Dear all, This seems like a simple problem but i've searched the help files and tried various options but failed, so apologies in advance for asking what i'm sure is an easy thing to do! In short, I have displayed behavioural data using the TraMineR package such that there is a colour change between the transition of behaviours, however, all the methods that i have used thus far have

Dear all. After much grief I have finally found the source of some weird discrepancies in results generated using R. It turns out that this is due to the way R handles multi-line expressions. Here is an example with R version 2.8.1: ---------------------------------------------------- # R-script... r_parse_error <- function () { a <- 1; b <- 1; c <- 1; d <- a + b + c; e

Hello, I'm trying to put a dynamic table and a dynamic graph side by side in a pdf document using Sweave. The data.frame used to generate the table is called rg (rg.txt): "Date"; "Code"; "Data1"; "Data2" "2009-03-10";"1";1958;147 "2009-03-10";"2";302;144 "2009-03-10";"3";4;141

if I want to put fig1plot to the left, figYPplot to the right figYAaplot on the bottom. How to modify the following cod to do these? \begin{figure}[H] \centering \begin{minipage}[t]{0.5\textwidth} \centering <<label=fig1plot,fig=TRUE,echo=FALSE>>= <<fig1plot>> @ %\caption{Caption 1} \end{minipage} \begin{minipage}[t]{0.5\textwidth} \centering

Hi I am relatively new to R and am trying to figure out to plot 3d scatter plot using defined colors based on x-axis and y-axis values. Right now in the code below, I assign colors based on certain values in the names of the x-axis. Now if I want to extend the condition to assign a color based on the names of both x-axis and y-axis values, what should I be doing? Any help or ideas would be

Dear R gurus and users, for some functions in some of the many packages available for R, with the current definition of \Header given in Rd.sty, the heading bumps into the surrounding words in documentation printed via LaTeX. To alleviate this minor typographical mishap, I'd like to suggest the change to R/doc/manual/Rd.sty included below as a context diff. With this minor diff applied, the

Hi, I was trying to make a density plot with 13 samples. To distinguish each sample, it would be good if each color is as different as possible from the other colors. I could use the built in function, but that does not do more than 8 colors and then goes back to recycling the cols. If I use a palette, then it is really difficult to distinguish between the colors. So, is there a way that I can

R-help, I'm trying to read a data file with plenty of columns. I just need the first 5 but it doe not work by doing something like: > mycols <- rep(NULL, 430) ; mycols[c(1:4)] <- NA > read.table(myfile, skip=2, colClasses=mycols) Any suggestions? Thanks in advance

Hi Paul, Take a look at gam() from package mgcv (gam = generalized additive models), maybe this will help you. GAMs can work with other distributions as well. Generalized additive models consist of a random component, an additive component, and a link function relating these two components. The response Y, the random component, is assumed to have a density in the exponential family. I am not sure

Hi! I am new to R just 3 days in it and i apologize if my questions seem very trivial and consumed your valuable time. I am coding in perl and i stumbled upon R regarding plotting good statistical graphs. I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried the example code given in the tutorial to perform 2d plot # i ranges from 2 to 10 cl <- kmeans(x, i, 20)

Hello, everybody: I'm back to share a long piece of example code. Because I had trouble understanding the role of par() and margins when customizing barplots, I have struggled with this example. In case you are a student wanting to place legends or textual markers in the outer regions of a barplot, you might run these examples. There are a few little things I don't quite understand.

It was recently pointed out by Wacek Kusnierczyk that although one is prevented from doing FALSE <- TRUE one *can* do assign("FALSE",TRUE) and have an object named ``FALSE'' with value TRUE in one's workspace. This apparently has no deleterious effects; e.g. doing sample(1:7,replace=FALSE) gives a random permutation of 1:7 as expected and desired. I.e. the local

Hello, I am wondering about the behaviour of strsplit. When the pattern matches the beginning of the search string, the mepty string is added to the result, but that's not the case when the pattern matches the end of the search string: strsplit(" hello dolly ") [1] "" "hello" "dolly" The man for strsplit explains the algorithm: " The algorithm
