I have a matrix of, say, M and N dimensions: my_matrix=matrix(c(1:60),nrow=6,ncol=10) I have two "id" vectors corresponding to the rows and columns, e.g.: id_m=seq(10,60,by=10) id_n=seq(100,1000,by=100) I would like to create a "proper" database (let's say a data.frame for this example -- i'm going to be loading these into an SQLite database, but we'll leave

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, I have 2 functions (a and b) a = function(n) { matrix (runif(n*2,0.0,1), n) } > > > b = function (m, matrix) { > n=nrow (matrix) > p=ceiling (n/m) > lapply (1:p, function (l,n,m) { > inf = ((l-1)*m)+1 > if (l<p) sup=((l-1)*m)+m > else sup=n >

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

Hi I am using igraph package in R. My goal is to read a network (in "pajek" format) and decompose the network into components. In addition, I am also interested in sending this output to to a file. I am having problem in while writing to a file! my code looks like this g <- read.graph ("F://test.net", "pajek") compo <- decompose.graph(g,

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, 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 created a GlobalVariable from a ConstantArray. I then used to the setSection() method on my GlobalVariable. Looking at the ELF file it does not look like it is where I specified. I gave "new StringRef("my_map")" to the method. Is there more that needs to be done? In case it matters this is ToT on Linux. Thank you

Hi there, Could anyone please help me to understand what should be done in order not to get this error message: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?

Hi, Shorewall version -4.0.12-2 (EL5 rpm version) OS : Centos 5.2 I have shorewall successfully running on Linux with multi ISP. Trying to make services such as "rsync, ftp" go through my secondary ISP. For which I did the following eth0 : Internal LAN eth4 : DSL (Second ISP) => x.x eth5 : T1 (First ISP) => y.y Created the following entries in

I am using shorewall-4.2.5-1 on RHEL-5.2 for a MultiISP connection. Everything works great. I run vpn, proxy, mail relay on the firewall. Hence I do the application level management. So far I was using third party script "gwping" for my failover mechanism. Just wondering if shorewall has any native programs to handle fail over ? Thank you Chakri

Hi, I wrote a program in PERL which creates a file with .net extension (.. xyz.net). I want to call R from within my PERL program, execute 3-line command in 'R', store the output and get back to PERL program. RSPerl is of omegahat is a good software which creates interface between R and PERL, but unfortunately it doesn't work on my Windows XP. I used the following command in PERL to

Hi all and specially Mr. Tom.... (Please, do not be acid with me please! I am only a newbie, trying learn more about shorewall) I get involved with a Firewall Project in a customer here in my city... In this customer, he has two Internet Providers. So, he ask me how make certain connection following one routing path (like RT_1) and others connections type, following the other routing path
