Folks,
the relevant thing you have to remember is: All the stuff must be valid
R syntax (with few additional functions as mention in the ?plotmath help
file). Knowing that it is obvious where additional "operators" are required.
Best,
Uwe Ligges

Thanks to both David and Sarah. I'm glad I asked, as I had tried some of
the combos Sarah suggested and observed the same behavior, which puzzled
me. David, thanks for reminding me about ~ as that is a different way to
get a space into the string. I just don't use plotmath often enough to
become decent at it. Thanks again. Bryan

Hello R Masters and the Rest of Us:
The first of these works fine, the 2nd is accepted but too literal
(the "%->%" is shown in the plot label and in the wrong position).
The 3rd throws and error due to "unexpected SPECIAL". Would someone
recommend a way to format this? I want the two phrases connected by a
right arrow.
TIA, these things always elude me. Bryan

xlab1 <-expression(paste("Phase Angle ", phi, " Neat-O"))
xlab2 <- expression(paste("treatment: low stress", "high stress", sep
= "%->%"))
xlab3 <- expression(paste("treatment: low stress", %->%, "high stress"))
plot(1:10, main = xlab1)
plot(1:10, main = xlab2)
Doesn't seem that %->% "works" without flanking terms
xlab3 <- expression(treatment*":"~low~stress %->% high~stress)
plot(1, main=xlab3)
Or:
xlab3 <- expression("treatment: low stress" %->% high~stress)
plot(1, main=xlab3)
