I am trying to create a set of vectors which have similar names. They have a common part and an extra unique part. I am sure I have seen questions on this before but I have been unable to find it in the archive. There are examples of sets of names for columns of a data frame, but not for individual vectors. Suppose I want vectors named myvar.1 myvar.2 etc. I tried: >

Hi all, I'm a potential new user of R and have to know this before I start using it: SPSS does not let you do a Post Hoc analysis on repeated measures data. This is a problem for me, since that is what I will have to do. Will R let me do this? /Fredrik -- ----------------------------------------------------------------- Fredrik Karlsson, Research Student Department of Philosophy and

Dear People, I have been trying to perform concatenation operations on lists without success. Consider the following example. > x <- runif(2) > y <- runif(2) > z <- runif(2) > xy <- list(x,y) > xyz <- list(x,y,z) I want to have a function foo such that foo(xy,z) is the same as xyz. This appears not to be as easy as I thought, though there must be a way. For example

Is there a quick way to make boxplots groups by two variables? By that I mean, that if x axes have values ("A","B","C"), than at each value there would be a few boxplots each for a value of second variable (say ("1","2","3")).

I have a problem, that the plot of mathematical formula sometimes crashes R on Linux (SuSE 6.2 and 7.0 on a Dual PIII/500 machine with 1GB RAM). The problem occurs for example in demo("graphics"), i.e. in the last part were the mathematical symbols are plotted. There are several circumstances to reproduce this segmentation fault, but the following is one of the most simple examples. The

Hi all, I have a problem which I am biting my teeth into unsuccessfully: (x <- data.frame(S1=c("a","b","d","F"),N1=c(2,4,6,9),N2=c(6,NA,0,6))) S1 N1 N2 1 a 2 6 2 b 4 NA 3 d 6 0 4 F 9 6 > is.na(x) S1 N1 N2 1 FALSE FALSE FALSE 2 FALSE FALSE TRUE 3 FALSE FALSE FALSE 4 FALSE FALSE FALSE No I want to be able to do: 1) Setting

Dear R-ers, somehow it is not possible to increase nsize to more than 20000k.

Hi, I know it must be written somewhere but I can't find it. I'd like to remove all variables or objects that I've created but not the functions. I look at a few things without success. Is there a R way of doing this? There are to many to create a manual list. Thanks in advance. Yves Gauvreau -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hello all, may be someone can give me a hint how to solve a little problem. I'm trying to create some expressions inside a for-loop which i want to evaluate AFTER this creation loop (but loop specific). To explain my problem here comes the code: y.mat <- t(matrix(rep(84:90,8) + as.numeric(gl(8,7)),nrow=7)) # > y.mat[1:2,] # [,1] [,2] [,3] [,4] [,5] [,6] [,7] # [1,] 85 86

In Matlab or Octave I can evaluate (evalf) the content of a string. In R I have looked around in the docs, but have not found a way to do something equivalent (which is possible, I think). Can anybody give me a pointer? ============================================================================= Thomas Hoffmann, Institut fuer Halbleiter- und Mikrosystemtechnik, TU Dresden E-mail: hoffmann at

plot(rnorm(100000),type="l") plots only about 7e4 lines while the same without type="l" works fine. Is this a feature or a bug or is this configurable?

i want to replace certain values of a matrix. i know how to replace them when the values are in a vector. i tried the same way for a matrix and got this answer: la[la==0]<-1 Error in [<-.data.frame(*tmp*, la == 0, value = 1) : matrix subscripts not allowed in replacement i found a way to do this with "for()", but i think this is the worst way to do it. So is there a

Hi! I am using the fft() function the base package to transform some 1d signal. If I use this standar fucntion I get a very huge first fourier coeficient. I think this dues to the handling of the borders of the signal. Usually in fft especially in image processing the signal is simulated to be continuous by adding the signal several times periodically. My question is, is there some function

Hi! I am using R 1.8.1 and the svm of the e1071 package for classification. The problem is that I have unbalanced classes e.g. the first one is much bigger than the second one and therfore the svm is biased to the first class. If I manually adjust the class size the bias disappears. The question is then how to include this unequal class distribution to the svm (e.g. via wheights or costs)?

Dear all, may be somebody have ideas to my following problem: I have to multiplicate each element of a vector with his position in the sorted vector. This isn't a problem ;-) But now i have a weighting vector with the weight of each observation, and my problem starts. A little example (due to my bad english) maybe helps to understand: x<-c(10,40,50,100) # income vector for instance

Dear R user, I'm relative new and need some help / advise from you. I have organised my data in several frames, mainly because the data came from different sources. One common variable in all data frames is the day post transplantation. I would like to combine the data frame to one big data frame which contains all the data, however no duplicate rows should occour (only one row for one
