I would like to make a suggestion for an improvement (IMHO) of ?legend.
Please add a remark that the x,y positioning coordinates are in the units of the plot() itself, *not* in pixels or anything the like.
It would have saved me a lot of time figuring out why my legend just wouldn't appear if ?legend would have told me to set the coordinates in the units of the x and y axis. I haven't found it anywhere on the list or manuals (but I may have missed something). Now that I know this, it seems a logic choice, however, refering to a 'graphics device' seems to imply a coordinate system in pixels starting from the upper/lower left of the device (the usual choice in graphical manipulations in programming languages). This assumption is false and IMHO is nowhere in FAQ/manuals contradicted.
regards, Paul

Yes, I am using plot and then lines. The legend is just not appearing. I am using the coordinates of the legend (150,4) which work on boxplot and plot. I have not looked at the output of par (I don't know how to) to see if they are in the region. I assumed if they worked for plot and boxplot they would also for lines.

When I am trying to put a legend on a plot where I am using "lines", R just
ignores it. I can do it with boxplot or plot, but just not with lines. Am I doing something wrong? Maybe I am just making a mistake?
