Hi, all:
Is there an automatic smart legend for R?
Since my R code is running in a row, which will produce a bunch of R plots
in a single run, some of the produced plots are really "ridiculous".
Because my legend is fixed to "topleft", sometimes, which occludes the key
parts of the figure/plots, but most of the time, the legend works just fine.
I'm wondering is there a smart legend in R? Whenever I set "topleft" but
occlude the actual plots, the smart legend may reset from "topleft" to
"topright".
Or, just try "topleft", "topright", "bottomleft" and "bottomright" in a
particular sequence, and calculate the occlusion ratio.
Pick up either the legend with the least occlusion, or the first priority
legend when some legends are of the same occlusion?
Hi JIA Pei,
The "emptyspace" function in the plotrix package may be helpful. This
tries to find the largest empty rectangle on a plot and returns the
coordinates of the center of that rectangle.
Jim
