My previous post about prcomp and princomp was done in some haste as I had long ago indicated to Kurt that I would try to have this ready for the June release, and it appeared that I would miss yet another release. I also need to get it out before it becomes hopelessly buried by other work. Brian Ripley kindly pointed out some errors, and also pointed out that I was suggesting replacing some

Hi Paul Is there a concrete working example somewhere that shows how to use these to do an animation on Windows (R Gui &/or RStudio) using base R plot() and friends? I have several old examples somewhere that used to work (R < ~ 3), but now no longer work as before.

It used to be the case that when I submitted a package and it gave notes or warnings in the CRAN checks, I was required to bump the package version before re-submission. I hope this is no longer the case.? I recently submitted a package that gave one fairly trivial NOTE, fixed that, and would like to re-submit. -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor,

Have you looked into your .Rprofile file? Loading packages is not something R normally does without your telling it to do so, but many people forget that they have done so.

[env: Windows, R 3.6.6] When I start R from the R Gui icon or from RStudio, I get a large number of packages loaded via a namespace. Not entirely clear where these come from. As a result, I often run into problems updating packages because something is already loaded. How can start a new gui session with minimal packages loaded? > sessionInfo() R version 3.6.3 (2020-02-29) Platform:

I'm trying to make a screeplot including the Cumulative Proportion of the Variance, something that can easily be done in S-Plus with 'screeplot(pc.object,cumulative=T)'. How can I access the Proportion of Variance in an princomp object and how could I get the Cumulative Proportion of the Variance on the screeplot? Many thanks in advance, Jan:-) --

Can you be more specific about what conditions cause R to automatically load a package when a .RData file is loaded? My experience has actually been the opposite.

As Jeff says, it might be that you have a ~/.Rprofile file with instructions to load packages when R starts. It could also be that you have a .RData file, which is saved if you answer yes to: > Save workspace image? [y/n/c]: y when you quit R. If this file exists, then R loads it and all the objects you had when you saved it. If there are objects associated with packages, then that will

Following some discussion on R-help, I'd like to propose that an as.matrix method be added to those available for ftable objects. The reason for this is that there are a variety of situations where one needs to flatten a 3+ way table, but then use that for analysis as a matrix, not just for pretty-printing. There is an as.table method to turn the result back to a table, but an as.matrix

Full_Name: Gavin Simpson Version: 2.5.0 OS: Linux (FC5) Submission from: (NULL) (128.40.33.76) Screeplots are a common plot-type used to interpret the results of various ordination methods and other techniques. A number of packages include ordination techniques not included in a standard R installation. screeplot() works for princomp and prcomp objects, but not for these other techniques as it

Hi I'm trying to make a 3d plot showing a point cloud, the corresponding data ellipse and the principal axes of the ellipse as vectors. library(rgl) data(trees) cov <- cov(trees) mu <- mean(trees) plot3d(trees, type="s", size=0.5, col="blue", cex=2) In this step, an extra box is added. I've tried using box=FALSE, but it has no effect. # how to avoid the

Hi Sergio Doing those tests 30 times is going to give you a huge Type I error rate, even if there was a function that did that. There is a reason why TukeyHSD doesn't make it easy. In general, if there are useful comparisons among the species, you are better off setting up and testing contrasts than doing all-pairwise Tukey tests. Also, the PCA scores are ordered in terms of variance

Hi, Suppose I've got a data set that I found the eigenvalues and eigenvectors. Then I want to draw a screeplot for the eigenvalues. However it returns: Error in matrix(w.m, nc = NC) : negative extents to matrix Then I tried a plot() function on the eigenvalues of the data set, and I can successfully draw it! And the output looks like what the screeplot would show to me. Is there any

Under Windows (and maybe others) you can use file.choose() as a substitute for an explicit file= argument in most places. Is there an analog for what I'll call dir.choose(), so that I can say setwd(dir.choose()) thx, -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept.

A simple question, but I can't find something to do what I want: Given: a vector of numbers, like lambda <- c(0, 0.005, 0.01, 0.02, 0.04, 0.08) Desired: format them in minimal space for use as plot labels, ie, without leading or tailing 0s. For this example: lambdaf <- c("0", .005", ".01", ".02", ".04", ".08") -- Michael
