Hello,
Fitting a piecewise smooth curve to a set of points (and a piecewise
linear function in particular) seems to be a recurring question on
this list. Nevertheless, I was not able to find an answer to a
question that bothers me.
Suppose I have the following data set, and would want to fit it w
Hello everybody,
Is it possible to coax legend() into displaying more than one simbol per
line in legend? I have a graph like the one attached to this mail; I would
like to reorganize the legend in such a way that the duplicate text would be
omitted, i.e., the first line would read "increasing

Thank you. I guess using predict() is probably closest to the R philosophy.
All the best,

Dear all,
Here I come with another stupid question. Suppose I want to use nls()
to fit a series of data (here modelled by generated points), then plot
the points and the fitting curve. I figured out some way of doing it:
x <- runif(1:20, 0, 10)
y <- 0.1*x^2 - rep(3, length(x)) + rnorm(length(x),
oma etc. may be interesting for you. And for the relation between

Hello everybody,
I am sure this is a beginners' problem which is being asked
recurrently every few months, but nevertheless I wasn't able to find
the answer searching through the r-help list.
So here is my problem: I would like to plot a set of points (y vs. x),
a (linear) regression line through
