hi list,
used versions: 2.12.1 and 2.14.0 under ubuntu and macosx.
I recently stumbled over a problem with `nls', which occurs if the model
is not specified explicitly but via an evaluation of a 'call' object.
simple example:
8<--
I get the error
Error : evaluation nested too deeply: infinite recursion /
options(expressions=)?
during a 'R CMD check ...'
on one of my packages. The reason seems to be that this package is
mutually dependent on another one (i.e. the DESCRIPTION files of package
A lists package B under "Depen
this is probably not really a R specific question, if so apologies for
off-topic posting:
I'm interested in the probability density function of the maximum values
from repeated samples of size N from a normal distribution:
smp <- rnorm(N, meanval, stdev)
with some mean 'meanval' and standard dev

dear list,
my question concerns the use of `eval' in defining the model formula
for `nls' (version 2.6.2.).
consider the following simple example, where the same model and data
are used to perform unweighted and weighted fits. I intentionally
used very uneven weights to guarantee large difference

have not followed the thread completely, but:
have you tried `bitmap' with `type = pdfwrite' (or psgrb)
for comparison? at least with `pdf' there are some issues which
can be avoided by using ghostscript via `bitmap'.

my understanding of `eval' behaviour is obviously
incomplete.
myquestion: usually `eval(expr)' and `eval(expr,
envir=parent.frame())' should be identical. why does the
last `eval' (yielding `r3') in this code _not_ evaluate in
the local environment of function `f' b

I initially thought, this should better be posted to r-devel
but alas! no response. so I try it here. sory for the
lengthy explanation but it seems unavoidable. to quickly see
the problem simply copy the litte example below and execute
f(n=5)
which crashes. called with n != 5 (and of co
