What am I doing wrong? (please cc me when replying) yy <- 1:10 xx <- yy*2 xYplot(yy~xx,ylab="") #this plots as it should text(.4,5,expression(paste(log, frac(p(b),p(a)) ))) Error in text.default(0.4, 13, expression(paste(log, frac(p(b), p (a))))) : plot.new has not been called yet This is the case even when I write: xxyy <- xYplot(yy~xx,ylab="") xxyy <-

Dear r-helpers, I have six panels: op(par(mfrow = c(2, 3), xaxt = 'n', yaxt = 'n', pty = 's'). Each of them has a variable main = 'i', and xlab = '', ylab = '' I would like to achieve two things: (1) a common x-axis label under panel 5, and one label to the left of panels 1 and 4 (2) minimal space between the panels. I have looked for

Dear R-helpers, (1) How do I add a 'top' label symmetric with the 'bottom' label' in: axis.td <- function(side, ...) { ylim <- current.panel.limits()$ylim switch(side, bottom = { panel.axis(side = side, outside = TRUE, rot = 0, at = 1:3, labels = c(2.0, 3.5, 5.0)) },

I would like to suppress the text 'Scatter Plot Matrix' that appears under the plot.

Dear r-helpers, After updating to R version 2.2.1, 2005-12-20, powerpc-apple- darwin7.9.0 (from binary), JGR wouldn't launch. I then deleted everything I could find related to JGR, and reinstalled it from the latest binary. Both R and JGR are installed in /Applications/ \~LocalApps/mathStat/. Advice on how to identify the source of the problem? My machine: Machine Name:

Dear R-helpers, I would like the bands in an xYplot() to be gray without dark edges. I've tried playing around with col.bands, but that seems not to affect the edges, although changin col.fill does change the fill as I would expect. I would appreciate pointers. _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box

How does one define PDFs as yet undefined in R, such as the ex- gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF would then be the convolution of an exponential PDF, dexp(), and a normal, dnorm(). Kindly cc me in your reply to r-help.

Dear R-helpers, I wasn't able to find out how to override the alphabetical ordering of the rows and columns in a vcd::mosaic plot. I would like to have them each ordered by numerical values in a different column of the data frame that contains the contingency data. I would be most grateful for a pointer toward the solution.

Dear R-helpers, I was curious why the output of summary (and many other functions in R) does not add a separator between the name of a factor and the label of a level (e.g., in the example below, 'group Trt'). If the user had lower case labels (e.g., 'trt'), the output would be particularly hard to read. ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14) trt
