Dear all, I am stuck the reading of a file which has 100s of rows and variable column counts. The tab-limited data file looks something like: Some_Text 1 3 123 1534 -119 1010 178 Some_Taxt 1 3 133 1434 -219 1010 178 Some_Tsxt 1 3 244 1334 -319 1010 178 Some_Tfxt 1 3 153 1234 -419 1010 178 Some_Trxt 1

Dear all, I'm stuck with a problem using plyr to process a rather large junk of data. What I'm trying to do is applying a moving average to all the subparts of the dataframe (the example data can be found here https://dl.dropboxusercontent.com/u/2414056/testData.Rdata). require(plyr) load("testData.Rdata") applyfilter<-function(x){ return(filter(x,rep(1/5, times=5))) }

Dear all, I am facing a challenge when applying the outer product with a matrix by rows. What I have is a rather big matrix, which I would like to convert into a different matrix by doing something like outer(matrix_row, vector, function(x,y) x[1]+5*x[4]/y) In order to get there, I tried to get the matrix into a list using the mefa package, as subsetting the original data appears too

Dear all, I just found that some of the packages are not able to load any more, after I installed R2.0.1 in my Mac, it even affects my old R1.8 installs. It gives me errors when I load packages that contains "myEnv" settings. such as: RMySQL, DBI, Rggobi, etc. But others that does not require "myENV" is all right, like tcltk that only calls the c functions. The errors

I am trying to create a routine that would take a time series and generate monthly 25%tile and 75%tile limits based on 12 calendar months. I have succeeded to create a do loop to do this, but can't figure out how to initiate the receiving datafile (in this case "limit.list") without sticking an initial set of zeroes in. I'd like to be able to insert a new column

I have data of the form tC <- textConnection(" Subject Date parameter1 bob 3/2/99 10 bob 4/2/99 10 bob 5/5/99 10 bob 6/27/99 NA bob 8/35/01 10 bob 3/2/02 10 steve 1/2/99 4 steve 2/2/00 7 steve 3/2/01 10 steve 4/2/02 NA steve 5/2/03 16 kevin 6/5/04 24 ") data <- read.table(header=TRUE, tC) close.connection(tC) rm(tC) I am trying to calculate rate of change of parameter1 in

Hi folks, I'm prepared building my own datafiles, simple file at start, for testing wondering how to process? Which software will be used, MySQL/MS-SQL/MS-Excel/Open Office-Calc etc? On searching I found r-cran-rmysql on Ubuntu repo. Further searching I found; RMySQL: R interface to the MySQL database http://cran.r-project.org/web/packages/RMySQL/index.html Whether install the above

Hi all, I am having a small problem with a catch-all user I have setup in my Postfix/Dovecot setup. I am not 100% sure this is Dovecot related, but, logic tells me it is. I have a virtual user called @reinhold.dk setup to redirect to my main account, peter at reinhold.dk. If I send a spam mail (GTUBE) to peter at reinhold.dk, the mail is marked with Amavis x-headers as it should be. If I

Hi Ansley It looks good to me but I did not run the analysis as I am too lazy to install "indicspecies". The inclusion of the raw data is a great help.

I have no idea to be honest. I have never used the package, I simply did a search for it.

With the same configuration an ISOLINUX CD which boots a FreeDOS Floppy image via MEMDISK Syslinux-3.73 crashes in VMWare and also on several newer boxes just after the kernel loading with "invalid OPCODE ...". Same CD with Syslinux-3.72 is working fine. Build environment for 3.72 was gcc-4.3.2 for 3.73 gcc-4.3.3 - any idea what can cause the troubles? --

Dear All, I would like to use the simprof function (clustsig package) but the available distances do not include Jaccard distance, which is the most appropriate for pres/abs community data. Here is the core of the function: > simprof function (data, num.expected = 1000, num.simulated = 999, method.cluster = "average", method.distance = "euclidean", method.transform =

Well, here is one way but it seems a bit clumsy. In words, I created a new data.frame with "250" in the Chloride vector and "SMCL" in the Detections vector and supplessed one legend. Warning: For my convenience I am using different data.frame names . library(ggplot2) MyData <-read.csv("http://doylesdartden.com/Stats/TimeSeriesExample.csv", sep=",")

Hi, I am trying to use piecewise linear regression to approximate a nonlinear function. Actually, I don't know how many linear functions I need, therefore, I want build an array of regression models to automate the approximation job. Could you please give me any clue?

Dear all, Let say I have following data: RawData <- matrix(1:101, nr = 1); colnames(RawData) <- c("ASD", as.character(as.yearmon(seq(as.Date("2012-03-01"), length.out = 100, by = "1 month")))); rownames(RawData) <- "XYZ" CutOffDate <- as.Date("2012-09-01") NewDateSeries <- as.character(as.yearmon(seq(CutOffDate, to =

Hi Dennis, SOLVED!!! My thanks to both you, John, and others who chimed in. Took a little more digging before finally working, but it is working! Here's a little more of what I did and the ultimate resolutions: I installed the reshape2 library from CRAN. Executed > (.packages()) [1] "reshape2" "stats" "graphics" "grDevices"
