Is it possible to change the fill color of a point? For example, the outer
color being "Blue" and inner color being "Grey".
I've tried changing "col" and "bg", but that does not seem to have the desired
effect.
Below is another attempt, but the pixel resolution of the points function does
not appear to be high enough for this to work:
figure_file_name_and_path<-paste("Test.wmf", sep="")
vals_200<-rnorm(200)
vals_201<-rnorm(200)
win.metafile(file=as.character(figure_file_name_and_path), pointsize = 10)
plot(-4:4, -4:4, type = "n")# setting up coord. system
points(vals_201, vals_200, col = "blue", bg = "white", pch=19, cex =1.7)
points(vals_201, vals_200, col = "grey", bg = "white", pch=19, cex =1.5)
points(rnorm(100)/2, rnorm(100)/2, col = "blue", bg = "white", pch=19, cex
=1.5)
dev.off()
As a second question, is there any way to increase the pixel resolution of the
points produced on the plot so that they are perfect circles. I just noticed
that the fill does not perfectly fill the points on the plot and there are some
pixels outside the circle.
Thanks again.
