Sirs, may be that a fault exists in the file "postscript" under "r documentation" which contains "Notes on R:A Programming..." at http://www.ci.tuwien.ac.at/R/contents.htm| I did not succeed in reading and printing it. Can You help me? Many thanks in advance. F.Petronio petronio at univ.trieste.it

Dear R-Users and Developpers, Currently R does not include functions to compute the skewness and kurtosis. I programmed it myself in the following way, but probably *real* programmers/statisticians can do that better: mykurtosis <- function(x) { m4 <- mean((x-mean(x))^4) kurt <- m4/(sd(x)^4)-3 kurt } myskewness <- function(x) { m3 <- mean((x-mean(x))^3) skew <-

Hello, I want to try the Design and Hmisc library from FE Harrell but, i have trouble with the copyright for the library Hmisc : in the home of the author : http://fharrell.biostat.virginia.edu/s/unix/ in the file Hmisc.README ###COPYRIGHT NOTICE ###You may not port code in the Hmisc library to R.

...v 1997, Jim Lindsey <jlindsey at luc.ac.be> sent an email to r-devel describing his first shot at porting Design and Hmisc to R. A few days later, his port snapshot of Design was uploaded to CRAN's src/contrib/devel area, and has since been available from there. A few weeks ago, Andreas Weingessel <A.Weingessel at ci.tuwien.ac.at> had a look into porting Hmisc to R (we needed some code for imputation). When he checked with the author, he was not given permission to ``port'' the code. (I guess everyone interested has meanwhile had a look at the most recent version of the Hmisc...

If you plot a vector of numbers which are all very similar (i.e. within the range of some eps), the y-axis is not drawn correctly. Either it is completely missing and there is an additional horizontal line (1st example below) or it is longer than the plotting region (2nd example). x <- c(0.12345678912345678,0.12345678912345679,0.12345678912345676) plot(x) y <- c(0.9999563255363383973418,

If x is a data.frame containing a column of mode character, this column is changed to a factor after applying fix(x). Example: R> x_data.frame(a=1:3,b=letters[1:3],c=c("hansi","pepi","karli")) R> x$c_as.character(x$c) R> is.character(x$c) [1] TRUE R> is.factor(x$c) [1] FALSE R> fix(x) ## I change "karli" to "sepp" R> x$c [1]
