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)
