You can use the grconvertY function to find the position in the current user coordinates that corresponds to the top of the device area (instead of using locator).
Thank you very much. grconvertX() and grconvertY() work very well.
Look at the "merge" argument to the legend function.
I gave "merge = FALSE" in the command. It gave the result like: ---o However, I hope to get something like: --- o or o --- (I prefer to this one) There should be a space between the point and line. Thanks again. Regards, Jinsong

Now, I use a stupid solution, I replace "top" in the above command with locator(1). However, using this solution, the plot have to be in an interactive mode, and the position is not accuracy. 2) the point is connected with the line in the legend. I hope there is a space between the two symbols, like --- o instead of ---o. If possible, put the point before the line, like o ----. Unfortunately, I don't find any way to do that. Any suggestion will be greatly appreciated.
