I'm working with a very large matrix ( 22k rows x 2k cols) of RNA expression data with R v.2.5.0 on a RedHat Enterprise machine, x86_64 architecture. The relevant code is below, but I call a function that takes a cluster of this data ( a list structure that contains a $rows elt which lists the rows (genes ) in the cluster by ID, but not the actual data itself ). The function creates two

Hello, I used read.xlsx to read in Excel files but for large files it turned out to be not very efficient. For that reason I use a programme which writes each sheet in an Excel file into tab-delim txt files. After that I tried using read.table and read.delim to read in those txt files. Unfortunately, the results are not as expected. To show you what I mean I created a tiny Excel sheet with some

Hi, Im reading in a .txt file into R that consists of 5 columns, however, when imported into R, it reads all the data into just one column. Is there a way of telling R to create a dataframe with 5 columns rather than putting all the data into one column? Thanks -- Shane [[alternative HTML version deleted]]

In R 1.9.0, make.names will accept "_" as a valid character for a syntactically valid name. I would appreciate to have an option in ``read.delim'' (etc.) that would change "_" in headers of input files to "." for compatibility with code and data written for R 1.8.1 and before. Wolfram Fischer

Hi, It would be great if someone would add write.delim() as an adjunct to write.table(), just as with write.csv(). I store a lot of data in tab-delimited files and can read it in easily with: read.delim("text.txt", as.is=TRUE) and would love to be able to write it out as easily when I create these files. The obvious setting needed for write.delim() is sep = "\t", but in

Hi, I am trying to read a tab-delimited file into R (Ver. 2.8). The machine I am using is 64bit Linux with 16 GB. The file is basically a matrix(~600x700000) and as large as 3GB. The read.delim() ran extremely slow (hours) even with a subset of the file (31 MB with 6x700000) I monitored the memory usage, and found it constantly only took less than 1% of 16GB memory. Does read.delim()

Hi I have a huge data-set with one column being of type date. Of course I can import the data using this column as "factor" and then convert it later to dates, using: sws.bezuege$FaktDat <- dates(as.character(sws.bezuege$FaktDat), format = c(dates = "d.m.y")) But the conversion requires a huge amount of memory (and time), therefore I would

Hi R folks, Can anyone tell me how to read in a pipe ("|") delimited text file? I've tried the following: read.delim("c:/junk/junk.txt",sep="|", skip=7, check.names=FALSE,quote = "", header=F) The file looks something like the following: RD|I|04|013|9997|68103|5|7|017|830|20000221|00:00|12.6||6|||||||||||||

Dear friends, I stumbled into beheaviour of read.delim which I would consider a bug or at least an inconsistency that should be improved upon. Recently we had to work with data that used "", two double quotes, as symbol to start and end character input. Essentially the data looked like this data.csv ======== V1, V2, V3 ""data"", 3, """" The

I am reading in a very large file with names in it and R is truncating the number of rows it reads in. The separator in this file is a pipe '|' and so I use dat <- read.delim('pathToMyFile', header= TRUE, sep='|') It turns out that it is reading up to row 61145 and stopping and I think I see why, but am not sure of the best solution to this problem. I see the name of

Is there a better way to do the following? I have data in a number of tab delimited files. I am using read.delim() to read them, in a loop. I am invoking my code on Linux Fedora 20, from the BASH command line, using Rscript. The code I'm using looks like: arguments <- commandArgs(trailingOnly=TRUE); # initialize the capped_data data.frame capped_data <- data.frame(lpar="NULL",

Hello All, I've been using R for two years now and I am happy to say this is the first time I could not find the answer to my problem in the R-help archives. Here is the pending problem: I want to be able to insert delimiters, say commas, into a string of characters at uneven intervals such that: foo<-c("haveaniceday")#my string of character bar<-c(4,1,4,3) # my vector of

Hi, I have a tab seperated file with 206 rows and 30 columns. I read in the file into R using read.table() function. I checked the dim() of the data frame created in R, it had only 103 rows (exactly half), 30 columns. Then I tried reading in the file using read.delim() function and this time the dim() showed to be 206 rows, 30 columns as expected. Reading the read.table() R-help documentation, I

Hi all, I am running 64-bit R 2.15.0 on windows 7. I am trying to use read.delim to read from a file that has 2-byte unicode (CJK) characters.

I have written a function which reads data from files using read.delim (). The names of these files are complicated and are built using arguments to the wrapper function. Since the files in question may or may not exist, I thought to enclose the read.delim() call in a try(): file <- <complicated expression> temp <- try(read.delim(file)) if(inherits(temp,"try-error")) {

I am trying to read a tab-delimited 1.25 GB file of 4,115,119 records each with 52 fields. I am using R 2.11.0 on a 64-bit Windows 7 machine with 8 GB memory. I have tried the two following statements with the same results: d <- read.delim(filename, as.is=TRUE) d <- read.delim(filename, as.is=TRUE, nrows=4200000) I have tried starting R with this parameter but that changed

Dear list, I hope this is the right place to post a feature request. If there's exists a more formal channel (e.g. as for bug reports), I'd appreciate a pointer. I work a lot with named nested lists with arbitrary degrees of "nestedness". In order to retrieve the names and/or values of "bottom layer/bottom tier", I love the functionality of 'unlist()', or
