Hi R-users I can not change the name of one column only of my matrix. my_matrix <- matrix (1:12,ncol=3) colnames(my_matrix)[1] <- 'myname' Error in dimnames(x) <- dn : length of 'dimnames' [2] not equal to array extent thank you for your help Lorenzo [[alternative HTML version deleted]]

Hello, I saw this nice trick I want to replicate but I lost the source and I hope one of you can point me to the solution. My problem is that I don't know the correct words to query this. When I print to screen a matrix or data.frame the columns are split and printed below the previous ones; even though I have plenty of screen left. E.g., > my_matrix = matrix(runif(30),nrow=3,ncol=10)

Hello Everyone, I am using R for creating heatmap from a square matrix. Below is my script to do so my_map <- read.csv("Desktop/input.csv", sep=",") my_matrix <- data.matrix(my_map) my_heatmap <- heatmap(my_matrix, Rowv=NA, Colv=NA, col = cm.colors(256), scale="column", margins=c(5,10)) I get a beautiful plot as output, but I could not save this plot

Hi, I have a comma separated file with element names in first column like shown below : Name_1,0 Name_2,0.8878,0 Name_3,0.6777,0.7643,0 Name_4,0.9844,0.1234,0.1414,0 Original data is a 10000x10000 symmetric matrix (600 MB). To reduce file size, I have minimized matrix to only lower triangle. Is there a (memory) efficient way to 1) read file 2) compute first and second principal components and

I think I figured this out. I should not have put the Driver name in braces.

Hello, This is another iteration of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version and drooped the support for PSTORE_TYPE_CONSOLE for simplicity. It'll be added once the basic implementation * changes in v3) - use QIOChannel API (Stefan, Daniel) - add bound check for malcious guests (Daniel) - drop support PSTORE_TYPE_CONSOLE for now

Dear All, While inverting a matrix the following error appears on my console: Error in solve.default(my_matrix) : Lapack routine dgesv: system is exactly singular With this respect, I have been replacing the solve() function with ginv(): the Moore-Penrose generalized inverse of a matrix. These are the questions I would like to ask you: 1. Would you also replace solve() with ginv() in

Hello R-Users! I'm using a heatmap to visualize a matrix of values between -1 and 3. How can I set the colors so that white is zero, below zero is blue of increasing intensity towards -1 and above zero is red of increasing intensity towards red? I tried like this (using the marray and gplots packages from bioconductor): mcol <- maPalette(low="blue", mid="white",

Hi all, I''ve got an issue where i have a search page that passes a field which is then used as the criteria of the search. Problem is, I''ve set an AR has_many relationship in the model that joins one table to another - both tables have the same column name I''m searching on, so naturally I get an ambiguous error in sql - it doesnt know which column to apply the search

Hi all, How can I decrease the number of ticks on the y-axis in a lattice levelplot()? I have as many ticks displayed on the y-axis as I have columns of data (1000 columns), how can I decrease this amount of ticks, while still properly displaying all the data? Note that I get my data from a matrix object, in which the z-values of the levelplot are the actual values in the matrix, whereas the

Hi all, I have a bunch of int vectors. Each vector holds a bunch of ints that correspond to row numbers of an existing matrix. I use the int vectors to pull out rows of data from a matrix, i.e. data <- my_matrix[int_vector,] I would like to store these int vectors in some sort of data structure that will preserve them as-is and allow iteration. I guess what I'm looking for would be

Dear R gurus, I'm trying to solve what I assume is a fairly simple problem, but I'm having trouble finding the proper approach. I have a matrix where each column is some object (e.g. a car) and each row is a numeric measurement of a feature of said object (e.g. horse power, top speed, etc.). Let's also suppose that I know what make the car is (e.g. toyota, ford, etc.), stored in a

I am sure I'm doing something wrong here but not sure what. Our system administrator recently installed UnixODBC and the MyODBC driver on a Linux box running Linux version 2.6 x86_64.
