Hi everyone.

I have a quick question regarding the look of my legend in my plot.  
As you
can see in the next figure, I have 3 series.

However, I find rather difficult to differentiate the series 1 and 3
according to their line type (lty). I would like to know if it was  
possible
to make the line type in the legend to appear more clearly. For  
example, to
give more horizontal space each side of the symbols "square" to  
have a
better idea of the line type.

t (perhaps) you could emphasize the line compenent by increasing cex  
which affects all components and at the same time decrease the point  
size. E.g.:

legend( ..., cex=1.5, pt.cex=0.8, cex=1.5, pt.cex=0.8, ...)

As always____>
