...zero for some of the values in a categorical variable (with 12 factor levels)? I am recoding the values to the default value (1st in the order of dummy's). But I am not sure if this is the correct approach if I want to force coefficients to be specific values. Thanks for your help. Regards, Danda [[alternative HTML version deleted]]

Dear All, I would like to run R on my computer (with win xp on it) at work bu the proxy restrictions of the university don't let me download the packages or to connect to a cran mirror, I usually get this message: > chooseCRANmirror() Warning message: In open.connection(con, "r") : unable to connect to 'cran.r-project.org' on port 80. Do you know if there is a way to

Dear All, I hope you don't mind helping me with this small issue. I haven't been using R in years and I'm trying to fill in a matrix with the output of a function (I'm probably using the Matlab logic here and it's not working). Here is my code: for (i in 1:length(input)){ out[i,1:3] <- MyFunction(input[i,1],input[i,2], input[i,3]) out[i,4:6] <-

Hallo, I have a vector of several iterations and I have to remove /filter out all the values < than 10, how can I do this?

Hallo, How can I have the control of the width of each bin in the histogram? I would like to plot my data modifying the number and the width of the bins. Is there a good pdf or manual where i can learn to use the plot/hist in R very well? I find the help not always clear Thanks a lot Ale -- View this message in context: http://www.nabble.com/Histogram-tp24325261p24325261.html Sent from the R

Hallo, I have an other problem, I have this vector signData with an alternation of 1 and -1 that corrispond to the duration of two different percepts. I extracted the durations like this: signData<- scan("dataTR10.txt") dur<-rle(signData)$length Now I would like to extract only the positive duration, e.g. signData <- c(1,1,1,1,-1,-1,-1,1,1,-1,-1) posduration <- c(4,2) I

Hi, I need your help!! I imported a big coloumn vector from a txt file but it results as mode :"list" I want to change it in numeric otherwise I can't do my analysis. This is what i get: mode (data) <- "double" Error in eval(expr, envir, enclos) : (list) object cannot be coerced to type 'double' > Thanks a lot!!! Alessandra -- View this message in

Hi, I need to fit my data with beta-prim distribution. I found the function in the package VGAM: betaprime and betaff. I don't know how can I make it work. I know that i need to calculate the parameters that describe this function on my distribution. But for exemple I don't understand the "link function. And then How can I plot my data fitted? Can you help me out with this? Thanks

Hi, I need your help. I have a vector of numbers reflecting the switch in the perception of a figure. For a certain period I have positive numbers (which reflect the perception A) then the perception changes and I have negative numbers (perception B), and so on for 40000 iterations. I need to take the rate of this switch for my analysis. Namely, I need a new vector with numbers which reflect how

Hallo, I need your help. I fitted my distribution of data with beta-prime, I need now to plot the Cumulative distribution. For other distribution like Gamma is easy: x <- seq (0, 100, 0.5) plot(x,pgamma(x, shape, scale), type= "l", col="red") but what about beta-prime? In R it exists only pbeta which is intended only for the beta distribution (not beta-prime) This is

Hi, Is there a way to recursively change the variables imported with read.table(..) - and then attached with attach(..) - from as.factor to as.integer? I have about 9 variables that are now recognized as factors but I need to do statistics on them so I need to change them in as.integer. It works, but I wonder if there is a way to to this for all the variables in one go. Thanks a lot for your

Hi All, Here is the problem: I'm trying to generate a number of Fourier Descriptors figures for an experiment. All I need is that they are created within a loop and saved with sequential names (e.g., s1_1.png, s1_2.png etc..) in my directory. I created a nested loop with a counter for the different amplitudes for the actual shapes and a counter for the file names. This script: *count
