read.table
Sorry to all bothering you with a trivial question: I am using R (rw0630 for Win32) and am simply unable to read-in the *.txt data. I've tried to copy the file (prum.txt) to different directories of rw0630 but get uniformly the answer "object "prum.txt" not found". Which is the default directory for read.table() ?? Thanks! Z.

x-server
Dear all, first, I would like to thank R-core team for making so a great software available. Thank you all, really! Using R (1.0.0) on a Win98 platform, I need an x-server to run xgobi (through R xgobi interface). I've been using a MI/X server but trying to upgrade I noticed that MI/X is no longer available for free. Similarly, eXceed is available at evaluation version (for a limited time

R: machine for moderately large data
Dear all, I would like to ask your advice about a suitable computer for the following usage. I (am starting to) work with moderately big data in R: - cca 2 - 20 million rows * 100 - 1000 columns (market basket data) - mainly clustering, classification trees, association analysis (e.g. libraries rpart, cba, proxy, party) Can you recommend a sufficient computer for this volume? I am routinely

write list to ascii
Dear all, apologies for this (perhaps recurrent) question but I did not found a question when searching mailing lists. How to write a list of a simple kind, e.g.: abc <- list(one=(1:2), two=(1:5)) # to a file? I understand that write() & co. cannot work but when I try sink("aa.txt", append=T, split=T) abc sink() # the output is indeed "split by rows" in the

barplot
Dear all, do anybody know how to set ylim in barplot() correctly? When I write: > barplot(c(.1,.5,1.0)) the y-axis goes from 0.0 to 0.8. Wheny I type: > barplot(c(.1,.5,1.0,),ylim=range(0:1)) the y-axis goes from 0.0 to 0.8. Obviously I am doing something wrong. Are the ylim setting standards in barplot() other than in plot() or is this a bug? Thanks for any hints! Zdenek

Bland Altman plot (was: paste ?)
Dear all, sorry for this perhaps stupid question, but it concerns my recent problem as well as the current thread on B-A plot. I would like to plot something like x+y vs. x-y or mean(x,y) vs difference (x,y), but my "variables" x,y are actually pairs of replicates (two observed values of a growth rate by 60 clones). So the order x,y does not matter and each x,y pair can be arranged

Prediction with multiple zeros in the dependent variable
I have a batch of data in each line of data contains three values, calcium score, age, and sex. I would like to predict calcium scores as a function of age and sex, i.e. calcium=f(age,sex). Unfortunately the calcium scorers have a very "ugly distribution". There are multiple zeros, and multiple values between 300 and 600. There are no values between zero and 300. Needless to say, the

Hi all, I am using rw0632b on Win95 machine. When printing plots (both, as saved *.gif, and copied through clipboard) I get pretty low resolution.

Fwd: Re: Seeking help with trellis: log scales on xyplot
Deepayan: Sorry for the additional email, but I'm concerned that I wasn't being clear. In the end, I would like a graphic that portrays my y-values on a log scale in their native data range. That is to say, I would prefer to see the axis labels as 1000 rather than 3 (log10 of 1000). Thank you for your kind assistance, Hobie Perry St. Paul, MN Hobie Perry <hobie_perry@yahoo.com>

In Win95/NT you can use xgobi (program and R interface) as well, provided you will install an x-server on your machine (a free one is available from http://www.microimages.com/freestuf/mix/).

help wrapping findInterval into a function
Dear R Community, I hope you might be able to assist with a small problem creating a function. I am working with water-quality data sets that contain the concentration of many different elements in water samples. I need to assign quality-control flags to values that fall into various concentration ranges. Rather than a web of nested if statements, I am employing the findInterval function to
