[R] basics: how do you sort a table?

[Monica Palaseanu-Lovejoy]

Hi,

This may be a very basic question but it seems i cannot figure it 
out does not matter what.

how do you sort a table (ascending or descending) after the values 
in one particular column? I want to do something like the sort 
function in Xcel.

Also, is there any other plot function that accepts log for y axes 
like the parplot2() from gregmisc? Thanks for the tip Marc about 
barplot2. very useful indeed!

Thank you again for all the help,

Monica
