Can you show us the context? If I had to guess I would say it was a routine to print

I have the following problem. I have some multidimensional data points "x" and a curve "fit" fitted to these points. How can I combine R> pairs(x) and R> pairs(fit,panel=lines) in one plot, so that I can see how good the curve fits the data? A command like R> pairs(x, panel=function(x,y) {points(x,y); lines(lowess(x,y))}) does not work, since I fit the curve in all

On Saturday I finally upgraded a machine from CentOS 4.3 (I think) to 4.5 via yum. Seemed to went fine. However, during the following night /home got mounted read-only because of an EXT3-fs error. The next night happened the same. Also, today, I saw the first-ever kernel crash on this machine. The machine is about three years old or so, went into production two years ago with CentOS 4.1 or so and

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 <-

In S it is possible to "split" a matrix into its rows, using split(matrix, 1:number_of_rows). This is not possible in R. Example: R: R> split(matrix(rnorm(1:20),4, 5), 1:4) Error in split(x, as.factor(f)) : argument lengths differ S: > split(matrix(rnorm(1:20),4, 5), 1:4) $"1": [1] -0.1804794 0.5269439 0.6248224 -0.3243427 -1.2987407 $"2": [1] 0.9384254

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

On Fri, 14 Nov 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

Hi, I am having an issue when creating a postscript file from RGL window. It seems to cut off some of the axis labels. Here is the code I am using. I created a 3D plot using RGL_0.71 with R 2.5 on Windows XP. z1<-c(5,4,1,4.5,2,3,2,1,1) z2<-c(6,8,7,7.5,5,3.5,4,1,1) z3<-c(3,2,4,7,3,4.5,6,2,3) x1<-seq(1,9) x2<-seq(1,9) x3<-seq(10,18) y1<-seq(8,0) y2<--1*y1

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,

The following statements yield a seg.fault: R --vanilla --nsize 500K x <- rep(letters,10000) f <- function(x) {z<-paste("\"",x,"\"",sep=""); z} y <- f(x) Segmentation fault If a turn gcinfo on, I get Garbage collection [nr. 1]... 387529 cons cells free (75%) 3807 Kbytes of heap free (62%) Garbage collection [nr. 2]... 273868 cons cells free

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]
