 9.452
g55 3.3 9.174 3.3 9.174
What I want to do is scale the data by each group

Sorting alphanumerically
I'm trying to sort a DATAFRAME by a column "ID" that contains
alphanumeric data. Specifically,"ID" contains integers all preceeded
by the character "g" as in:
g1, g6, g3, g19, g100, g2, g39
I am using the following code:
DATAFRAME=DATAFRAME[order(DATAFRAME1$ID),]
and was hoping it would sort the dataframe by ID in the following manner
g1, g2, g3, g6, g19,

Samba on MacOSX and printing
Hi all,
an iBook running Mac OS X 10.2 recently joined my little network, so
i did configure it for using a Windows shared printer (HP Officejet G55),
naturally through SMB protocol. I used CUPS for setting it up. Now, the
problem: if i try to print from the iBook, the printer takes about 10
minutes
for throwing out each page and the document seems to be continuously spooled
up to windows. This is what i mean: when you send a job from iBook, in...
