I have found an existing image on Amazon EC2 including R. But unfortunately, it is 32-bit R on 32-bit Linux. Does anybody know if there exists an mage (R 64-bit on Linux 64-bit) on Amazon EC2? Or how can I install 64-bit R on my own Linux instance there? Thanks. -- View this message in context:

Dear R buddies, I’m trying to run Principal Component Analysis, package princomp: http://stat.ethz.ch/R-manual/R-patched/library/stats/html/princomp.html. My question is: why do I get different results with pca = princomp (x, cor = TRUE) and pca = princomp (x, cor = FALSE) even when I standardize variables in my matrix? Best regards, Blaž Simčič [[alternative HTML version deleted]]

It would appear that Samba <-> Samba across subnets works fine, but Samba <-> NT is a problem. Does anybody else concur with this statement? Specifically, running Samba 1.9.18p10 (Solaris) and directing all password authenication to an NT server on a subnet causes the following output in the log file: ---------------------------------------------------------------------------

#This is probably due to my incomplete understanding of grep, but the below code has been working for some time to #search for .R with anything in front of it and return a list of scripts to source. Likely, the syntax for the #grep statement has been wrong all along. scripts2source <- (c("/home/ssefick/R_scripts/Convert_package.R",

Hi, I am trying to get a summary of the counts of different variables for each sample in a matrix of the form "m" below to generate an output as shown. (Ultimately I want to generate a stacked barchart for each sample). I am only able to get the "table" function to work on one sample (column) at a time. Any help appreciated. Thank you Sarah   a<-c("A",

Hi, I am trying to format some data (example matrix "m" below) for which each data point has 2 associated values separated by a comma. I want to replace values <3 with "0" to give the example output below. I have got as far as: out<-lapply(strsplit(m,","),as.numeric) Failed to identify anything along the lines of "[out<3]<-0" that works... Thank

Hello, I have a dataframe (tab separated file) which looks like the example below - two values separated by a comma, and tab separation between each of these. [,1] [,2] [,3] [ ,4] [1,] 0,1 1,3 40,10 0,0 [2,] 20,5 4,2 10,40 10,0 [3,] 0,11 1,2 120,10 0,0 I would like to calculate the percentage of the smallest number separated by the comma by: 1) summing the values e.g. for

Dear R users, I am encountering a x axis labeling problem on quite basic plots... I use the following code which displays the labels on the x-axis with a 45 degrees angle: p <- plot(myobject1, type="b", col="red",cex=1, lwd=2, axes=FALSE, ann=FALSE, ylim=c(0,70)) title(main="title", font.main=4) axis(side=1, lab=F) text(axTicks(1), par("usr")[3] - 2,

I would like to randomly shuffle a distance object, such as the one created by ade4{dist.binary} below. My first attempt, using sample(jc.dist) creates a shuffled vector, losing the lower triangular structure of the distance object. How can I Ishuffle the lower triangular part of a distance matrix without losing the structure? Thanks. --Dale x1 <- c(rep(0,4),1) x2 <- c(rep(0,2),rep(1,3))

Hi, everyone When I ran this cript, There is Error in substring(tmp.subject, tmp.end[ex] + 1, tmp.start[ex + 1] - 1) : invalid substring argument(s) Could someone figure out what the problem is? for(i in 1:length(genebody[,1])){ tmp.id<-as.vector(genebody[i,1]) # get gene id tmp.subject<-as.vector(genebody[i,2]) # get gene sequence

Hallo, I just followed the discussion of the title: minimum from matrix. I have a similar problem. > a=matrix(c(0,2, 0, 0, 1, 3, 0, 3, 2, 0, 3, 5, 0, 4, 0, 0),ncol=4) > a=rbind(a,1:4) > a [,1] [,2] [,3] [,4] [1,] 0 1 2 0 [2,] 2 3 0 4 [3,] 0 0 3 0 [4,] 0 3 5 0 [5,] 1 2 3 4 > > minOfColumns=apply(a, 2, function(x)

I would like to be able to grab x and y columns out of a dataframe and then grab all of the columns that are not equal to x or y. I am sure that I am missing something easy. ftbr_UTM_downstream <- (structure(list(site = c("Jennie_Creek_Main_Stem", "Wolf_Pit_Creek_Main_Stem", "Little_Rockfish_Main_Stem_North", "Big_Muddy_Creek_Main_Stem",

I have a model Q=K*A*(R^r)*(S^s) A, R, and S are data I have and K is a curve fitting parameter. I have linearized as log(Q)=log(K)+log(A)+r*log(R)+s*log(S) I have taken the log of the data that I have and this is the model formula without the K part lm(Q~offset(A)+R+S, data=x) What is the formula that I should use? Thanks for all of your help. I can provide a subset of data if necessary.

Hello all, We have been working on the idmap_rfc2307 solution for this. Packet traces on the Samba server and the LDAP server don't show any communication between Samba and the LDAP server at any point. (Configuration below). Samba logs are set at 10 and the error message is consistent: ../../source3/auth/auth_util.c:1946(check_account) check_account: Failed to convert SID

Hi, I have a data frame with one column containing string of the form "ABC...|XYZ..." where ABC etc are fields of 6 alphanumeric characters each and XYZ etc are fields of 8 alphanumeric characters each; "|" is a mandatory separator; I do not know in advance how many fields of each kind will each row contain. I need to extract these fields from the string. === How do I do that?

Dear R-users, I did some more research and I'm still not sure how to set up an ANCOVA with nestedness. Specifically I'm not sure how to express chicks nested within boxes. I will be getting Pinheiro & Bates (Mixed Effects Models in S and S-Plus) but it will not arrive for another two weeks from our interlibrary loan. The goal is to determine if there are urbanization (purban)

Hi. I'm trying to plot the ratio of used versus unused bird houses (coded 1 or 0) versus a continuous environmental gradient (proportion of urban cover [purban2]) that I would like to convert into bins (0 - 0.25, 0.26 - 0.5, 0.51 - 0.75, 0.76 - 1.0) and I'm not having much luck figuring this out. I ran a logistic regression and purban2 ends up driving the probability of a box being
