Dear all, I am trying to extract rows from a data.frame based on the rowSums != 0. I want to preserve rownames in the first column in the subset. Does anyone know how to extract all species that don't have rowSums equal to zero? Here it is: # dataset x <- data.frame( species=c("sp.1","sp.2","sp.3","sp.4"), site1=c(2,3,0,0), site2=c(0,0,0,0),

Hi, In my data set I have created a matrix of distances. How can I get a list of minimum value in each row? thanks a lot, Rog?rio

I think the problem is the way files are named on the Macintosh. On the Mac, the file separator character, which is "/" on unix and "\" on dos/windows, is ":". Also, the root directory doesn't start with the separator character, but instead just starts with the volume name, which is the name of the hard disk icon on your desktop, so if your file is in the top

I am trying to use the function gl (generate levels), and would like to make levels with different number of replications. Does anyone know how to generate different number of replications in each level? Something like: [1] Site1 Site1 Site1 Site1 Site1 Site1 Site1 [8] Site2 Site2 Site2 Site2 Site2 Thanks in advance -- Rog?rio R. Silva MZUSP http://www.mz.usp.br Linux/Debian User # 354364

Airon, I used R2.4.0 on a Windows XP (SP2) (not Chinese :-)) and it still works: > data = read.csv("u:/airon.csv") > xdata = data$Adj..Close > modwt.la8 = modwt(xdata, "la8", n.level=6) > summary(modwt.la8) Length Class Mode d1 1467 -none- numeric d2 1467 -none- numeric d3 1467 -none- numeric d4 1467 -none- numeric d5 1467 -none- numeric d6 1467

Airon, I don't think you have to find an English computer 'cause the following must work in your Chinese one :-) Let me explain. First of all, change your lines to xdata <- ckhdat$Adj..Close[1:1447] #names(ckhdwt.la8) <- c("w1", "w2", "w3", "w4", "w5","w6", "v6") note the # sign, i.e., DO NOT change the names

Dear all As part of an ongoing study on the ecomorphology of ant communities, I have obtained a matrix with 156 row (species) and 20 columns (several measurements of body shape) for 4 localities. For each community, I calculated a matrix of Euclidean distances between all pairs of species. From this matrix, I extracted two measures of community structure: i) I identified the distance from a

Hello all. I have a large .txt file whose variables are fixed-columns, ie, variable V1 goes from columns 1 to 7, V2 from 8 to 23 etc. This is a 60GB file with 90 variables and 60 million observations. I'm working with a Pentium 4, 1GB RAM, Windows XP Pro. I tried the following code just to see if I could work with 2 variables but it seems not possible: R : Copyright 2005, The R Foundation

Dear List, I've around 1000 *.txt files, I've generate with other software. I've now done the following code (below). My question is how can I automate this (with do.call () ?), so it could be done for all the *.txt files. Thanks in advance, Rog??rio names<- list.files() file <- "BLU_Var_%04d.txt" for(i in 1:1000){

Hi all. I'm trying to numerically invert the characteristic function of a quadratic form following Imhof's (1961, Biometrika 48) procedure. The parameters are: lambda=c(.6,.3,.1) h=c(2,2,2) sigma=c(0,0,0) q=3 I've implemented Imhof's procedure two ways that, for me, should give the same answer: #more legible integral1 = function(u) {

Dear List: I have the following simple program: x<- sample(site) VarGuilda1<- var(tapply(x,site,func1)) VarGuilda2<- var(tapply(x,site,func2)) VarGuilda3<- var(tapply(x,site,func3)) VarGuilda4<- var(tapply(x,site,func4)) VarGuilda5<- var(tapply(x,site,func5)) VarGuilda6<- var(tapply(x,site,func6)) VarGuilda7<- var(tapply(x,site,func7)) VarGuilda8<-

I''d like to make a suggestion to the Advanced Routing HOWTO. I have read parts of it some months ago and I had a hard time following it and I think that I know the reason: the HOWTO doesn''t give the background on the subjects it discusses. This difficulty was particularly evident when I was reading the part about Quality of Service/Bandwidth Shaping. I got the impression

Rowland, it was a typo. Sorry, I paste the smb.conf twice. I changed the smb.conf as you proposed, so: dns forwarder removed - yes it's in named.conf, and ntlm auth / lanman auth removed. I also checked the NTLMv2 configuration in windows XP. But the error is still there. I guess it's MIT as saw this in log: /usr/lib/mit/sbin/krb5kdc: kerberos: 10 But how can I confirm which kerberos

Hi List, I have an unusual problem concerning the Windows XP "Rotate" image explorer shell extension. I have a share called "Archives" defined with a number of sub-directories. Whilst I have read/write permission to all directories, I am unable to use the Windows XP "Rotate Clockwise" or "Rotate Counter Clockwise" image command on JPG's contained

Hi, I'm wondering why when I use --size-only on the same file, except the modification time, rsync transfers the modification time? I was under the impression that --size-only caused rsync to transfer files based upon differences in the size of the file. For example: #cp Untitled.pdf Untitled-2.pdf #touch Untitled.pdf #rsync -ani --size-only Untitled.pdf Untitled-2.pdf .f..t......
