Hello, I have a matrix of 17 rows and 20 columns. I want to replicate this matrix 20 times, but I only want to replicate the rows. How do I do that?

Dear subscribers, I have made a simulation using loops rather than apply, simply because the loop function seems more natural to me. However, the current simulation takes forever and I have decided - finally - to learn how to use apply, but - as many other people before me - I am having a hard time changing habits. My current problem is: My current code for the loop is: distances <-

Dear R-users, I would like to process some spectroscopic data with R, and I was hoping some people might have some example code on how to do this. I would like to be able to do the following things: * Detect outlier-spectra -> This can be done by using scoreplot from the pls package * Determine the range of the spectrum to be used -> For this, I should be able to calculate the regression

Hi I installed R 2.2.0 from source and I have the packages for tcl and tk installed on my system, but the package tcltk says, when I try to load the library tcltk: Tcl/Tk support is not available on this system. Are there any settings / variables which I have to set so that R recognises that Tcl/Tk support is installed on the system? Rainer -- NEW TELEPHONE NUMBER Tel: +27 - (0)72 808

Hi all, I am doing some clustering and the clustered results are presented in a "pairs" plot showing 4 clusters... I made the data points belong to 4 different clusters displaying different colors. Now I want to select the best clustered class, how can I click on the data point, and the program returns the index of that cluster(its class number, or color number)? Also, if I would

How can I write a text, such as a result of a function or an explanation to a graphic device? When I try plot, I'm unable to reduce the axes. Greetings torsten

Hi! I'm translating some code from Matlab to R and I found a problem. I need to translate Matlab's function 'lsqnonlin' (http://www-ccs.ucsd.edu/matlab/toolbox/optim/lsqnonlin.html) into R, and at the beginning I thought it would be the same as R's 'optim'. But then I looked at the definition of 'lsqnonlin' and I don't quite see how to make

Hi I have a square matrix Ainv of size N-by-N where N ~ 1000 I have a rectangular matrix H of size N by n where n ~ 4. I have a vector d of length N. I need X = solve(t(H) %*% Ainv %*% H) %*% t(H) %*% Ainv %*% d and H %*% X. It is possible to rewrite X in the recommended crossprod way: X <- solve(quad.form(Ainv, H), crossprod(crossprod(Ainv, H), d)) where quad.form() is a little

Hello all I am playing with R for to make a animated GIF. any suggestions, improvements are welcome :-) case somebody could help me, i thanks! Cleber N. Borges ( klebyn ) my objective: (steps TODO) ------------------- 1) to save PNG files; -----> i don't know the best way to make this; 2) transform the PNG files into GIF files (easy! no problem! ... i think ...) 3)

Hi, I?m trying to get smooth curves connecting points in a plot using "spline" but I don?t get what I whant. Eg.: x<-1:5 y <- c(0.31, 0.45, 0.84, 0.43, 0.25) plot(x,y) lines(spline(x,y)) Creates a valley between the first and second points, then peaks at 3rd, and another valley between 4th and 5th. I?m trying to get a consistently growing curve up to the 3rth point and then a

Hello R folks, Reproducible code below - I'm trying to do a weighted mean by a factor and can't figure it out. Thanks in advance for your assistance. Mike data<-data.frame(c(5,5,1,1,1), c(10,8,9,5,3), c("A","A","A","B","B"))

Hello, I'd like to transpose data to create an analysis-friendly dataframe. See below for an example, I was unable to use t(x) and I couldn't find a function with options like PROC TRANSPOSE in SAS. The ideal solution handles variable quantities of SITE - but beggars can't be choosers. :-) Thank you in advance, Mike ## INPUT DATA USER_ID<-c(1,1,1,2,2,2,3,3,4) SITE

Fellow R programmers, I'd like to submit SQLDF statements with R objects as column names. For example, I want to assign "X" to "var1" (var1<-"X") and then refer to "var1" in the SQLDF statement. SQLDF needs to understand that when I reference "var1", it should look for "X" in the dataframe. This is necessary because my SQLDF

Hi, thx for the reply. Unfortunately that is not a simplified version of the problem. You have a function, call it and get the result (numeric in, numeric out in that case). For simplicity lets use the "return" case: ## foobar<-function(x) { return(sqrt(x)) }(2) ## which is a function (numeric in, numeric out) which is defined, then gets called and the return value is a function

Morning everybody, I am still using good old joe editor on my CentOS machines although it is no longer included in the CentOS repositories. Is there any comparable "wordstar" compatible editor that is part of the standard distribution? And no, I don't want to use Emacs. :-) best regards --- Michael Schumacher

Hello. I was writing some code that computes on the language and came across this. I can work around it, but thought you might like to know about it. > f <- function(x) { NULL } > a <- as.list(f)[[1]] > a # ie print(a) Error: argument "a" is missing, with no default Note it says *argument* "a", which is strange. In fact, and unsurprisingly, the bug lies with
