NLS question:Quadratic plus plateau fit
Dear R colleagues:
Am trying to fit a simple NL model to determine Economical Optimum Nitrogen
Rates.
The segmented (quadratic + plateau) model only works with some y's, in some
cases I get a "singular gradient" error.
I'll appreciate any ideas in how to solve the singular gradient error.
Thanks,
Jose

Quadratic curve on a loop
Dear R community, once again I request your generous help on an R issue
I cannot seem to figure out.
I am trying to do some analysis for multiple sites, in my example I am
using only two, but the same will done on many sites. It's just ONE
line, so I hope somebody can give a me a hand by email.
Look at the loop to make the plot x ~ y. If the curve function is
removed from the loop

Getting the R squared value in asymptotic regression model
Please help getting the R squared value in asymptotic regression model
I use the code below
model1<-nls(GN1~SSasymp (nrate,a,b,c), data = data.1 )
and R produced the modell coefficients without the R squared value?

Looking for better fax handling
I am having troubles with sending faxes. I hope someone can help me
work out a better method.
Basically we have a special address that our users can send to. It
winds up on our Asterisk server which runs a Python script that parses
the message for attachments and the phone number from the recipient
address. The attachments are converted to TIFF and stored in a folder
with various information
