Hello everybody, by the way, speaking about the r-cran-rcurl package in Ubuntu, the versions in trusty and vivid are linked by error to the "NSS" flavour of libcurl3 instead of the "OpenSSL flavour", which cause at least problems when using the CRAN devtools package. A bit more details are available in the Debian bug tracking system (https://bugs.debian.org/786473). I am not

Dear list, I realised by chance when analysing a 1521862 ? 8 matrix that plotting was much faster when using "." as the argument of `pch'. I was just wondering if there were other ways to get this speed improvement: it is otherwise quite difficult to explore such big matrices, especially given that X11 redraws the plot whenever its window is covered/uncovered by another window, or

Dear all, I am so ashamed to pollute the list with a trivial question, but it is a long time I have not used R, and I need a result in the next one or two hour... I have a table which I have loaded with read.table, and I want to make the mean of its columns. > slides <- read.table("slides.txt") > slides [1:5,] V1 V2 V3 V4 V5 V6 V7 V8 1

hi netters I have a rather simple question. I have a data frame with two variables X and Y, both of which are factors. X has 100 levels while Y has 10 levels only. The data frame has 100 rows in all, so for X the values are unique, and Y has many replicate values. Now I wanna reduce the data frame into 10 rows only, according to the 10 levels of Y. I don't care which value of X is in

Dear list, I hope it is not a FAQ, but I searched the archives and Google, and found nothing. The question is simple : I do not understand why, starting from a symmetrical correlation matrix, heatmap produces an asymmetrical image.

Hi all, I recently found out that R does not utilize fully the Duo Core capability when you only run one instance of R. I did some number crunching today and it seems that if I only open 1 R console, it uses 50% of my CPU (either 50-50 or 100-0 on 2 cores). Then, I open the second instance and divide the work into two parts, and run them parallelly, they seems to utilize 100% of my CPU. So, my

Hi Michael and Dirk, there are raising concerns that, as of today's computing power, an attacker can generate a GPG key that has the same short ID as a target key. In this situation, it may be possible that a user downloads and trusts the attacker's GPG key, and as a consequence installs malware. For that reason (better explained in http://lwn.net/Articles/697417/), it is recommended to

hi, when I used cbind to combine columns, some contents of columns has been replaced by number. in the script below, column should be aaa,bbb,ccc but I was given 1,2,3. but when I change the column to vector, it gave me correct contents. can you please tell me why?   > d<-read.table("aaa.txt") > d    V1  V2 1 aaa 123 2 bbb 345 3 ccc 986 > cbind(d[,1],d[,2])      [,1] [,2]

I'am a very fresh R user and I'd like to know how I could create such structures. I saw R was objects-oriented but I can not find any doccumentation on about how to build my hown ojects. Thanks.

Dear all, I wrote the following batch script on a iMac, and ran it on a linux mosix cluster. tu <- read.table("cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshape.table") tu_reshaped <- t(reshape(tu[1:50,], direction="wide", timevar="tu", idvar=c("rna","lib"))) write.table(tu_reshaped, "cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshaped.table")

Hi, I've just tried upgrading from 1.1.8 to 1.2.2. As soon as the new version was started up the number of imap/pop3 processes began to climb to 800+, where I normally have about 300 or so connections at any given time. The load on the server also climbed to 150+. I've reverted back to 1.1.18, which is running just fine, but is there anything I can do to help trace what was causing the

I have read in Paul Murrell's book R Graphics about how to use a bitmap as background for a plot (page 107). Also, I routinely use function read.shape() in package maptools to read maps in shapefile format. Now, I would like to overlay an aerial photograph in .jpg format and a map. I think I could do the alignment manually for each case, but wonder if there is a better, automated way. I notice

Hi! I am using R version 2.7.0 and am working on a panel dataset read into R as a dataframe; I call it "ex". The variables in "ex" are: id year x id: a character string which identifies the unit year: identifies the time period x: the variable of interest (which might contain NAs). Here is an example: > id <- rep(c("A","B","C"),2) >
