Umm sorry to bother everyone again but I'm having trouble with my if statement. I come from a perl background so that's probably my problem! :) So here is my code: if (any(lgAB>4) | any(lgAB<-4)){ freq_AB<-hist(lgAB, type="o", plot=F) else freq_AB<-hist(lgAB, breaks=br,type ="o", plot=F) } And I get > source("E:/R/GMDA-1.1.R") Error in

Hello, I'm doing some scripting and I've noticed that R doesn't seem to have an if (cond){ do }ifelse (cond) { do } else { do } type block. Is this correct or am I missing something. THX Paul -- Research Technician Mass Spectrometry o The / o Scripps \ o Research / o Institute

Hello, Sorry to all for the lack of communication, and thanks to those with the suggestions. So I have two matrixes which are different sizes, same column number but different row number. What I would like to do is to compare A to B. In the 6 and 9th column there are ref numbers (molecular masses to be exact). I would like to check A and B by these columns. If I find that the number in A[9,x]

Dear All, I have a matrix with data that is not organised. I would like to go through this and extract it. Each feature has 2 vectors which express the data. I also have an index of the places where the data should be cut. eg. >class(cc) "matrix" >cc [,1] [,2] [1,] 1 26 [2,] 2 27 [3,] 3 28 [4,] 4 29 [5,] 5 30 [6,] 6 31 [7,] 7 32

Hello, I apologise if someone has already answered this but I searched and googled but didn't find anything. I have a matrix which gives me the similarity of each item to each other. I would like to turn this matrix into something like what they have in the graph package with the nodes and edges. http://cran.r-project.org/doc/packages/graph.pdf . However I cannot find a method to

Hello all and thank you, I will try to make this as clear as I can. I have a matrix, at the top of the matrix are 4 time points, the first col describes the sample, then under each time point I have the intensity values of that sample. So : Samples 0 10 30 120 <- time A 200 300 400 1000 <- data B 100 400 200 100 C 500 400 200 1000 ^ | samples I would like to plot these however, all I

Dear all, Thank you for any help. I have a data.frame and would like to plot it in 3D.

Hello all, I know this is a pretty easy question but I can't find it in S poetry or R help. How can I make a negative number positive. Such as -5 to be +5 I tried +(-5), but that didn't work. So no, I don't mean taking a -5^2 just to get a positive number. This is in a function so it's not just -5 it's x. :) Thanks, Paul -- Research Technician Mass Spectrometry o The

Thanks again everyone, I have a problem trying to install RMySQL on Suse 10.0. I have used both the install.packages() and the 'R CMD INSTALL RMySQL..." neither worked. I get the error message telling me that it cannot find mysql. So I have set the flags using export PKG_CPPFLAGS="-I</usr/bin/>" export PKG_LIBS="-L</usr/lib/mysql>" After that I run R

Hello all, I'm looking for a way to be able to read a text file into R. It's a csv file but when I do "txt <-read.table("F00.csv", header=T, sep=",")" It doesn't read the file properly, and I only get 2 columns. If I open it up in OOc or Excel it open right with 7 columns. What I would really like to do is read the file as text and then split it and

Hello, This should be a fairly simple question. I have 2 matrix's and I want to get the difference between them and then remove the difference from one of them. So A vs B, anything I see in B I want to remove from A, and then print out the final matrix. I have some code here but at the moment I'm getting stuck on the creating a matrix, cbind problems. clean <- function (A, B,

So thanks for the help, I have a matrix (AB) which in the first column has my bin numbers so -4 - +4 in 0.1 bin units. Then I have in the second column the frequency from some data. I have plotted them and they look roughly Gaussian. So I want to fit them/ find/optimize "mu", "sigma", and "A". So I call the nls function : nls_AB <- nls(x ~ (A/sig*sqrt(2*pi))*

Dear all, Just a quick one, hopefully. I have a histogram made from the method 'hist()'. How do I get labels on the bars? Such that the bars will have the x axis on the bar, not the frequency of the point but the number of the point itself. To make a quick summary, I want the the numbers from 'losses' (below) to be on the bar's. Thanks, Paul

Dear helpers, I have multiple vignette files for a package, and I would like to have the "right" order of these files when displayed online. For instance, see below: https://cran.r-project.org/web/packages/bst/index.html The order of vignette links on CRAN is different from what I hoped for: > vignette(package="bst") Vignettes in package 'bst': pros

I think the online order of vignette files are not based on vignette title or filename alphabetically. I am just curious: by what order these vignette files were displayed online so I can make changes accordingly?

I seem to have gotten past one hurdle and on to the next. It seems that the problem that I was having relates to poorly documented changes in the config files in the HOWTO.

I have a vector with about 100.000 values representing a quite regular function (sinusoid like). I would like to find all local maxima of this function (should be about 4000).
