similar to: zip.file.extract on Windows

I received several answer to my querry re reading zipped files, R.Gentleman, Liaw Andy, BD Ripley,J Holtman, A.Matt, and others, sorry if I missed your names. a- use pipe to run external unzip to a file and read from there b- use gzfile() to open directly a gzipped file c- use zip.file.extract() solution b works like a charm, unfortunately it open gzipped files and not zipped files, would it be

Hi Reading the help for ?unz I was wondering if I can read data into R from within an zipfile that is on some website, like maybe: dtaa = read.table(unz("http://www.ats.ucla.edu/stat/examples/alsm/alsm.zip","Ch01pr19.dat")) Thanks for letting me know if you came acros such a thing before. Toby

Dear List, Does somebody know how to get the filename lists in the ziped when "gzfile" or "unz" command is used ? Thanks for your help. Shawn Lee -- The information contained in this communication and any atta...{{dropped}}

Hi List I have a series of zip archives each containing several files. One of these files is called goCats.txt and I would like to read it into R from the archive. It's a simple tab delimited text file. pathToZip <- '/home/iain/Documents/Work/Results/bovineMacRNAData/deAnalysis/afInfection/commonNorm/twoHrs/af2hrs.zip' z <- unz(pathToZip, 'goCats.txt', 'r') zT

I get unexpected behavior from "readLines()" and "scan()" depending on how the file is opened with "gzfile" or "unz". More specifically: > file <- gzfile("file.gz") > readLines(file,1) [1] "a\tb\tc" > readLines(file,1) [1] "a\tb\tc" > close(file) It seems that the stream is rewound between calls to readLines.

I am having problems getting the unz() function to work as a connection to start reading a file... z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") readLines(z,2) yields the following problems: > z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") Error in unz("c:/temp/stoxx.zip",

Hi, I have downloaded a bunch of bz2 files. I wonder if R will be able to unzip them in a batch mode or even one at a time? I was looking at the unz function. But it didn't work well. Say I have a bz2 file in H:/Temp/65502805_532.pair.bz2. Anyone has any suggestion? thanks John > setwd("H:\\Temp\\") > getwd() [1] "H:/Temp" >

Hello everyone, Can anyone give me some hint/suggestion for unzipping a file in R? The help file for "zip.file.extract" function seems to be difficult to understand. For example, the name of my zip file is "refGene.txt.gz", which is located in "C:\Documents and Settings\Desktop\test1". I would like to unzip this file to the same directory. Here's

I would greatly appreciate some example of correct usage of function unz. I have to download and uncompress the following web compressef file: ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.homo_sapiens.zip I tried the following command that does not work: Targets.rec <- readLines(zz <- unz("ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.homo_sapiens.zip"))

Not sure this is a bug in R. Maybe its a bug in my understanding of unz(). The character 'b2' (hexadecimal) is in position 535 of line 1 of 'naughty.csv'. This character appears as superscript '2' and came to me in an EXCEL file that I converted to text in a comma separated ( *.csv ) format. The first line gets truncated by readLines after 534 characters using unz():

As part of my work, I am trying to append matrices onto data frames. Naively I assumed that when rbinding a data.frame and matrix, the matrix would be coerced and appended, keeping the names from the data frame. Clearly, I am not fully understanding the process by which rbind works. Example code: > A<-data.frame(1,1,1); names(A)=letters[1:3] ; B<-matrix(0,2,3) > rbind(A,B)

Hi Sorry, I am clearly missing something here. I want to read this file directly: ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.gallus_gallus. zip I tried using read.table(gzfile("ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5 .txt.gallus_gallus.zip")) But I got an error: Error in open.connection(file, "r") : cannot open the connection In addition:

I have a zip file. It is over 2Gb in size: -rw-r--r-- 1 sweh sweh 2383956582 Mar 13 13:44 test.zip The standard "unzip" program barfs: % unzip -l test.zip Archive: test.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment

Dear list, I needed to extract a zip-archive, and found zip.file.extract in utils. My only problem was the use of tempdir(), since I wanted to permanently extract the archive at a fixed location for later use. My own fix was simple, adding an extra parameter zipdir (without default), and within the function change tmpd <- tempdir() to tmpd = ifelse(missing(zipdir),tempdir(),zipdir) This

Hi, I downloaded a package with .gz extension, which presumably works for Unix, when I installed it directly on windows, it has the error msg: Error in gzfile(file, "r") : cannot open the connection In addition: Warning messages: 1: In unzip(zipname, exdir = dest) : error 1 in extracting from zip file 2: In gzfile(file, "r") : cannot open compressed file

Hi All, I've just upgraded our CRM and it has an Asterisk Integration Module that I would like to test out. The CRM is running on one of our hosted servers in the cloud. The Asterisk server is running in my office. I am running Asterisk 1.4.21.2~dfsg-1ubuntu3. Reading the page http://www.voip-info.org/tiki-index.php?page=Asterisk%20config%20manager.conf got me a little concerned

My apologies for asking what is doubtless a dumb question, but I have scant experience in R. It would be very convenient in doing lots of plots to be able to do them in a loop that stepped through a vector of variable names. For example one could say x<-("mydates") y<-c("foo1","foo2","foo3") #where "foon" were vectors

I had trouble with some tests for the survival suite last night that I cannot explain. Framework: Ubuntu Linux, R2.11. For testing survival I have a separate directory and Makefile. I pull everything into the local .RData, no packages, library, or namespace. (It's easier to add test modifications to a routine in a chain of calls). A test of survreg + psline would fail because

Hi all, In the last few days, some change introduced an internal compiler error. On my G4 (PPC), I'm getting this: $ cat testcase.i struct A {}; struct B { struct A c[0]; }; extern const struct B *pB; void bork(void) { const struct A *pA = pB->c; } $ /Users/wendling/llvm/llvm-gcc-4.2.obj/./gcc/xgcc -B/Users/wendling/ llvm/llvm-gcc-4.2.obj/./gcc/ -B/Users/wendling/llvm/llvm-

Hello, is there a way to pass a connection to a file in a zipped archive as argument (instead of a file name of unzipped file) to shell command "cut". In general, is it possible to pipe output of a R function to a shell command? How? I want to do something like: z = unz("zipArchive.zip", "fileASCII.ASC") # open connection open(z) # cut lines of the ASCII file in
