crashing R through lattice
I have been crashing R while using lattice. My system consists of a Mac
Intel, R 2.5.1, lattice 0.15-5, and I plot through the default quartz.
R crashes after plotting several lattice functions. Has anyone else
encountered this problem and does anyone know the cause, or a solution?
Is this a lattice:mac, lattice:quartz, Lattice:me issue?
example...
This crashes my system after plotting.

tcl/tk help
I am running R 2.5 on a Mac platform and have a difficulty loading the
Tcl/Tk package.
Specifically:
R>library(tcltk)
Loading Tcl/Tk interface ... Error in fun(...) : couldn't connect to
display ":0"
Error : .onLoad failed in 'loadNamespace' for 'tcltk'
Error: package/namespace load failed for 'tcltk'
Is there an explanation to this problem? Thank you

fitting periodic 'sine wave' model
I have been attempting to estimate the periodic contribution of an
effect to some data but have not been able to fit a sine wave within R.
It would be nice to start by being able to fit a sine wave with an
amplitude and frequency.
x<-seq(0,20,by=0.5)
y<-2*sin(2*pi*.5*x) #amplitude =2, frequency=0.5
# This failed to converge
r<-nls(y ~ A*sin(2*pi*F*x), start=list(A = 1, F = 1),

apply function across two variables by mult factors
Greetings,
I am attempting to run a function, which produces a vector and
requires two input variables, across two nested factor levels. I can
do this using by(X, list(factor1, factor2), function), however I
haven't found a simple way to extract the list output into an
organized vector form. I can do this using nested loops but it isn't
exactly an optimal approach.
Thank you

Automate a data load and merge
Hi R list,
I would like to automate, or speed up the process from which I take
several separate datasets, stored in .csv formate, import and merge
them by a common variable. So far I have greatly sped up the loading
process but cannot think of a way to automate the merger of all
datasets into a common data.frame.
My apologies if this has been covered, any R search suggestions are

polygons on scatterplot3d
Does anyone have any experience plotting complex polygons on a
scatterplot3d display? I would like to present some spatially binned
data in a 3-d type plot with background polygons (i.e.. a filled
coastline map). I can get the coastline onto the plot window as a
line type but cannot figure out how to fill the shape. I'm certain it
may be possible but might require a bit of digging

Conditionals for Errors or error flags
Greetings,
I have been working on a script that conducts repeated statistics and
plots to my data. In this case it is sub-setting the dataframe by
month.
The intent is to develop a custom analysis and plotting that I can run
on a large number of data sets.
Unfortunately, a small portion of my subsets (~1%) cause an error with
one of the wrapped subroutines that results in the whole

html search not working
Sorry the first email had no subject.
I've searched around and havent had much luck trying to explain why my
HTML search no longer works. If I use
?cor.test
it is unable to display the webpage. Is this a java problem? I am
running windows xp, and use Internet explorer for my default browser.
Thanks

lattice shingle with time and date format
Hi R-Users,
I have a time series of bivariate observations (x,y,t). I've
developed a few panel routines to explore certain aspects of the data,
and now would like to break the time series up into smaller chunks to
explore the temporal trends. I would like to know if anyone has any
experience breaking up time series with lattice.

maps and lattice
Is it possible to place maps onto lattice plots?
With basic plotting you can add a map to a plot
library(lattice)
long<-c(-69.2, -69.5, -70.1, -70.3)
lat<-c(41, 41.5, 43.2, 42.8)
plot(long, lat)
map('state', c("massachusetts"),add=TRUE)
but is it possible with lattice?
library(lattice)
factor<-c(1,1,2,2)
xyplot(lat~long|fact)
...now what?
I have looked at panel and

custom panel help in lattice
Hi,
I am having an issue with a custom panel for lattice. The problem
comes when I try passing a groups argument.
Here is the custom panel, a wrapper for smooth spline. I copied
panel.loess and replaced the loess arguments with smooth.spline().
[Note: I would like to use the cross-validation fitting properties of
smooth.spline.]

"old" rpm version package handling broken!? (SuSE8)
Hi!
Using (among others) the pretty old SuSE8.1, I cant get puppet to
install packages.
The rpm programms bahaviour was changed somewhen between versions 3 and
4 (sry, don´t know exactly when) and the old version does not support
the "--nosignature" and "--nodigest" params and "--oldpackage" is purely
an update parameter so when trying to install a package I

Plotting a kriging on a map
Hi list,
Well, this time I’ve a doubt with mapping generation.
I was already able to read and plot shapefiles, plot point on this map. All
this without any problems, but now I want to do something that I think, only
Golden Software Surfer is capable of.
I would like to plot a kriging result on the existing map (map script
below). Well I looked for on the net, but I was not able to be sure of

S/R/RWeb/ODBC
I'm looking for an optimal approach to access Oracle databases via RWeb
applications. I'm new to R but familiar with programming functions and web
pages for the S+ Statserver. I'm now going through the motions of migrating
S+/Statserver applications to R/RWeb as a feasability exercise. I can access
databases using ODBC directly in R or S, and using Statserver, but I have
