Hi,
Is it possible to assign a separate colour for comments written with #,
eg:-
#this is a comment
. I am looking to colour them differently from the program text in
R-Editor (not console). Is it possible to do so?
Eg. In Visual basic, the colour for remarks gets green automatically

Dear Aleksi,
there are other approaches you could consider: using nls or gnls (in the
package nlme):
m1 <- nls(y ~ a[group]*x^b[group], start=list(a=c(1, ..., 1), b=c(1, ..., 1)))
or
m2 <- gnls(rate ~ a*x^b, params=list(a~group-1, b~group-1),
start=list(a=c(1, ..., 1), b=c(1, ..., 1)))

I find sprintf() useful for this.
Compare
lab <- rnorm(8)
plot(1:10)
text(2:9, 2:9, lab)
with
lab2 <- sprintf("%4.2f", lab)
plot(1:10)
text(2:9, 2:9, lab2)

Hi there,
I want to figure out how to plot means, with 2 decimal places, of any Y
variable on a scatterplot according to any X variable (which obviously
should have limited scope). I already figured out how to plot the

Hello,
I would like to find all objects of a particular class. Is that possible to

Check out the subset= argument to nls, e.g. to regress Sepal.Length
on Sepal.Width separately for each Species using the built in iris data set:
f <- function(s) nls(Sepal.Length ~ a*Sepal.Width, data = iris,
start = c(a = 1), subset = iris$Species == s)

so you need save(list=newname, ...).

I don't know what exactly you want the program to do. But if you want to let
the function to return several values in the same time, you have to put them
into a list. E.g. in the following program, the function will return 4
different things, x and y are vectors, prob is a matrix and p
It is not clear from your post what changes per-group. If only the
starting values change (but the data and the model structure are the
same), then you can just store the starting values you want to use for
each group in a list, and then index into this list in your call to nls.

Dear Prof. Brian Ripley,
You are absolutely right. The warning message in R for my Chinese Windows

that exact in the meanings.
Thanks very much.
