Hi All, My R code takes very long time to finish the processing. I want to see at what stage the script is running. So I wrote some output messages using cat. But instead of displaying the cat messages at different stages they are buffered and displayed in the end when entire processing is done. Can you please suggest how to stop this buffering or some alternative way to display messages Thank

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()

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

I have a very large tab delimited file (~ 1.97 GB) that I need to read in to R. The data contain 10 columns and there are millions of rows. I need all rows of the data, but I only need the first column in the data. I was looking at the ?read.delim and am trying to see if it is possible to tell this function only to read in the first column and skip the others. The help file says the number of

I am trying to read in a pipe delimited file that has rows with varying number of columns, here is my sample data: A|B|C|D A|B|C|D|E|F A|B|C|D|E A|B|C|D|E|F|G|H|I A|B|C|D A|B|C|D|E|F|G|H|I|J You can see line 6 has 10 columns. Yet, I can't explain why R does like so: > test <- read.delim("mypaths4.txt", sep="|", quote=NULL, header=F,

Hi, I have 35 data files for reading. I would like get a program for performing reading of 35 files at once. All are of the type: Dados1.raw, Dados2.raw and so on. If the files have the same number of columns, I can read with the following commands: rm(list=ls()) filenames = list.files(path="~/Silvano/Arq", pattern="Dados+.*raw") names = substr(filenames, 1, 7) for(i in

Hello, I would like to read sets of files within a folder, perhaps using recursive methods. Right now, I rename the files before import. It would be even better to do this without renaming files, without providing explicit filenames, perhaps by importing files based on chronology, and translating each filename into a header? Please excuse my ignorance, and help cure my clunky programming

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",

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

Full_Name: Liam Gretton Version: 2.9.2 OS: openSUSE 11.1 (x86_64) Submission from: (NULL) (143.210.13.77) Reading a large number of rows of delimited data via the clipboard results in a segfault or double free error. I've tested copying from various applications, but gedit will do. This problem exists in the openSUSE-supplied 2.8.1, I've just built 2.9.2 to see if it's still there,

Dear R people, I have a very big tab-delim txt file with header and I only want to import several columns into R. I checked the options for "read.table" and only found "nrows" which lets you specify the maximum number of rows to read in. Although I can use some text editors (e.g., wordpad) to edit the txt file first before running R, I feel it?s not very convenient. The

Hi, We are considering organizing some of our ascii files with multiple "column names" like so: a.long.but.complete.name a.different.complex.name short.name.1 short.name.2 1 7 2 8 3 9 [more data] The basic idea is that we want to keep, in one location, both a long descriptive name of each variable (in row 1) and a short convenient name (in row 2). I could imagine keeping other

Hi, when I have made a decision tree with rpart, is it possible to "apply" this tree to a new set of data in order to find out the distribution of observations? Ideally I would like to plot my original tree, with the counts (at each node) of the new data. Reagards, Jay
