Hello,
Is there a way to specify a non-default adjustment for data symbols, similar to
what "adj" does for text?
For example, the following lines of code produce a red triangle on the bottom
border of the plot:
plot(0, 0, type = 'n', xlab = "", ylab = "")
points(0.25, par("usr")[3], pch = 17, col = "red", cex = 2,
xpd = TRUE)
I would like to draw the triangle completely outside the plotting area, with the
upper vertex touching the x-axis...
Thank you in advance!
Best,
Giovanni

Try this. The par("cxy") gets a vector of character width and height
in user coordinates.
points(0.25, par("usr")[3]-par("cxy")[2]/2, pch = 17, col =
"red", cex = 2, xpd = TRUE)
