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

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, 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 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

Hello, I have another (possibly easy) question: How to specify the size of a plot? When I draw a plot, I can freely change the size of the window, which is nice for single plots to find the best height/width ratio, but as I need a lot of plots in my work, I want to look them all the same, so I need to specify the size in advance. Thanks for help, Christoph

Hi, I am a new R user. I am using it develop regression models with categorical variables. Is there a way to force some regression coefficients to be 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

Hello everybody My collegue and I noticed a strange behaviour of R on different platforms. It's a simple computation, but results are rather different. On Windows XP: > floor(log(8,2)) [1] 3 which is what one should expect. Here's instead the result with Mac OS X (same version, 2.5.0 (2007-04-23)) > floor(log(8,2)) [1] 2 Is it a "bug" in R or in the operating

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 Mike Find enclosed the patch with the fastart implementation for vorbis (for the moment). Now is based on size in bytes and the buffers are sent all together with pre_data. Hope you like it.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, find a patch which is an update to a patch sent months ago. Before it was in net/sock.c, now I moved it to format.c, so net CVS module is not affected. It polls the socket before trying to send() any byte to check if the TCP buffers are full due to network congestion. See below the warning messages of "normal" (at least in
