%I have a quick question which is probably very simple.

%I have a data frame, and want to sort the data by putting one column in to 
%ascending order 
%
%i.e                becomes
%A  B                A   B
%1  0.5               3  0.4
%2  0.9               1  0.5 
%3  0.4               4  0.7 
%4  0.7               2  0.9 
%
%I can't seem to find anything in the help about sorting data frames.

foo[order(foo[,"B"]),] ?

%Many thanks
