I retract the siggestion I proposed last night -- it was based
on a bad hunch! Sorry for wasting time.
Best wishes,
Ted.

Dear R-users,
I have the following data
x - runif(300,min=1,max=230)
y - x*0.005 + 0.2
y - y+rnorm(100,mean=0,sd=0.1)
y - y%%1 # --- modulo operation
plot(x,y)
and would like to recapture the slope (0.005) and intercept(0.2). I wonder if
there are any clever algorithms to do this. I was

Hi,
I do not know the intercept and slope.
And you have to know them in order to do something like:
ix-(y 0.9*(x-50)/200
I am right?
cheers

Although I really knew them from the way you generated the data,
I pretended I did not know them.

Ted,
I agree with you that if you unwrap the data you can use lm.
And you can separate the data in the way you describe. However, if you
have thousands of such datasets I do not want to do it by looking at
the graph.
Yes the scatter may be larger as in the example and range(y) may be
larger
