similar to: Dropping rows conditionally

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

Dear R Users; I am an R user who has recently bought a new laptop;Toshiba Satellite U405 running on both Windows Vista and Ubuntu. I have problems on the wondows vista when installing packages. The argument 'lib' is missing. How do i solve this problem? Illustration: > install.packages("epicalc") Warning in install.packages("epicalc") : argument 'lib'

Dear All, I installed R 2.7.0 and tried to call a dataset i had ealier own called on R2.6.2 but i keep on getting an error: use("maltreat.dta") Error in fromchar(x) : character string is not in a standard unambiguous format Tried doing the same with R2.7.1 but i get the same error. However if i call the same on R 2.6.2, there is no error: use("maltreat.dta") > des()

Dear Sir, I am almost giving up on getting the R-2.9.1 on the ubuntu 9.04 using the instructions found on the R site. I decided to use the R-2.9.1.tar.gz and untarred it. I then typed ./configure and the results are shown below. However, on typing make, I got an error, "No targets specified and no makefile found stop" What is the solution? lmramba at LMramba-dll-d:~$ su Password:

Dear all I am trying nlme together with Pinheiro/Bates book. I constructed grouped data object with suitable plotting layout (according to some common factor, panels from bottom to top are in increasing order). When I do nlme(... some stuff...) I get fitted object which I can plot with plot(augPred(fit.nlme6, level=0:1)) but it results in completely different ordering. Is there any way

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 >

Hello List, I am not sure that I have the correct terminology here (restricted bootstrap) which may be hampering my archive searches. I have quite a large spatially autocorrelated data set. I have xy coordinates and the corresponding pairwise distance matrix (metres) for each row. I would like to randomly sample some number of rows but restricting samples such that the distance between them is

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,

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

Hi guys, I have a matrix with values varying from approximately -0.7 to 0.33 that I want to create a heatmap/levelplot with. When I execute the levelplot function for my matrix, I end up getting colors that are adjusted to the max and min rather than around 0. In other words, ideally I would like to have a color ramp that goes from red (negative number), to white (0), to blue (positive);

Dear all, I have been running R-2.9.1 on Windows without any problem. I decided to run it on my Ubuntu 9.04 where i have R-2.8.1 and I have a problem loading the package JGR because it cannot load the dependancy rJava. This is a cool editor I would wish to use while on Ubuntu. Here is a copy of the errors i get: library(JGR) Loading required package: rJava Error in dyn.load(file, DLLpath =

Hi R Users, I'm using following data/code (data is also attached) to produce a stacked barplot. *I need help with changing legend boxes, currently I'm using "rectangles=TRUE". Is it possible to get small squares instead -- may be with a small gap between colored squares.* Currently there is no gap between the colored rectangles. # Sample Data: Names Col1 Col2 Col3 Row1 -20 40

Dear all, I have a large matrix with about 2500 variables, and 100 rows. I would like to calculate the means of the every 10 variables starting from 1:2500 and saving the results as a vector or matrix. How can I do that? Alternatively, How can I create 250 subset matrices in the order of variables 1:2500 in groups of 10 from the single matrix which had initially 2500 variables ? I guess I have

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 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
