I hope this time I'm using the "iris" dataset correctly: ir <- rbind(iris3[,,1], iris3[,,2], iris3[,,3]) lir <- data.frame(log(ir)) names(lir) <- c("a","b","c","d") I'm trying to understand the meaning of expressions like "~ a+b+c+d", used with princomp, e.g. princomp(~ a+b+c+d, data=lir, cor=T) By inspection, it

Hi: Apologies for asking the following question. As?this may sound very basic and stupid for this forum?, I honestly do not know how to solve it and I do not have a teacher who can help me understand. ? I have list of genes (200)?that are involved in a particular process and I call this as a?ProcSet.?? From an independent experiment I found that out of 10,000 genes, 1500 are significant and I

dear group, i have a data matrix with some replicate items with different values. I want to extract the row with max value. for example: > x fruit weight 1 apple 1.3 2 apple 1.5 3 apple 1.6 4 orange 1.4 5 orange 1.6 x is a data frame. I want to extract unique items from fruits that has max weight. that is: 3 apple 1.6 5 orange 1.6 I want to be able to use

hi: I have matrix with dimensions(200 X 20,000). I have another file, a tab-delim file where first column variables are row names and second column variables are column names. For instance: > tmat Apple Orange Mango Grape Star A 0 0 0 0 0 O 0 0 0 0 0 M 0 0 0 0 0 G 0 0 0 0 0 S 0 0 0 0 0

I'm trying to export a large data frame to a text file for permanent storage. The only thing I could find was the treeglia Package but that didn't work. Any suggestions? Thanks! Christina D Smith PhD Student, GRA Statistics Department Kansas State University

hello: I am very confused when it comes to list operations in R. I seek help in the following problem. I have two different vectors myIDs - a character vector with no names to their elements x2 - another character vector derived from unlisting a list where an element has both a name and value. I am not happy the way x2 is with names and values to every element. > myIDs[1:10] [1]

It might be a bit faster to do matrix indexing: R> tbm <- as.matrix(tb) # turn it into a character matrix R> tmat[cbind(match(tbm[,2], rownames(tmat)), match(tbm[,1], colnames(tmat)))] <- 1 > tmat Apple Orange Mango Grape Star A 1 1 1 0 0 O 1 1 0 0 0 M 0 0 1 0 0 G 0 0 0 0 0 S 1 1 1 0

I have not had a great amount of success installing/updating packages from the "Packages" menu of Rgui under Windows XL. (Except for installing from loacal zip files.) But I am not asking for help in using these facilities because I prefer to keep a folder of package zip files. On the other hand I do find it tedious having to right-click "Save link as" on every individual

Dear group, I have a data.frame (d1) with various elements and a matrix (m1) created with NA (or 1s). I want to read each row,column in d1 and fill its numeric value in m1. Could some one help me because I have 130K rows and 500 column data.frame object and I was told that a for loop will take a long time. Thank you. > r1 <- c("A","A","B","B")

Hi experts, I am trying to write a very flexible method that allows me to add a new column to an existing data frame.

Hello Group, What is the meaning of the error. is there any place to look for this. I guess 'atomic' seems to be OOP related concept. thank you srini

Strange things. When I run the RxFAX command through an internally dialed extension, I can *hear* fax tones, meaning, I presume, that the RxFAX application is running. In fact, doing a show application confirms that. So, I'm presuming RxFAX application is talking as it should. However, inbound fax calls (tones) are not being detected. I know that my extensions file is corect. I am

Corect me if this is not the right place to post this. I have a mdbdriver.jar (to access an MSAccess file) under Linux. I bought the license from http://www.csv-jdbc.com/ guys. The driver work fine when tested with DBVisualizer or another JDBC thing. The problem is that driver needs 3 other more jar files to work. Under R I have tried this and does not work: > library(RJDBC) Loading required
