Windows crash in confint() with nls fit (PR#8428)
Full_Name: Ben Bolker
Version: 2.2.1
OS: Windows XP and 2000
Submission from: (NULL) (128.227.60.124)
The following code, using confint() to try
to get confidence intervals on an nls object
that has been fitted with algorithm="port"
reliably crashes R 2.2.0 and 2.2.1 with the
latest version of MASS on a Windows 2000 and
a Windows XP machine here. I *think* earlier

I have found some "issues" (bugs?) with nls confidence intervals ...
some with the relatively new "port" algorithm, others more general
(but possibly in the "well, don't do that" category). I have
corresponded some with Prof. Ripley about them, but I thought I
would just report how far I've gotten in case anyone else has
thoughts. (I'm finding the code

I am wondering if there is a problem with the function rep(). Both the

the second did.

Pager size in 1.2.2 Windows
The following sequence of commands (for example):
>my.data<-rnorm(10000, 5, 1)
>my.data
fills my pager buffer beyond its capacity. When I type "my.data", the
pager displays approximately the bottom 7000 cells of the file, but "loses"
the first 3000. Is there a some setting that increases the size of the
pager buffer, or is this a limit in the Windows version?

How do I force confint() for glm() to be quiet?
I need confint() for glm() to supress the messages
"Waiting for profiling to be done..."
because they mess up the caching mechanism of pgfSweave (see
https://github.com/cameronbracken/pgfSweave/issues/40).
I have read the help page of confint(), but I do not know how to get
the help page for the glm() version, if any such help page exists.
Is there a general way of turning of output

Is there a way to add a legend to an image plot? I don't see any

no?). Although the documentation says image takes plot() parameters, it

Should there be a confint.mlm ?
It seems that confint.default returns an empty data.frame for objects of
class mlm. For example:
```
nobs <- 20
set.seed(1234)
# some fake data
datf <-
data.frame(x1=rnorm(nobs),x2=runif(nobs),y1=rnorm(nobs),y2=rnorm(nobs))
fitm <- lm(cbind(y1,y2) ~ x1 + x2,data=datf)

Which confint() method do you have in mind? There is at least four of
them by default in R, and many additional classes could make use of

Problem with confint function
Hi,
I am currently doing logistic regression analyses and I am trying to get
confidence intervals for my partial logistic regression coefficients.
Supposing I am right in assuming that the formula to estimate a 95% CI for a
log odds coefficient is the following:
log odds - 1.96*SE to log odds + 1.96*SE
then I am not getting the right CI.
For instance, this is a summary of my model:
