[R] Ajdustment of data symbols

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"), 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!
