Hello, I read a book about statistics in psychology. The authors use SPSS. They talk about post hoc tests after ANOVA finds significant effects: - Gabriel's procedure (for equal or slightly different sample sizes) - Hochberg's GT2 (for different sample sizes) - Games-Howell procedure (for populations with unequal variances) I could not find them in R. Do they not exist in R

Hello, I use t.test for normal distributed and wilcox.test for non-normal distributed samples. It is easy to write a function for t.test that calculates the effect size, because all parts of the formula are available from the t.test result: r = sqrt(t*t / (t*t + df)) However, for Wilcoxon tests, the formula for effect sizes is: r = Z / sqrt(N) I wonder how I can calculate the Z-score in R for

Hi, I produce a series of diagrams with R in order to include them in my documents (LaTeX). However, there is a white border around the diagrams. For some that do not have anything written at the very bottom, the white border is relatively large. The rather big space between figure and caption at the final document looks not nice. It would be best not to have any white border. I played with

Hello, I have a table (1) of the form q1 q3 q4 q8 q9 A 5 2 0 1 3 B 2 0 2 4 4 I have another table (2): q1 q2 q3 q4 q5 q6 q7 q8 q9 C 10 7 4 2 6 9 3 1 2 I would like to divide the numbers in table (1) by the number of the appropriate column in table (2): q1 q3 q4 q8 q9 A 5/10 2/4 0/2 1/1 3/2 B 2/10 0/4 2/2 4/1 4/2

Hi, I have a data frame named "questions" that I use to get a subset and then a table: failcondonly <- subset(questions, errorreason=="condition") failcondtab <- table(failcondonly$type, failcondonly$qid, exclude=c("ORGA", "skipped")) The failcondtab looks like this: 6 11 12 13 14 15 17 26 30 31 39 41 gave up 0 1 1 1 1 0 0 0 0 8 0

Hi! I'm doing: etni <- subset(etni, NAMECOM!="Maniquisito") where etni is a data.frame, NAMECOM a factor and "Maniquisito" labels a row that I want to delete. The problem is that while the row is deleted, the factor level is still there (I can see "Maniquisito" if I do levels(etni$NAMECOM) ). I know I can get the appropriate levels by:

Dear list, subset has a 'drop' argument that I had often mistaken for the one in [.factor which removes unused levels. Clearly it doesn't work that way, as shown below, d <- data.frame(x = factor(letters[1:15]), y = factor(LETTERS[1:3])) s <- subset(d, y=="A", drop=TRUE) str(s) 'data.frame': 5 obs. of 2 variables: $ x: Factor w/ 15 levels

Hello, certain manipulations of ggplot2 graphs, in particular aligning them, require the function grid:::unit.list().

Hi ALL, I have a harddisk with 3 primary partitions and one extended partitions. Under extented partions , there are 15 partions. Whole hard disk has been partitioned in a standard way, (i.e NOT LVM) It has 2GB ram. swap is also 2GB. Now I want to extend this swap to 4 GB. If I use dd coomand and create a file with 2GB, Will I be able to extend the swap witn swapon commnad? How can I achive

Paul, Subassignment for units has been committed to r-devel. You should now be able to do things like ... x <- unit(1:3, "mm") x[2] <- unit(.5, "npc") (see grid/tests/units.R for more complex examples) Yes, I just tried the latest R devel and it works for me. However: This works for me for the three stackoverflow scenarios. I ran into an additional problem when

I find that after subsetting (you may prefer "conditional selection") a data frame and assigning it to a new object, the str(new object) reflects the original data frame, not the new one: A <- rnorm(20) B <- factor(rep(c("t", "g"), 10)) C <- factor(rep(c("h", "l"), 10)) D <- data.frame(A, B, C) str(D) # reports correctly E <-

Hi, I've written some C code for density evaluation of the non-central t distribution. It works with the R-1.7.1 source code if placed in the src/nmath directory and after appropriate changes are made to Makefiles, to the dt function in src/library/base/R/distn.R etc. I haven't read a lot of R source code so it may need some R-ification, but I've tried to use the dt.c file as a

Dear R-bugs I have been studying the StructTS function (in package 'stats') and functions supplied with it. I think I have found a few minor bugs in the documentation.
