New Eyes Needed to See Syntax Error
One of many scripts to produce 4 lattice plots on one page keeps throwing an error. I've tried manipulating the file to eliminate the error, but have not been able to do so. The error is: > source('bicarb.R') Error in source("bicarb.R") : bicarb.R:15:1: unexpected symbol 14: 15: hco33 ^ The 'h' is in column 0 so the caret would be column -1, but it's

How to use panel.qqmathline?
Dear R users: How can I use panel.qqmathline, in package lattice, to add straight lines onto the plots generated by qqmath? I read help pages of qqmath, panel.qqmathline, xyplot, ..., but just can't one example that shows how to make it work. For example, > data(sleep) > qqnorm(~ extra | group, data=sleep, aspect=1) how can I use panel.qqmathline? Thanks very much for your help,

error in packet 1
Hello, I'm Giovanni from ROMA.. I can't find a solution for the error: "error using packet 1 the y field is not specified and it has not a default value" (this is my traslation from italian language) The code is: pc<- qqmath(~valori, distribution=function(p) qweibull(p,beta,alpha), prepanel = prepanel.qqmathline, panel = function(x, y) {

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.

qqmath - Lattice error
Hi, Don't have a clue what teh following error message generated by this function call: qqmath( ~val|ind,data = xx ,distribution = function(p){ qt(p,df=20)} ,ylab="Sample Quatinles" ,xlab="Theoretical Quantiles" ,panel=function(x,y) { panel.qqmathline(y , distribution=function(p) qt(p,df=20)

Superpose two QQ-plots (gamma distribution) with, lattice function qqmath()

Problem with memory footprint of qq plot generated with lattice
Dear R helpers, I generate a qq plot using the following function call. qqmath(~val|ind,data=xx ,distribution=function(p) qt(p,df=19) ,ylab="Sample Quatinles" ,xlab="Theoretical Quantiles" ,aspect=1 ,prepanel = prepanel.qqmathline ,panel=function(x,y) { panel.qqmathline(y, distribution=function(p) qt(p,df=19),col=2)

switching y-axis to x-axis for qqmath
This is the qqmath example from the lattice package. I added the scales to the example. I would like to switch the axis and not sure how? Meaning I would like the "height" on the x-axis and the probability on the y-axis. Will you show me the correct syntax for this switch thanks. qqmath(~ height | voice.part, aspect = "xy", data = singer, prepanel =

How to generate 'minor' ticks in lattice (qqmath)
Dear group, I tried to generate labels for every second tick in lattice (qqmath). Version: 0.14-16 Date: 2006/12/01 R version 2.4.1 (2006-12-18) An example: library(lattice) numy=100 y=runif(numy,min=0,max=1) sig=0.05 numsig=length(which(y<sig)) tck.no=11 # number of ticks tcks=1:tck.no labl=as.character(0.1*tcks-0.1) # label for all ticks labl[seq(2,tck.no-1,2)]="" # delete

Changing point color/character in qqmath
Having solved this problem, I am posting this so that the next time I search for how to do this I will find an answer... Using qqmath(..., groups=num) creates a separate qq distribution for each group (within a panel). Using the 'col' or 'pch' argument does not (usually) work because panel.qqmath sorts the data (but not 'col' or 'pch') before plotting. Sorting

Lattice: Add abline to Single Value qqmath() Plot
The data are not normally distributed when untransformed and I'm trying various transformations to see if any would be appropriate to use. The lattice book (fig. 3.10) shows a 2-sample Q-Q plot with an abline but the code for the figure does not include the line. I'd appreciate a pointer to a reference on how to add an abline to a one-sample qqmath() plot in lattice. Rich

How to add the variable name to a qqplot or densityplot in the diagonal of an splom?
splom() doesn't complain here, but writes no names in the diagonal boxes. What am I missing? I believe that I need to add something like grid.text(x, ...) to the diagonal panel, but I don't know how to get it cycle through the column labels. And should varname.col = 'blue', varname.cex = 1 be inside the diag.panel() function? splom(szw[, n], pscales = 0, diag.panel

text in qqmath
Hello, I can't seem to make qqmath plot text. v <- rnorm(8) qqmath(~v) # this is ok, but qqmath(~v, panel=function(x, y) { points(x, y) text(0, 0, 'print me', cex=2)}) isn't ok. The axis frame is printed properly (ie, as in qqmath(~v)), but neither 'print me' nor the points show up on the graph. I can, however, see the upper half of the word 'me' in the

The plot of qqmath
Hello, I would like to inlude the Q-Q plot by "qqmath" into a panel with other plots, say, using par(mfrow=c(1,2)). How can this be done given that "qqmath" refreshes the plotting window and there seems to be no series coming out of it? Thanks Serguei [[alternative HTML version deleted]]

Lattice::qqmath -- groups option question
Does the 'groups' option on qqmath just color the points differently in the main distribution or does it actually overlay separate quantile plots for each subset? I would like to be able to do the latter. --Rich Richard Kittler AMD TDG 408-749-4099

subsetting key on qqmath
Dear R list, The code below puts qq-plots for two of three groups on the one plot. However the legend includes all three groups, ie the auto.key ignores the subset instruction. Is there an easy way to get around this, so that only those groups plotted are included in the legend? y1<-rnorm(100); y2<-rnorm(100)+1; y3<-rnorm(100)+2; y<-c(y1,y2,y3)

I also have several packages in my RW0633 in Windoze and I would like to keep them in one place when I update the R system. Brian say to modify Rprofile to ..lib.loc <- c("c:/MyR/library",.Library) now Rprofile has a line like .lib.loc <- unique(c(unlist(strsplit(getenv("RLIBS"),":")),.Library) Sorry to be dense but where should I put the
