Scatterplot - symbols coded by factor
...e 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 levels of factors? Thanks, Matt Pocernich Y <- c(40,38,30,47,25,32,13,35,27,24,20,13) X<-c(110,75,93,97,60,75,38,140,62,90,45,59) manuf <- factor(rep(LETTERS[1:3],c(4,4,4))) data3 <- data.frame(X,Y,manuf) attach(data3) plot(X, Y, type="n") points(X[manuf=="A"], Y[manuf=="A"], pch = "A")...

lattice.device in loop
...thing like this to produce a large, appended file made from different large datasets. This doesn't work either. trellis.device(postscript, file = "/d1/pocernic/test.ps", onefile = TRUE) for(i in 1:5){ xyplot(y~x, data = dat) } dev.off() Any thoughts would be welcomed.

lattice variable by page
...Using lattice's xyplot, is it possible to specify a variable to group plots by page. For example, if I have xyplot(y~x|A*B*C) could I get a page created for each unique value in variable C ? I am hoping to avoid having pages with the same strip above each plot on a page. Thanks, M Matt Pocernich NCAR - Research Applications Program 303-497-8312

Survey of ROC AUC / wilcoxon test functions
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

Posix Problem, difftime
I am having a series of problems using date time data that has been converted into a POSIXt and POSIXlt classes. I have hourly time series data from 1900 that has been converted from text data. I assume most of my problems come from a mis-underdanding of the POSIX class. My matrix named (aa) for this year is approx 8700 by 4. When I try to calculate the length of posit column ( which is the

Format of the tick label in a histogram
I am producing a series of histograms and would like to control the format of the tick labels. I tried using the exp=1 option, but apparently this can't be set in a higher level plot function. I've unsuccessfully tried to modify the hist command. Any suggestions? Thanks Matt Pocernich -------------- next part -------------- An HTML attachment was scrubbed...
