similar to: using for variable as rowname

Hi, My first post here and new to R so please bear with me (long time programmer though, helping a friend with some scripts). I've noticed a behaviour when using rownames() that I think is odd, wondering if I'm doing something wrong. To illustrate, say I create a very simple matrix (called fred): fred<-matrix(,4,2) It looks like this: [,1] [,2] [1,] NA NA [2,] NA NA

Hi, I've a matrix that contains 4 replicates of each rowname. (4 a's, 4 b's, 4 c's in no particular order) Like this: # c 32 a 1 b 4 c 87 c 34 b 54 a 23 a 12 b 9 a 3 b 87 c 43 There are a couple of more columns but I'm using the above as an example I need to sort it so that the same rownames appear together in alpahbetical order. Like this: # a 1 a 23 a 12 a 3 b 4

Hi I want to extract rows of a matrix, and preserve rownames even if only one row is selected. Toy example: R> a <- matrix(1:9,3,3) R> rownames(a) <- letters[1:3] R> colnames(a) <- LETTERS[1:3] R> a A B C a 1 4 7 b 2 5 8 c 3 6 9 Extract the first two rows: R> wanted <- 1:2 R> a[wanted,] A B C a 1 4 7 b 2 5 8 rownames come through fine. Now extract just

All, I'm currently using R 2.0.1 on a Powerbook G4 with OS X 10.3.8. So far the only way I've found to set my proxy is by doing Sys.putenv("http_proxy"="<insert proxy url>:<proxy port>) everytime I start up R. This works fine, but I'd like to find a solution that doesnt require manual input everytime I start up R. Does any one have a better way of

Has anyone else ran into problems installing Rggobi with R 2.0.1 on a windows platform? I've followed all the instructions available and I still can not get R to recognize Rggobi as a library (package). I I've already emailed Duncan Temple Lange at ggobi.org and bell labs and both emails have bounced back. Any help would be greatly appreciated. -Drew Balazs

Dear users, please help to define the following data structure: I would like to have a matrix, where every element is a container of different size , containing real numbers.

The containers are initially empty, I would like to fill them

Hi everyone, I am trying to conduct a synthetic control analysis using the MSCMT package. However, when trying to run it I get a very cryptic error message saying "Error in lst[[nam]][intersect(tim, rownames(lst[[nam]])), cols, drop = FALSE]: subscript out of bounds".

Hello ! I am attempting to switch from being a long time SAS user to R, and would really appreciate a bit of help ! The first thing I do in getting a large dataset (thousands of obervations and hundreds of variables) is to run a SAS command PROC CONTENTS VARNUM command - this provides me a table with the name of each variable, its type and length; then I run a PROC MEANS - for numerical

Apparently there is one or more concepts that I do not fully understand from the descriptions of a function and the apply material. I have been reading the mail from this forum and have learned much but, in this case, what I have been reading here and from the manual isn't enough. The following code produces what I want with the for loop. From what I have read from this forum, a for

predict.lm keeps row names when working from several rows in newdata, but always removes rowname from a single row. The rownames are removed by the line in predict.lm predictor <- drop(X[, piv, drop = FALSE] %*% beta[piv]) What is the reason for that decision? I usually want to retain the row names. tmp <- data.frame(x=1:4, y=c(1,3,2,5)) tmp.lm <- lm(y ~ x, data=tmp) tmp.new <-
