Hi,
I appreciate your help with the segmented function. I am relatively new to
R. I followed the introduction of the 'segmented'-package by Vito Muggeo,
but still it does not work.
Here are the lines I wrote:
data_test<-data.frame(x=c(1:10),y=c(1,1,1,1,1,2,3,4,5,6))
lr_test<-lm(y~x,data_test)
seg
We really need the small reproducible example requested in the posting
guide, including sample data, the actual R commands you used, the
libraries required, and your OS and version of R.

Hi there.
Here's the error message.
Error in seg.lm.fit(y, XREG, Z, PSI, weights, offs, opz) :
(Some) estimated psi out of its range
I have tried many ways to specify the arguments, but apparently the error
message is related to the estimated break point being invalid. However, my

dear Phil,
I am not able to read the error message.. did you forget it?
However: does x exist in the workspace?
The following lines work:
myreg2 = lm(y ~ x, data=xy)
mysegmented = segmented(myreg2, seg.Z=~x, psi=c(245000))
myreg2 = lm(xy$y ~ xy$x)
x<-xy$x
mysegmented = segmented(myreg2, seg.Z=
Hi everyone.
I'm trying to use the segmented function with the following data:
For instance, I use segmented package as follow:
myreg2 = lm(xy$y ~ xy$x)
mysegmented = segmented(myreg2, seg.Z=~x, psi=c(245000), control =
seg.control(display=FALSE))
Which get me to the following error :
