Not much of a definition...no body???
and I want to title the plot after I invoke the gaussian_simulation
function
sim.res<-gaussian_simulation(p=3, r=4, q=3, c=0.1,d=2,
Wchoice = "avg",
pre.scaling = TRUE,
oos = TRUE,
alpha = NULL,
n = 100, m = 100, nmc = 100)
plot(sim.res)
title("p=3, r=4, q=3, c=0.1,d=2")
The following assumes you want the values of those parameters for the
title to be picked up from the function's arguments, because the code
you offer for the title is syntactically correct. You first need to re-
read Bill Venables response regarding bquote which you show no signs
of adapting, and then you need to study:
?plotmath
... where you will learn the proper syntax for "=" ("==") and for
comma-separated lists. You should not need the quotes inside the
bquote call. The "~" (space) and "*" (no space) are syntactic
separators inside expressions (in the limited scope of the plotmath
perspective). The plotmath interpretation of these is not well
described in the documentation (IMO). The help page could easily lead
you to think that commas or spaces might be valid separators, or that
list() was the same as list() in regular R, and it's only by repeated
errors and reading worked examples on r-help that I have learned
otherwise.
Consider this and apply lessons learned:
plot(1,1); p=3; r=4; q=3; c=0.1; d=2
title(main= bquote( list(p==.(p), r==.(r), q==.(q), c==.(c), d==.
(d)) ) )
# you might get away with not using the "main" argument name, but I
think it's bad practice.

What I want to do is put the arguments I supply to a function into
the
title of a plot
Say I'm calling func.1
func.1(a=4,b=4)
plot(....,..., title("a=4, b=4"))
If I'm calling func.1 with different arguments, I want the plot
title to
reflect that.
A small detail is that func.1 might have an argument with a default
like
c=a+b. I tried using expression but couldn't get it to work.
Is there a way to do this using expression() ?
