I would say this was user error (insisting on editing non-existent rownames), although the argument is documented. You could argue that there are implicit rownames, but they would be 1, 2 ... not row1, row2 .... And rownames(mat) is NULL. For an interactive function the best solution seems to be to throw an error when the user asks for the impossible. I'll fix it for 2.7.0: it

Ben, Thanks for the bug report. I am off two minds about it as discussed below. But as it does indeed create a crash / segfault, I am passing this on to the R bug tracker. A suggested two-line patch is below; I tested the patch against a 'vanilla' 2.6.1 source tree.

I guess this has a simple solution: I have matrix 'mat1' which has row and column names, e.g.: A B C row1 0 0 0 row2 0 0 0 .... rown 0 0 0 I have a another matrix 'mat2', essentially a subset of 'mat1' where the rownames are all in 'mat1' e.g.: B row3 5 row8 6 row54 7 I want to insert the values of matrix mat2 for column B (in reality it could be some or

Hello, I still can't figure out why my users' passwords are expiring. Ever since we switched to LDAP, passwords expire every 14 days.

All, I frequently make spreadsheets in Excel in which I rank values in columns by stop-light colors (red is bad, yellow is OK, green is good). Image and heatmap expect a matrix in which all the data are in the same scale, but I frequently have different scales in different columns. ie. Column one runs from 1-10 while column 2 runs from 1-100. I thus need to define a separate color ramp for each

Hello, We are using Samba 3.0.14a-6, slapd 2.2.26-4 and smbldap-tools 0.9.1-2 on Debian. My users are complaining about warnings that their password is about to expire and that the are told "You do not have permission to change your password" when they try to change it. sambaAcctFlags includes the X flag which I thought meant "don't expire passwords."

Hi All, I''m a super newbie with Prototype and am trying to implement my first solution using it. This is my code: var span = ''totalViews'' + video_id; var params = ''video_id='' + video_id; Ajax.Response(''trackVideo.php'', { method: ''post'', parameters: params, onSuccess: function(transport) {

Hi R Users, I'm trying to plot a stacked barplot. Here is data: Sample Col1 Col2 Col3 Row1 -2 4 -1 Row2 3 -2 4 Row3 3 5 -2 Row4 4 1 -1 I'm using following R code: library(lattice) dta<-read.table("data.txt", header=TRUE, row.names="Sample") barchart(data.matrix(dta), horizontal=FALSE, stack=TRUE, col=2:4,

Hi all, So let's say I have a matrix, mdat and I only know the index number. How do I retrieve the column and row names? For example, > mdat <- matrix(c(1,2,3, 11,12,13), nrow = 2, ncol=3, byrow=TRUE, dimnames = list(c("row1", "row2"), c("C.1", "C.2", "C.3"))) > mdat[4] [1] 12 >

I'm running into a problem I can't seem to find a solution for. I'm attempting to add sequences into an existing data set based on subsets of the data. I've done this using a for loop with a small subset of data, but attempting the same process using real data (200k rows) is taking way too long. Here is some sample data and my ultimate goal >

Hi R-experts, I try to find a way to transfer a matrix to a data.frame that is used as input of aov. can you give me advice for that? >mdat <- matrix(c(1,2,3, 11,12,13), nrow = 2, ncol=3, byrow=TRUE, dimnames = list(c("row1", "row2"), c("Col1", "Col2", "Col3"))) >mdat      Col1 Col2 Col3 row1    1    2    3 row2   11   12   13 ===>

Hi, I have a data frame with several columns. Now I want to transfer the data into a new variable (also a data frame), but I only want a part of the data, defined by a rule ... for example; I have following data frame: row1 row2 row3 x 2 3 x 1 4 y 5 3 y 2 3 I know want a data frame, only with lines containing x in row1. I know how to do that for one row (f <-

Hi, I have a problem sorting and selecting entries within a data-frame and I don't know if it is possible to solve it with R ... (probably yes, but I have no idea how). Following Data; row1 row2 a 12 pos NA a 3 neg NA a 5 neg NA a 11 pos NA I want to extract the values in row 2 in the lines with an "a" in row1. But I want to have two vectors: vector x with all

Hi, I'm a bit puzzled. I uses exactly the same code in RcppExamples package to try adding RcppFrame object to RcppResultSet. When running it gives me segmentation fault problem.

Hi, I have an R programming problem and I havent found anything in the documentation yet: I have a data matrix, in which two neighbouring columns represent replicates of the same experiment, e.g. something like this: A A B B C C row1 1 1 1 2 2 2 row2 1 1 1 1 1 2 I would like to test, if the values for the two replicates in a row are the same or if they differ and generate a new

I would like to insert a few modest size data frames directly into my R code. a short illustration example of what I want is d <- read.csv( _END_, row.names=1 ) , "col1", "col2" "row1",1,2 "row2",3,4 __END__ right now, the data sits in external files. I could put each column into its own vector and then combine into a data frame, but this seems
