similar to: plot functions, formula interfaces and NAs

I have been tinkering with mosaicplot() and friends as a way of learning R. As part of this, I've written a pair.table() method for mosaic matrices, and would like to extend mosaicplot to work with loglin and logln (MASS) objects. I'm using R 1.4.0 on Win 98. I've been trying to figure out the formula interface, and think there's a bug, but not sure how to find it, yet alone fix

Hi, Can someone set me straight as to how to write formulas in R to indicate: complete independence [A][B][C] joint independence [AB][C] conditional independence [AC][BC] nway interaction [AB][AC][BC] ? For example, if I have 4 factors: hair colour, eye colour, age, sex does > mosaicplot( frequency ~ hair + eye + age + sex) mean that the model fitted is of complete independence of

Quite a few packages have used this construct to launch a device, but it has several flaws. It's not clear in most cases that a package really needs to launch a new device (R will do so if needed), but 2.7.0 provides a function dev.new() to do so. (If you really need this in a GPL-ed package that must run in R < 2.7.0, consider copying dev.new.) You cannot assume any arguments for

Hello Pardon for the elementary question, I did try searching the archives with various terms, but to no avail. I am using R1.9.1 on a windows machine One of the great advantages of R (to me, anyway) is being able to see the code for a function , e.g. by typing sd one sees the code for getting a standard deviation. However, for many functions this only provides info. including UseMethod, eg.

What library(help=foo) produces is not HTML and has no hyperlinks, so why do you want it displayed in a browser? If you do want text displayed in a browser, you can set options("pager") to point to your browser (or a wrapper). It is no different from other library() help modes, like library() with no argument, nor from help(package="foo"). Indeed, the help for help says

BIll, Thanks. I am seeing some problems here, for example when all the fields are missing, or all the fields in a row are missing. I've fixes for those, and will commit to R-devel shortly.

There is an even simpler way: someone wrote n*(n^2-1) as n*(n-1)*(n+1) and caused the problem. Your superfluous semicolons do definitely make your code harder to read.

Hello. I've been using R for a couple of months and enjoying it a lot. This is my first post to R-help. I'm using the vcd package to make mosaic plots with labels on the tiles indicating the number of items in each cell. For example, I've made this plot: > allmorph<-structure(c(10, 26, 17, 100, 70, 97, 253, 430, 185, 177, > 25, 1), .Dim = as.integer(c(6, 2)), .Dimnames

No objections from Martin or elsewhere, so I have now committed this. Thanks, Uwe.

Uwe, You said you used testdata <- data.frame(date = strptime(c("31121991", "31121991"), "%d%m%Y"), nothing = c(NA, NA)) but that's not the same object, and that one does work for me. > dput(testdata) structure(list(date = structure(c(694137600, 694137600), class = c("POSIXt", "POSIXct")), nothing = c(NA, NA)),

I'm pretty sure that I did everything right, but my R is just not drawing the mosaicplot that I want, and there is also no error messege, looks like this right now: > mosaicplot(arthritis) > mosaicplot(~ sex + treatment + improved, data = arthritis, color = TRUE) > -- View this message in context: http://r.789695.n4.nabble.com/problems-with-mosaic-plot-tp3090128p3090128.html Sent

Two proposals for mosaicplot(): - The argument "sub" should not be ignored. Example: mosaicplot( HairEyeColor, sub = 'test of sub' ) - To be able to discern also longer axis labels the argument "las" or par(las=2) should not be ignored. Example: mosaicplot( HairEyeColor, las=2 ) Thanks Wolfram

I've just started learning R, so I'm still on the steep part of the learning curve, but my enthusiasm was heightened by learning that there's a very nice implementation of mosaicplot(). As a learning project, I've already done a basic implementation of a pairs.table() function which does a mosaic scatterplot matrix, and now I'm trying to do conditional mosaic plots (discrete

Full_Name: Greg Kochanski Version: 2.2.1 OS: Debian Linux (testing) Submission from: (NULL) (212.159.16.190) mosaicplot(x, shade=TRUE) is intended to color the blocks blue if they are more common than one might expect and red if they are rarer than one might expect. Unfortunately, if a block is much rarer than expected, it is so narrow that one cannot see the red. Thus, a casual inspection

Thank for your help I obtained profiles and I found mosaicplot as an interesting alternative. I don't like my solution about legend in profiles graphics: I inserted empty extra columns in order to avoid tue superimposed of legend. #Data N <- matrix(0,3,6) N[1,] <- c(7,7,5,0,4,4) N[2,] <- c(0,0,0,5,5,5) N[3,] <- c(4,4,0,0,3,0) rownames(N) <-
