Dear list, I often need to convert several variables from numeric or integer into factors (before plotting, for instance), as in the following example, d <- data.frame( x = seq(1, 10), y = seq(1, 10), z = rnorm(10), a = letters[1:10]) d2 <- within(d, { x = factor(x) y = factor(y) }) str(d) str(d2) I'd like to write a function factorise() which takes a data.frame and

Hi, Why the qr() produces a negative Q compared with Gram-Schmidt? (note example below, except Q[2,3]) Here is an example, I calculate the Q by Gram-Schmidt process and compare the output with qr.Q() a <- c(1,0,1) b <- c(1,0,0) c <- c(2,1,0) x <- matrix(c(a,b,c),3,3) ########################## # Gram-Schmidt ########################## A <- matrix(a,3,1) q1 <-

Dear R users, please can you help me understand the behaviour of abline using function lm. I'm trying to learn linearity over groups. So I make three groups with 10 values each: test=data.frame(cbind( l=c(rnorm(10,0,30),rnorm(10,100,30),rnorm(10,200,30)), t = c(rep(0,10), rep(1,10), rep(2,10)) )) when I do: plot(test$l~test$t) abline(lm(test$l~test$t)) the abline is a straight line

Hello, I am a french student and I have written a technical report on an extension of the rsync algorithm to crypted files. I started from the situation of a client machine A user who doesn't wish to save an original file v0 and its successive versions v1 v2 v3 ... on a distant server B but rather to save the private ciphering of these files on the server. Let C be the cipher algorithm and

Hi, For some reason (outbound call tracking) I've got a few different outbound call process (using a macro for queuemetrics logging, or direct call) i wanted to factorise the routing process so i came up with something like the following. All in one it's working like expected, however every "ael reload" command trigger a lot of warning like that "application call

With the current implementation, the root inode of the given partition is ignored. The root inode is now reported. Its name will be a single dot '.' reproducing the TSK API.

Hello I tried a few searches on hist, histogram, equidist and space (space=0 was mentioned in one contribution), but none of that so far worked. It also says in the help "##-- For non-equidistant breaks, counts should NOT be graphed unscaled:" - which is precisely what I am looking for, but I cannot find it. I want to make a histogram using breaks which are spaced exponentially and in

Hi, I've been developing an application using CELT for some time and, for simplicity, have restricted frame sizes to powers of 2. During final testing I tested with a sound interface (the Phonic Firefly 302) whose ASIO drivers are very restictive in what they accept, and have about 6 allowable frame sizes < 512, a lot of which are odd numbers. However some are even numbered, so

In case more of you come across my request from this morning, I've already gotten several great tips, which I summarize here since one or two of these did not come across R-help as well. A team of fellow political scientists is on this problem like "white-on-rice"! Brandt, Patrick, John T. Williams Benjamin O. Fordham, and Brian Pollins. 2000. "Dynamic Modeling for Persistent

Hello everybody, so, here's the summary of my progress (note that it also includes a few items to discuss, so I'm cc-ing this to nut-upsdev as well). I. The planning: 1/ libnutconf: The core (i.e. config. classes and their (de)serialisers) is coded, UT in progress. Signalisation shall follow; I have a couple of practical thoughts & comments to this, see below. In general, I'd

Hi, I am trying to do a bayesian prediction for soil pollution data above a certain threshold, using geoR. Everything is working fine until i am doing the krig.bayes. I tried to do the prediction on a grid 67 by 113 cells and my computer is freezing to death. At larger numbers of cells it tells me after a while that it reaches the max. memory of 511 Mb. My computer has only 512 Mb of RAM.
