Dear R-users,
I'm trying to add a title on a plot with both mathematical notation and values substitution. I read the documentation and search the mailing list but I was not able to solve my problem. Actually, there is a message by Uwe Ligges on June 2003 which addresses a question very close to mine, but the code provided doesn't work. The code is the following:
# I add this to let you run the example by copy and paste
t1 <- 0.5; len <- 1
# then
plot(1:10,
main = substitute("Monotonic Multigamma run (" * n == len * ", " * theta == t1 * ").", list(len = len, t1 = t1)))
but I got the following:
Error: syntax error
I also tried with just one value substitution:
plot(1:10,
main = substitute("Monotonic Multigamma run (" theta == t1 * ").", list(len = len, t1 = t1)))
which works fine. How can I have more than one value substitution, together with mathematical notation and text?
Thanks in advance for any reply.

Luca,
I believe you need paste in this instance:
t1 <- 0.5; len <- 1
plot(1:10, main = substitute(paste("Monotonic Multigamma run (", n == len, ", ", theta == t1, ").", sep = ""), list(len = len, t1 = t1)))
