Sir, Would like to know what sort of input matrix are taken by the kmeans function defined in mva library of R application. As per the documentation for the Kmeans it takes the following 2 data sets: 1) data 2) centers The commands to be executed in R are as follows: library(mva) data <- read.table('file1',header=TRUE,sep="\t") centers <-

Since I sent my original question last week, this is one of two suggestions that worked. Using Adobe Acrobat, as suggested by Professor Ripley, was very satisfactory, but required that I use multiple platforms to make the conversion to PDF (from Linux to Windows). The solution by Peter Adorjan (included below), also worked very well, and can be carried out on any platform using tools available

Hi I have a matrix (4 x 950) and I want to remove 3 rows, where the values from the first column are 713, 714 and 715. I can select the rows, one by one, with mat[mat$first==713,] mat[mat$first==714,] ... but I'm unable to (i) select the 3 rows at once, (ii) select the matrix excluding those rows. How can I do it ? Thanks EJ

Rers, I have been using the function 'by' in such a manner: by(LogMetric, list(Loci.Number=Loci.Number, Code.Flag=Code.Flag), plot) with par(mfrow=c(5,3)) to produce a single R Graphics: Device with 14 different plots on it as described above in my 'by' statement. Thank you for helping me thus far. A similar command using 'tapply' can be written as well. My

g'day R friends, can anyone please help me with a frustrating merge? The number of rows of a resulting merge is the smaller of the 2 dataframes used as input. What am I doing wrong?

Hallo, I've produced via R-0.62 several Life-tables 50*6 (mfrow=c(2,3)) as postscriptgraphs. The phd student, who asked for this, use word for windows--therefore i converted the whole stuff with pstoimg to gifs. Unlikly the result is not sufficient (I was told)... Is there a tool to convert ps to wmf/emf ? I looked for it but haven't found anything... Thanks for an answer Peter

Hi, I am starting tu use R on a linux environment (Red Hat 6.0), and when I tried to use library MASS, writting library(MASS) I got the following message: > library(MASS) Error: dynamic library `MASS' not found > Is there something I am doing wrong?

I installed ESS but I can't figure out what needs to be set for it to recognise R. I gather it's something to do with .emacs file, but none of the help files seem to mention it. Like everything, it's probably easy once you know, but so far I don't know where to look. Thanks for any help. best Patrick

Dear R-Help, I know that R already includes conditioning plots (two variables/factors) but is there any intention to incorporate an equivalent of Trellis (Splus) multi-conditional plots in R ?

Hi, I would like to know if it is possible to make global variables in R. My problem is that I use the same data frame in many different functions that I have written, but it implies a very big waste of time because it slow down the program. So I would use my data frame without need to copy it each time in another function to have a faster program execution. How can I do ?? Thanks for Help

One Question: if I make a lattice-plot (beware: under development!) with a special layout e.g. c(2,2,4): p1 <- xyplot(y~x|id,data=data,layout=c(2,2,3)) is there a way to print.trellis e.g. the second page of the trellis object "p1"? print.trellis(p1,page=2) #!wrong! I want this to automatically dev.print the pages (no, I don't want multiple postscript pages). If this

One of our students did something like: x[a < b < c] instead of x[a < b & b < c] But why is 3 < 2 < 1 # [1] TRUE ??? Is there any reason? Or wouldn't it be better to get a warning / error?

I have the following question, which is elementary but I am unable to answer. In a for(i=10) loop, I am trying to represent the 10 1-dimensional vectors l1, l2,... l10 by some expression that will run through these values. ie. soppose I want to add l1 + ... + l10 I could go x <- 0 for(i in 1:10){ x <- x+ l(i)} This should return x to be the sum of the 10 li's for i from 1 to 10

I have to admit that I'm a bit ignorant about regular expressions...I have a problem with "gsub": under unix I can : > cat tmp.txt F.123 F.123 F123 F123 sed 's/F\./d/g' tmp.txt d123 d123 F123 F123 that is: replacing "F.", however under R: gsub("F\.","d",c("F123","F.123"),extended=F) [1] "d23"

Hi all, I'm having two small problems and was wondering if you could help me out. Problem 1: When I use pch to place a symbol onto a plot it seems to place the point a little off the exact location. I have read the help file for this which says to use "." as the plotting character, which will then produce centered points but I am unclear as to how to do this. Problem 2: How do I
