R help - Dec 2001 - change layout of legend

Is it possible to change the layout of a legend in the plot function for a plot
that shows 4 variables, so that the legend shows the variables in a row with 4
elements instead of a column, or to have two columns and two rows in the legend.
Also I can't seem to be able to change the size of the font used inside the
legend.
Any suggestions?

1. Suggestion: Please configure your mailtool.

2. Suggestion: Read the docs for ?legend.


You'll need the following two arguments:

- ncol the number of columns in which to set the legend items 
  (default is 1, a vertical legend). 

- cex character expansion factor relative to current par("cex"). 

Example:
 plot(1:10)
 legend(5,5, pch=1:4, legend=LETTERS[1:4], ncol=2, cex=2)
