I'm comparing R-1.3.0 on Solaris 2.6 to R-1.3.1 on WindowsNT. The following 5-line script returns TRUE on Unix but FALSE on NT: fnam <- tempfile() file.create(fnam) txt <- paste("file.exists(\"", fnam, "\")", sep="") expr <- parse(text=txt) eval(expr) The issue seems to be that backslashes get lost in the parsing. A workaround is to change

Working on Windows I have had to deal with CSV files that, unfortunately, contain embedded Control-Zs, i.e. ASCII character 26 in decimal, and the readLines() function in R on Windows (2.15.2 and 3.0.0) appears to truncate at the control-Z. There is no problem at all on Ubuntu Linux with R 3.0.0. Am I mistaken or is this genuine? # Create a small file with embedded Control-Z h3 <-

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

Hi, I have a very large data file(GB) from which I only want to extract one column to draw histogram. This would be done several times, so I would like to ask if there is anyway to plot this using R from the linux command line, something look like this cut -f1 xxx.txt |RplotHist .... Thanks and hope to hear from you. Best regards, Hang [[alternative HTML version deleted]]

Dear all, I need to do the same procedure on several files. But I don't know how to refer to the file name. Here is an example of what I am trying to do. List of files: file1(A,B,C, D1...Dn), file2(A,B,C,E1,...,En), file3(A,B,C,F1,...,Fn) Procedure I want to apply on each file: dft <- melt(df,id=c('A','B','C')) dft$X <- substr(dft$variable,1,3) dft$Y <-

Question: would it be better if the contents list of the unzip() function returned the filenames as character rather than factor since they are probably unique strings? > tmp <- unzip(fnam, list=TRUE) > str(tmp) 'data.frame': 31 obs. of 3 variables: $ Name : Factor w/ 31 levels "fred1.csv",..: 1 2 3 4 5 6 7 8 9 10 ... $ Length: num 424486 2664277 219798 442383

Hi folks, I've been using 'PBSmapping' to make a map of Europe with some labels. I've been using the 'worldLL' PolyData, as my computer is too slow to make my own from the GSHHS files. The only problem is this PolyData does not seem to include Ireland. I have no idea why this should be so, other European islands such as Sardinia etc. are included.

I have a pdf file that I would like to parse into R: http://www.williams.edu/Registrar/geninfo/faculty.pdf For now, I open the file in Acrobat by hand, then save it "as text" and then use readLines(). That works fine but a) I am concerned that some information may be lost and b) I may be doing this a lot, so I would rather have R grab the information from the pdf file directly. So: is

Dear R users, I have numerous data sets (csv files) saved in the folder which has the same name as individual data. (i.e data x1 saved in x1 folder, data x2 in x2 folder etc) I would like to read in the desired data set name using 'scan' function and assign this inputted value to an object so that it can be used in the 'read.csv' function. For example, x <- scan() 1: 0708

Hello, I frequently have to export a large quantity of data from some source (for example, a database, or a hand-written perl script) and then read it into R. This occasionally takes a lot of time; I'm usually using read.table("filename",comment.char="",quote="") to read the data once it is written to disk. However, I *know* that the program that generates

Some of the debug messages that rsync outputs (when verbose >= 2) can occur on both sides of the connection. This makes it hard to know which program is saying what. Some debug messages deal with this by outputting a "[PID]" string at the start of the message. Unfortunately, the startup message that tells us which pid is which is only output when verbose >= 3, so there's a

I'm getting a SEGV on a FreeBSD 4.8-STABLE box. The client is Solaris 9/SPARC. Both boxes run 2.6.2.

We use rsync in a Linux installation script. First, the root filesystem of another machine on the network is cloned with "rsync -axzH", and then a few files are updated to give the clone its own identity. This works fine, but last week, the Postfix mailer daemon on a new machine refused to start because some lock files had a link count of 2. It turned out that rsync had created two

As those of you who watch CVS will be aware Wayne has been making progress in reducing memory requirements of rsync. Much of what he has done has been the product of discussions between he and myself that started a month ago with John Van Essen. Most recently Wayne has changed how the file_struct and its associated data are allocated, eliminating the string areas. Most of these changes have been
