I wanted to print the first and last rows of some dataframes in Sweave using dots in columns to separate the two parts. Head and tail almost work, but I have problems with factors and row names. z<-data.frame(id=letters[1:26], x=sample(1:26,26)) rbind(head(z,3), ".", tail(z,1)) id x 1 a 18 2 b 8 3 c 14 4 <NA> . 26 z 10 Warning message: invalid

Hi, I would like to construct a transition matrix from a data frame with annual transitions of marked plants. plant<-c(1:6) class<-c("seed","seed", "seed", "veg", "rep", "rep") fate<-c("dead", "veg","veg","rep", "rep", "veg") trans<-data.frame(plant, class, fate)

Hi, I need to resample rows in a data frame by subsets L3 <- LETTERS[1:3] d <- data.frame(cbind(x=1, y=1:10), fac=sample(L3, 10, repl=TRUE)) x y fac 1 1 1 A 2 1 2 A 3 1 3 A 4 1 4 A 5 1 5 C 6 1 6 C 7 1 7 B 8 1 8 A 9 1 9 C 10 1 10 A I have seen this used to sample rows with replacement d[sample(nrow(d), replace=T), ] x y fac 7 1 7 B 2

I'm trying to read some web tables directly into R. These are both genome sequencing projects (eukaryotes and metagenomes) from NCBI and look very similar; however, only the first one works. http://www.ncbi.nlm.nih.gov/genomes/leuks.cgi http://www.ncbi.nlm.nih.gov/genomes/lenvs.cgi I added ?dump=selected to the end of the url string to get a tab- delimited file (which is what happens

Dear R-helpers: thank your for your attention. i am a newer to R and i am doing some protein category classification based on the amino acid sequence.while i have some questions urgently. 1. any packages for analysis amino acid sequence 2. given two sequences "AAA" and "BBB",how can i combine them into "AAABBB" 3. based on "AAABBB",how can i get some

Hey All, I have a dataset(dat1) like this: ObsNumber ID Weight 1 0001 12 2 0001 13 3 0001 14 4 0002 16 5 0002 17 And another dataset(dat2) like this: ID Height 0001 3.2 0001 2.6 0001

If anyone has a list of application areas where there is extensive use of R, I'd like to hear of it.

Scott Wilburn" <wilburn at lanl.gov> To: ssh at clinet.fi Subject: F-secure -> Openssh Compatibility We have Macintoshes running Fsecure SSH client 1.0.1 which are unable to connect to a server running Openssh 2.1.1 on Red Hat 6.2. I believe that the problem is a bug with Fsecure, since a 30-day trial version of 1.0.2 works

I also downloaded the rgl package (after reading recent Uwe Ligges' post) and installed in on my Win2k Pro sp2 machine. It seems to work with no problems. I ran most of the examples, including the hist3d one, and all of them worked fine. A couple of thoughts. I have administrative priviliges on my machine. Could this possible make a difference. The rgl library uses OpenGL. Is it a

Good Day, Included below is some code to generate data and to fit a mixed effects model to this fake data. The code works as expected when I call the function "lme" in Splus but not in R. The error message from calling lme in R is: "Error in getGroups.data.frame(dataMix, groups) : Invalid formula for groups" I installed the nlme package for R around 20 August

O.K. I know it was too late to make changes for the next release, but thankfully there werent any changes needed. Kerberos over ssh protocol 1 worked out of the box from CVS today (2002/10/04-14:30) The krb5 patches we were using (I think from Olaf K) was all in the code. The only thing I had to patch to get things working was removing the scard-install from the Makefile.in The compiled code

I'm new to this list, so please forgive me if this has been discussed before. It appears that one of the (commendable) design goals of OpenSSH is to re-use existing open-source libraries wherever possible in order to simplify the OpenSSH code and hopefully improve security in the process. As exhibited by the current, non-open SSH, supporting all of the nuances of authentication and logins

I wrote a package which includes a number of genome sequencing project statistics on the web like http://www.ncbi.nlm.nih.gov/genomes/lproks.cgi. I included some generic functions to summarize, plot, and update the tables with the most recent version data(lproks) update(lproks) [1] "lproks successfully updated, 7 new genomes added" I usually save the dataset back to my package

Hi, In Splus if I call the function crosstabs() the output is a contigency table; in each cell of the table is printed: N, N/RowTotal, N/ColTotal, N/Total. N is the number of observations in each cell. The same call to xtabs() in R will produce the contigency table but the only entry in each cell is N. How can I get the same relative frequencies that crosstabs() gives? Thanks, mike --

Hi, everyone, The paper submission deadline for this year's LLVM in HPC workshop has been further extended to September 14th (AoE). We're looking for a few additional submissions, so if you have anything that could be submitted as a paper by the beginning of next week, please take advantage of this opportunity. If you have any questions, please let me know. SC20 is now a virtual

Reminder for Mac Puppeteers going to WWDC How about we meet for lunch at noon on Tuesday. Let''s try to get the table closet to the Odwalla refrigerator, just for reference. We can get more specific on this list on the 8th after we verify the set up. I might even get there a little earlier and put down "reserved" tags. --- Thank you, Allan Marcus Solutions Architect Central

Hello, I have data frames X1 to X19 I want a simple way to bind them as the next run(s) will generate many more sequential data frames. I tried the following with i = 19: > my.list <- as.list(paste("X",1:i,sep="")) > new.data <- do.call("rbind", my.list) > new.data [,1] [1,] "X1" [2,] "X2" [3,] "X3" [4,]

Hello, I would like to convert an objects list such as objects() or ls() that outputs "a101" "a102" "a104" "a107" "a109" to read within a list statement as follows : list(a101,a102,a104,a107,a109) Thanks Tony
