Postscript device bug when more than one page is needed?
It would appear to me that there is a bug in the postscript device when multiple pages are required. Line widths can be only 1 after the first page. I have not seen reference to this as a problem before. test.device <- function() { # looks like the problem is in the postscript device postscript(file = paste("Test.ps"), horizontal = F) on.exit(dev.off())

Matrix manipulation
I have a square matrix wherein a '*' indicates an HSD between the levels indicated by row name and column name. The '.' is simply marking the diagonal. A blank indicates the same group A B C D E F G H I J K L M N A . B . C * * . D * * . E * * * . F * * * .

kinship package example data
I've been looking at the kinship package which looks as though it might be appropriate for my purposes. What I can't find is any reference to the data that is used in the example code. A dataframe called d10 with column names, upn, dadid, momid, sex and affect is required. One can get an idea of what sort of values should be in most columns from the description in the pedigree function,

one question about title
Dear, Thanks for your help. My question is the title can not completely show in the drawing area when the title is too long. So, I need to change the value of cex.main each time. Could you help me to control the title display area?

How do I get 10^4 to become 10000?
Of course, that's as trivial as it gets on the command line, but I can't work out how to get a column of numbers that are entered as "10^5" from its 'character' format into a numeric one? I feel a bit embarrassed asking such a simple question. Too much Easter.... Thanks -- Patrick Connolly HortResearch Mt Albert Auckland New Zealand Ph: +64-9 815 4200 x 7188

More on list to data frame (was: Re: List to Data Frame
Hi, Now suppose I have just one list called FOO, which has 25 objects, e.g.: [[1]] 1 2 3 4 5 [[2]] 6 7 8 9 10 . . . And I want to do something like: FRED <- data.frame(cbind(unlist(FOO[[1]]), unlist(FOO[[2]]), # ... for all 25 subsets )) Is it possible to do this, without doing unlist(FOO[[i]]) 25

Canonical Variance Analysis by any other name?
I've been asked about "Canonical Variance Analysis" (CVA). I don't see any reference to it searching the R site. Does it go by other names? Genstat describes it thus: Canonical variates analysis operates on a within-group sums of squares and products matrix, calculated from a set of variates and factor that specifies the grouping of units. It finds linear combinations of the

make check failure with R-1.7.0
I'm baffled. When I run make check after installing from source, I get a Error 2. From my understanding of how these things work, it would appear to be coming from this (as at the end of base-Ex.Rout.fail: > has.VR <- require(MASS, quietly = TRUE) Attaching package 'MASS': The following object(s) are masked from package:base : confint confint.lm nclass.FD nclass.scott

more mulitpage postscript problems
Hi, I posted a while ago about 'overlap' problems using png/jpeg. If what Patrick Connolly suggests is truly happening, I think the following may be related. My new problem is with the following code (the overlap is still there if I use png() instead of postscript(), compounded by the difficulty described below): tmp <- matrix(runif(16000), nrow=16)

Level sets of factors are different (panel.superpose)

How do we omit the coastline using map?
I've been able to do most things I'd like to using the map package, but I can't figure out how to fill a region without drawing a black outline. I can draw the outline in a specified colour, but as soon as I set fill to TRUE, I get a black outline in addition. My map has a lot of activity on the coastline so I don't want a black line obscuring what I do there. A pale colour to

Binomial glms with very small numbers
V&R describes binomial GLMs with mortality out of 20 budworms. Is it appropriate to use the same approach with mortality out of numbers as low as 3? I feel reticent to do so with data that is not very continuous. There are one continuous and one categorical independent variables. Would it be more appropriate to treat the response as an ordered factor with four levels? If so, what family

Does the perl language have an equivalent to browser?
I'm asking on this list because the question will be more easily understood than on a Perl list. Lots of talented people using R also know how to use Perl, so it's easier to ask them. Running a Perl script with the -d switch can do some pretty neat things, but as far as I can tell, every line has to be done individually. Is there a way to specify where to stop in the way browser() does

Removing trailing spaces
Some years ago when I used S-PLUS, I seem to remember, there was a discussion about a simple method of removing trailing spaces from vector elements. I'd be fairly sure the same would work in R, but I can't find any mention of anything like it in the R archives or with help.search(). There are ways I could do it with substring(), but I seem to remember there was something more elegant.

grid graphics and par settings
I see that adj is not a graphical parameter that can be used in a key list to use with lattice functions. Is that because it's not yet implemented in gpar? If so, it could also explain why it's not available in grid.text. Is there a work around? Centering looks silly on my plot. best -- Patrick Connolly HortResearch Mt Albert Auckland New Zealand Ph: +64-9 815 4200 x 7188

How to get time differences in consistent units?
I'm still having trouble getting to grips with time classes. I wish to calculate the difference in days between events.
