Ted,
Try this:
set.seed(54321)
X0 <- rnorm(50) ; Y0 <- rnorm(50)
# add pty = "s"
par(mfrow=c(2, 1), mfg = c(1, 1), cex = 0.5,
pty = "s")
plot(X0, Y0, pch = "+", col = "blue",
xlim = c(-3, 3), ylim = c(-3, 3),
xlab = "X", ylab = "Y", main = "My Plot",
asp = 1)
par(mfg = c(2, 1))
plot(X0, Y0, pch = "+", col = "blue",
xlim= c(-3, 3), ylim = c(-3, 3),
xlab = "X", ylab = "Y", main = "My Plot",
asp = 1)
See ?par and 'pty', which defaults to "m".
HTH,
Marc Schwartz
