Dear group,
I experience some problems with gam() function after R update to
version 2.13.1
The function in both gam and mgcv packages stopped to work. Before,
with the same code I used, everything was fine.
Reports like this often turn out to be inaccurate because either the
(not offered) code was not the "same" or the (also not offered) data
was different. Did you reinstall these packages? How? How many
versions "up" was the update? sessionInfo()?
The function from gam package yields following warning:
Residual degrees of freedom are negative or zero. This occurs when
the sum of the parametric and nonparametric degrees of freedom
exceeds the number of observations. The model is probably too
complex for the amount of data available
That certainly looks like an informative error message. What do you
want us to do about it?
while gam() from mgcv crashes R.
A report of a real "crash" should go to the package maintainer with a
lot more detail than you have provided above.
Did I miss something?
Perhaps reading the Posting Guide?
Thank you in advance.
PJ
