Hi all, I have a question concerning xyplot. My data is a data.frame looking like that: In the first column I have numbers from 0 to 23 (hours of a day), the second column contains the name of a weekday (Day as factor) and the third column contains the number I am interested in. So as an example, the first five rows look like that: Hour Day Freq 1 0 Mo 23 2 1 Mo

Hi there, I have a question, which I thought is very easy to solve, but somehow I can't find a solution. Probably someone could help me quickly? Here it is: I have two matrices: a [,1] [,2] [,3] [1,] 1 4 9 [2,] 2 6 10 [3,] 3 6 11 [4,] 4 8 12 b [,1] [,2] [1,] 1 4 [2,] 2 5 [3,] 3 6 Now I want to find

Hi there, I am wondering if it is possible to do an xyplot with two y-axes. I'd like to print two parameters in a time series but they both have different scales. Which parameter in xyplot can I add to achieve this result? Thanks a lot for any help. Antje [[alternative HTML version deleted]]

Hi there, I was wondering if anybody can explain to me why the boxplot ends up with different results in the following case: I have some integer data as a vector and I compare the stats of boxplot with the same data divided by a factor. I've attached a csv file with both data present (d1, d2). The factor is 34.16667. If I run the boxplot function on d1 I get the following stats:

Hi all, I've got the following problem. I have a vector containing file names. I want to read these files as csv and calculate the density-function for each file (has just one column with data). Then, I'd like to plot all density functions into one window. I did the following to calculate the density data: s <- sapply(filelist, function(x) { if(file.exists(x)) { file <-

Hello, I guess the solution is rather simple but whatever I tried, I don't manage to get the result as I want to have it: I have several vectors of equal length in a list and I'd like to combine all first elements to a single string, all second elements to a single string, ..., all n-th elements to a single string. # Example code (how it should look like): t1 <- c(1,2,3) t2 <-

Hello, I'm not sure if I'm in the right place with my question... I'm running R on Windows and wrote a function and saved it as .R file. It looks like this: bmi <- function(weight, height) { bmi <- weight / height^2 bmi } If I want to use this function, I have to mark everything and then press Ctrl-R. But then everything single line is executed on the command line,

Dear group, First I provide you with an example, I found in the newsgroup. Then I'd like to explain my problem to you by means of the output. enviro <- data.frame(Year = rep(2001:2002, each = 365), Day = rep(1:365, 2), Precip = pmax(0, rnorm(365 * 2)), Temp = 2 + 0.2 * rnorm(365 * 2)) xyplot(Precip + Temp ~ Day | Year,

Hi, I think this is probably (& hopefully) very easy but I the ideas I have tried don't work. Simply, I have 2 very large lists in my workspace which take an awfully long time to make, each containing the information from 12500+ lmer models. I would like to now save these lists as files (txt, csv... whatever suits best) on to my computer/usb. Then I would like to be able to reload them in

Hi Roscoe, I couldn't make it though that excel worksheet without my eyes glazing over... but do you want something like data(mtcars) tab <- xtabs(~cyl + gear, data=mtcars) tab/sum(tab) ?

Dear all, I am really new to R, and I have problem here. I searched around, but did not get a solution. I have a numetrix matrix (20 by 25) saved in .csv. I read it as >sx<-read.csv("sx.csv",header=F) Then I try to convert it to numeric using >sx<-as.numeric(sx) Error: (list) object cannot be coerced to type 'double' The class of sx is "data.frame". I

Hello, I'd like to test a significance of two variables in their correlation using rcorr, which gave me an error of format incompatibility. Below are the lines that I typed in the R window and let me know if anyone knows how to resolve this. Var=read.csv("03apr10ab_corr_matrix_in_overlaps.csv",header=F) colnames(Var)=c("D Prime","T statistics") D Prime

Hello, I have another stupid question. I hope you can give me a hint how to solve this: I have a list and one element is again a list containing matrices, all of the same dimensions. Now, I'd like to set the dimnames for all matrices: example code: m1 <- matrix(1:25, nrow=5) m2 <- matrix(26:50, nrow=5) # ... there can be much more than two matrices l <- list() l[[1]] <-

Hello, I'm looking for a solution for the following problem: 1) I have a folder with several csv files; each contains a set of measurement values 2) The measurements of each file belong to a position in a two dimensional matrix (lets say "B02.csv" belongs to position 2,2 3) The size of the matrix is fix 4) I cannot assure to have a csv file for each position 5) Each position

Hi, I need to save output of summary() procedure to a csv file. It's all OK when it's applied to a 'factor' class variable, but when I try to save a 'integer' class summary to csv it gives me : > summary(rnorm(100, 10)) -> object > write.csv2(object, file='name.csv') Error in do.call("expand.grid", c(dimnames(x), stringsAsFactors =

Hello, Could anybody offer any advice about implementing a Kohonen self organizing map for categorical data? Specifically I am wondering if there are any pre-existent packages that can deal with categorical data and/or how one would compare the input vector of categoricals with the self organizing map nodes.
