Thanks, Jean. I've actually looked at that source before. The issue is that I
can't constrain the slope of the /center/ section to be zero - in fact, I've
applied similar code to a three-segment regression and I can get a zero
slope either of the two sides, but not in the middle.
Here's a list of
ipt with simulated data and my first attempt at fitting the
model. You should be able to copy, paste, and run it. Thanks in advance.
Drew
# three-piece segmented regression
# center section constrained to slope of 0.
# simulate and plot data
T<- 1:100
energy<- 100+75*pmax(55-T,0)+25*pmax(
ut why the
documentation has all of a sudden stopped working? Alternatively could the
same thing be done at the command line forcing the user to acknowledge the
issue and either progress with the install or first restart?
Thank you for any help or insights into this problem

How to correctly input the mean equation in the 'external.regressors='
parameter is beyond me. Also, I don't know where my actual data fits in here as
this is just a framework without any identification of the data.
Can anyone help?

sue no longer than a week ago. Any help you can offer would be
much appreciated.
Thanks,

can loop
through i:n for x and it will pull out the right variable. This is a bit of
a waste of time for 3 but I want it to do bigger sets and sets of different
lengths so I don;t have to keep recoding it.
Any advice would be much appreciated,
Cheers,
Drew

Hi there I am new to R, and I was hoping you guys could help me out. I
want to make a vector that is: vec(1,2,3,4,5,6,7,8,9,10) and i want to
create a function called PercentileFinder, that if i plug in
PercentileFinder (vec, .9) it will give me 9. Creating the function is my
biggest hurdle pleas

is to use
sapply(), like this
fits <- list()
sapply(1:N,function(i){
dataset <- generateDataset(i)
fit[[i]] <- try( memoryHogFunction(dataset, otherParameters))
})
I'm assuming above that you want to save the result of memoryHogFunction
from each iteration.

Thank you.

Thanks to all who replied so quickly.
Installing liblapack-dev solved the problem and I can now install
