Hi, I am trying to plot different variables from a data.frame using lattice's xyplot using code like that below. How do I specify a symbol and color for the variable 'prob' and different one's for 'll.prob'? Thanks, Matt xyplot( prob + ll.prob ~ time.eff |stat.id + time.out ,data = OUT, allow.multiple = TRUE, layout = c(6,3), as.table = TRUE ,

Hi, I am having problems creating a pdf file of a lattice graph. Things work fine for a single image, but I am having trouble using the commands in a loop. To illustrate by example This works with both ps and pdf files. dat = list(x= 1:10, y = 1:10) trellis.device(postscript, file = "/d1/pocernic/test.ps") xyplot(y~x, data = dat) dev.off() This does not. It produces a very

Hi, I realize the answer is very likely in the section Generic functions and methods (or Adding new generics), but I'm not clear what to do with the following. Running R CMD check, I get the following warnings for my generic functions. Does this mean I need the argument * checking generic/method consistency ... WARNING leps: function(x, ...) leps.default: function(x, pred, titl,

Hello, I have been having difficulties opening netcdf files using the netcdf library. I am able to successfully open the file and I can determine the names and size. However, when I try to read it I receive an error. Reading the documentation, I am wondering if this might be due to a difference between netcdf version 2 and more recent netcdf format? I've tried using different values for the

Hi, I was lately debugging parts of my 'colAUC' function in caTools package, and in a process looked into other packages for calculating Areas Under ROC Curves (AUC). To my surprise I found at least 6 other functions: * wilcox.test * AUC from ROC package, * performance from ROCR package, * auROC from limma package, * ROC from Epi package, * roc.area from verification

Hi, How do I convert a numeric value indicating the time since 1970, back into a POSIXct class object? I have tried format.POSIXct and as.POSIXct without success. For example > ccc [1] "1945-01-01 15:00:00 MDT" > ddd<- as.numeric(ccc); > ddd [1] -788842800 > format.POSIXct(ddd) Error in format.POSIXct(ddd) : wrong class > as.POSIXct(ddd) Error in

The verification package has recently been posted to CRAN. This package was initially developed by people in the Verification Group at the National Center for Atmospheric Research to verfiy and study weather models and forecasts. It has been written in general terms to be applicable to other fields of study. Functions include receiver operating characteristic curves attribute diagrams

Hello, I have a question about using the layout command within a function. I've written function that uses layout to create a figure from 2 plots. This works fine to create a figure. When I use par(mfrow = c(2,2)) to create multiple plots, it seems that the layout command resets the mfrow parmeter. Is there a way for me to avoid this problem? For example practice<- function() {

Dear R-list, I would like to use the lattice library to show several groups on the same graph. Here's my example : ## the data f1 <- factor(c("mod1","mod2","mod3"),levels=c("mod1","mod2","mod3")) f1 <- rep(f1,3) f2 <-

R users, I am creating a series of scatterplots with Lattice's xyplot(). Some of the plotting symbols are squares with thick borders. The corners of the squares are rounded by default; I would like them to be square. In base graphics this is easily done with par(ljoin = "mitre"), and in grid graphics with gpar(linejoin = "mitre"). Is there an analogous parameter in

Dear R Users, I recently posted an email on this list about the use of data.frame and overlaying multiple plots. Deepayan kindly indicated to me the panel.superposition command which worked perfectly in the context of the example I gave. I'd like to go a little bit further on this topic using a more complex dataset structure (actually the one I want to work on). >mydata Plot

Hello, I am using e1071 to run support vector machine. I would like to plot the data with lattice and specifically show the hyperplanes created by the system. I can store the hyperplane as a contour in an object, and I can plot one object at a time. Since there will be thousands of elements to plot, I can't manually add them one by one to the plot, so I tried to loop into them, but only the

Full_Name: James Szinger Version: 2.4.1 OS: linux and MacOS X Submission from: (NULL) (128.165.24.206) I'm trying to plot some data from the past 12 months and the lattice package is not labeling the time axis correctly. It shows only two labels instead of the expected 12. The base graphics get it right. I think the problem is the commented-out line in formattedTicksAndLabels.Date in

I'm sure this question is answered in the help file, but likely I'm not reading it corrected. Running windows version 1.00.0, loading a table (35K rows by 10 columns) from Excel using the read.table command I receive the following message. Error: cons memory (350000 cells) exhausted See "help(Memory)" on how to increase the number of cons cells. >From reading the

Hi - I would like to create a scatterplot with the symbols coded by a factor in each record. Is their a better way than what I have used below? I attempted to use the plot.factor, but cannot force it to make a scatterplot instead of boxplots. I have considerd making a function with a 'for' statement for each level of the factor. Is there a better way for when I am dealing with more

Dear list members, Within a loop, I need to create an xyplot with only a legend, not even with the default external box drawn by lattice. I already managed to remove the axis labels and tick marks, but I couldn't find in the documentation of xyplot how to remove the external box. I would really appreciate any help with this ------------- START ----------- library(lattice) x<-1:100

Dear R-help subscribers, I use xyplot to plot longitudinal data as follows: score<-runif(100,-4,5) group<-sample(1:4,100,rep=T) subject<-rep(1:25,4) age<-rep(runif(4,1,40),25) df<-data.frame(score,group,age,subject) xyplot(score~age|group, group=subject, panel=function(...){ panel.loess(...,lwd=4) panel.superpose(...)} ,data=df) this produced a plot with four panels one for each

Dear R-users, I have written the following code to generate some trellis plots. It works perfectly fine except that it is quite slow when it is apply to my typical datasets (over several thousands of lines). I believe the problem comes from the loops I am using to subset my data.frame. I read in the archives that the tapply function is often more efficient than a loop in R. Unfortunately ,
