Hi, I was wondering if anyone knows of a package that contains the ability for peak/valley detection. Here is an example of what I'm looking for, only problem is that it's written in Matlab. http://www.billauer.co.il/peakdet.html Thanks for any help in advance. -Joe

The difference in the return value of close(pipeConnectionObject) seems to depend on whether the pipe connection was opened via the pipe() or open() functions (close() returns NULL) > con <- pipe("ls") > open(con, "r") > readLines(con, n=1) [1] "1032.R" > print(close(con)) NULL > con <- pipe("ls", "r")

Is there a way to get the status code of a pipe() command? The documentation suggests that it might be returned by close, however this does not seem to be the case. con <- pipe("cat /etc/passwd", "r") stream <- readLines(con, n = 10) err <- close(con) print(err)

I have very large csv files (up to 1GB each of ASCII text). I'd like to be able to read them directly in to R. The problem I am having is with the variable length of the data in each record. Here's a (simplified) example: $ cat foo.csv Name,Start Month,Data Foo,10,-0.5615,2.3065,0.1589,-0.3649,1.5955

Hi,all I have a problem running R.matlab package (under 2.10.1 version). I can set up the matlab server under local machine(run the MatlabServer.m), " And I can use setVariable and evaluate matlab functions in R. But when I ask Matlab to send the value back to R using getVariable function it always returns an error: " ??? Error: A MATLAB string constant is not

Dear All, Currently, I am translating Matlab code to R. I met difficulties to translate such Matlab codes into R: fprintf(fid,(' SPLITTING RESULTS ')); fprintf(fid,(' \n')); fprintf(fid,' Data base to analyze is a matrix %4i x %2i ',[n m]); fprintf(fid,' \n'); fprintf(fid,' h is %2i',h); fprintf(fid,' \n'); fprintf(fid,' group=0

Hello all, I'm a new user of R, experienced with Octave/MATLAB and therefore struggling a bit with the new syntax. One of the easy things in Octave or MATLAB is to plot multiple lines or sets of points by using a matrix where either the columns or the rows contain the y-values to be plotted. Both packages automatically give each line/points their own unique colour, character etc. I'm

Hi I am using Ubuntu 8.04 64 bit, R as below, Matlab 7.6.0. I would like to transfer mat files back and forward between R and Matlab. Whilst I have used Matlab for years its been a long time since I have used R (hence question may be a bit simple) Running code A <- c(1:10) dim(A) <- c(2,5) library(R.matlab) writeMat('A.mat', A=A) Does not appear to generate any mat file

Hi All, I have two questions on R. Could you please explain them to me? Thank you! 1) When call a function, R typically copys the values to formal arguments (call by value). This is very cost, if I would like to pass a huge data set to a function. Is there any situations that R doesn't copy the data, besides pass data in an environment object. 2) Does R pre-compile the object function to

I have been working with R extensively for several months. I switched from SAS and Matlab to R. My question is Can anyone explain the benefits and detractions of the 'Date' package verses the 'date' package and verses 'POSIX' dates. I have noticed several other packages use one or the other. Rmetrics seems to standardize on POSIX. I can only see differences in

Hey, I was wondering if there existed a R function similar to 'fsolve' or 'fzero' Matlab functions? Thanks! Francois Aucoin [[alternative HTML version deleted]]

Hi, I am seeing this on Linux as well as MacOS: Opening any output pipe from R 4.4.0 to TTY programs like "less"/"more" hangs, SIGINT-proof: > $ R/4.4.0/bin/Rscript -e 'pipe("less", "w")' > $ R/4.4.0/bin/Rscript -e 'cat("test", file="|less") > $ R/4.4.0/bin/Rscript -e 'cat("test",

Hi all, Are there any plans to add more functionality to command-line editing and history editing on the command line? In MATLAB (I know, comparisons are odious ...), you can type "p" and up-arrow on the command line and scroll through the recently entered commands beginning with "p". This is a very useful feature and something that I believe is not replicated in R. Please
