dotchart.R and left margin
Hello,
In trying to minimize the margin on the left hand side when using
dotchart I found what may be a typo in the code.
In the lines below from dotchart.R, should nmai[4L] be nmai[2L]?
if (!(is.null(labels) && is.null(glabels))) {
nmai <- par("mai")
nmai[2L] <- nmai[4L] + max(linch + goffset, ginch) + 0.1
par(mai = nmai)
}
Thank you,
Stephen Weigand

Very slow plot rendering with X11 on CentOS 5.5
I am connecting from a PC to a Linux system running CentOS
release 5.5 (Final) and it is extremely slow to render plots
to the X11 device.
This is not R's fault but I wonder if anyone can offer
guidance so I can help the system administrators address
the problem.
I can connect to the Linux server using a NoMachine NX client
for Windows or using X-Win32. I also have access to R running

'sep' argument in reshape()
I wonder if the 'sep' argument in reshape() is being ignored
unintentionally:
## From example(reshape)
df <- data.frame(id=rep(1:4,rep(2,4)),
visit=I(rep(c("Before","After"),4)),
x=rnorm(4), y=runif(4))

tiff(), jpeg(), and png() in R 2.7.0: problems if 'units = "in"' but default height and width
I love the new tiff(), jpeg(), and png() in R 2.7.0 but found
an issue that I didn't see reported.
When specifying 'units = "in"' but forgetting to change the
default height and width (so the figure is unintentionally
going to be 480 inches by 480 inches) I run into problems.
Here's the reproducible example:

p-level in packages mgcv and gam
Hi,
I am fairly new to GAM and started using package mgcv. I like the
fact that optimal smoothing is automatically used (i.e. df are not
determined a priori but calculated by the gam procedure).
But the mgcv manual warns that p-level for the smooth can be
underestimated when df are estimated by the model. Most of the time
my p-levels are so small that even doubling them would not result

testing non-linear component in mgcv:gam
Hi,
I need further help with my GAMs. Most models I test are very
obviously non-linear. Yet, to be on the safe side, I report the
significance of the smooth (default output of mgcv's summary.gam) and
confirm it deviates significantly from linearity.
I do the latter by fitting a second model where the same predictor is
entered without the s(), and then use anova.gam to compare the

Nonnormal Residuals and GAMs
Greetings, My question is more algorithmic than prectical. What I am
trying to determine is, are the GAM algorithms used in the mgcv package
affected by nonnormally-distributed residuals?
As I understand the theory of linear models the Gauss-Markov theorem
guarantees that least-squares regression is optimal over all unbiased
estimators iff the data meet the conditions linearity,

two basic question regarding model selection in GAM
Qusetion #1
*********
Model selection in GAM can be done by using:
1. step.gam {gam} : A directional stepwise search
2. gam {mgcv} : Smoothness estimation using GCV or UBRE/AIC criterion
Suppose my model starts with a additive model (linear part + spline part).
Using gam() {mgcv} i got estimated degrees of freedom(edf) for the smoothing
splines. Now I want to use the functional form of my model

Use generalised additive model to plot curve

I have been reading 'the r book' by Crawley and think that the
generalised additive model is appropriate for this problem. The

question about predict.gam
I'm fitting a Poisson gam model, say
model<-gam(a65tm~as.factor(day.week
)+as.factor(week)+offset(log(pop65))+s(time,k=10,bs="cr",fx=FALSE,by=NA,m=1),sp=c(

Currently I've difficulties in obtaining right predictions by using

syntax).

gam, what is the function(s)
Hello,
I'd like to understand 'what' is predicting the response for library(mgcv)
gam?
For example:
library(mgcv)
fit <- gam(y~s(x),data=as.data.frame(l_yx),family=binomial)
xx <- seq(min(l_yx[,2]),max(l_yx[,2]),len=101)
plot(xx,predict(fit,data.frame(x=xx),type="response"),type="l")
I want to see the generalized function(s) used to predict the response

methods() not listing some S3 plot methods...?
Dear List,
This may be related to this email thread initiated by Ben Bolker last

In answering this Question on StackOverflow
http://stackoverflow.com/q/7195628/429846 I noticed that `methods()` was
not listing some S3 methods for `plot()` provided by the mgcv package.

Dear R-users:
Im trying (using gam package) to develop a stepwise analysis. My gam
object contains five pedictor variables (a,b,c,d,e,f). I define the

Dear all,
I've now spent a couple of days trying to learn R and, in particular, the
gam() function, and I now have a few questions and reflections regarding
the latter. Maybe these things are implemented in some way that I'm not yet
aware of or have perhaps been decided by the R community to not be what's
wanted. Of course, my lack of complete theoretical understanding of what

I'm a fairly new R user having two questions regarding gam:

predictions based on the original data set, by leaving out the 'newdata'
argument ("newd" in the example), I get an error message
