Wow! I hadn't meant to set off such an email flurry... Tbh all I wanted to do
was to label some plots for my own recording and notes so Bert's idea was more
than adequate. On the other hand it's instructive to venture further into the
R-universe in such distinguished company...

Hi,
Ok, some additional tweaks.
Relative to Bert's pointing out the aesthetic issues, certainly, those are
attributes that can be adjusted as Nick may require. I was focused more on the
primary issue. Using "..." is an easy way to pass additional parameters to
plot.default() as Bert indicated.
These look like very fragile suggestions. Allow x^2 to be an argument
(named expr, for example) to plotFx, don't force a user to write a
function in a very particular way. Then use deparse(substitute(expr))
in the title.

Well, if you want to do it this way, note that as written, the y axis
default label isn't "nice," and you should anyway allow for additional
graphical arguments (either way). Also, slightly better I think is to use
the built-in access function, body():
plotFx <- function(x, fun, ...) {
plot(x,
Hi,
Sorry for the misfire on the first attempt.
After seeing the clarifications, I thought about a possible way to do this,
perhaps a little more simply, while encapsulating the plotting in a function:
plotFx <- function(x, fun) {
plot(x, fun(x), main = paste0("Plot of y = ", deparse(fun)[2])
Yes, plot(z,y,..)

Thanks Bert, that is exactly what I wanted. I think that you meant plot(z,y...
in the last line?

... and if you wanted too streamline the process, something like the
following could be encapsulated in a function:
fun <- quote(exp(x))
z <- 1:9
y <- eval(fun,list(x = z) )
plot(x, y, main = paste("Plot of y =", deparse(fun)))

Thanks but that's not quite what I meant
I am trying out different functions and they don't necessarily vary in a
regular way (like say all being powers of x where it'd be simple to just have a
vector for the powers you want)
So I might have
y<-x^2
y<-cos(x)
y<-exp(x+1)
What I am after is a way o
The well known deparse(substitute(...)) construction.
plot(1:9, main = paste("plot of",deparse(substitute(y <- x^2

Hi,
See ?plotmath
A
Is there any way of taking a line of r code (eg y<-x^2) and pasting that line
of code, as is, into a label, so that for example I could then have a plot
label "Plot of y<-x^2"?
Thanks Nick Wray
