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.

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

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),

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

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

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

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

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. Base graphics offers coplot, utilizing the

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.] library(lattice)

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 -------------------------------------------------- David Kowalske Jr Graduate Research

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

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

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

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 not succeeded

Hi everyone, I have two questions: I would like to get confidence intervals on the coefficients derived from the optim() function. I apply optim() to a given function f > res <- optim(c(0.08,0.04,1.),f,NULL,method="L-BFGS-B",lower=c(0.,0.,0.)) And I would like to get the p-value and confidence intervals associated with > res$par My second question deals with error message. I

Hi, I am having problems using .First() with the Mac OS X gui version of R 2.7.2 (under OS X 10.5.5); .First is ignored on startup. .First() does work in the command-line version of R under Mac OS X but my specific task requires the gui version. I can find no reference to this issue in the Mac OS X FAQ or in other manuals, does anyone have a solution for this? Thanks, Ian -- Ian Jonsen

Can someone give me an idea of the processor power I will need for 1 x TDM240 with 2xquad FXO's and 8 sip phones/ATA's on a quite 100Mbit LAN.

Hi, I have been working with R for the last year and using the UKFSST package to look at satellite tag track data and SST information. Fpr those not familiar, the package uses the positions estimated by the satellite tags themselves and the associated SST data from servers (in this case, from the University of Hawaii and the NOAA Coastwatch website) for the time preiod to estimate a reasonable

Hello, I'm having difficulty passing an object name to a lapply function. Can somebody tell me the trick to make this work? #Works T13702 <- TRACKDATA[["13702.xls"]][["data"]] min(unlist(lapply(list(T13702), function(x) mdy.date(x[1, 2], x[1, 1], x[1, 3])))) 16553 #Works d<-2 assign(paste("T",substr(names(TRACKDATA)[d],1,(nchar(names(TRACKDATA)[d]
