Hi, you could use "scan" instead, it seems to work fine also when wrapped around "unz". Or, alternatively, you could use "unzip" instead of "unz". It works as expected, i.e. reads the last incomplete line and throws a warning about this. So it seems to me that "unz" creates a non-blocking connection, whereas "unzip" creates a

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.

Hi again, The unz connection is non-blocking by default. I checked do_unz which calls R_newunz which calls init_con and the only place in any of those functions that sets 'blocking' is init_con which sets it to FALSE: https://github.com/wch/r-source/blob/0c26529e807a9b1dd65f7324958c17bf72e1de1a/src/main/connections.c#L713 I'll open an issue on R-bugzilla and see if they're

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" >

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"))

Dear list, I'm seeing a strange interaction with readLines() and unz() when reading a file without an empty final line. The final line gets dropped silently: > cat("hello", file = "hello.txt") > zip("hello.zip", "hello.txt") adding: hello.txt (stored 0%) > readLines(unz("hello.zip", "hello.txt")) character(0) The

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

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

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:

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

Hello R-help! I just wanted to share a tip might help others of us stuck on R. The documentation for zip.file.extract is rather scant, and a few examples would. When using zip.file.extract, the first argument should be the full (or relative) path and the second the name of the zip file, it seems. While this is counterintuitive to me, that it should get the part from the first argument,

Dear alltogether, I want to use CGIwithR in conjunction with R2HTML. A small example called 'test.R': ##### #! /usr/bin/R invisible(capture.output(library(R2HTML))) HTML(summary(as.numeric(scanText(formData$numbers))), file=stdout()) ##### The script gets its input via 'CGIwithR.cgi' and contains the variable "numbers." The 'HTML' output (-> summary() in

I'm doing some work in C with the R_ExternalPointer interface, and having some seg fault problems. I expect the crash is my fault, bad pointer in my code causing a fault later etc, but I'm curious about the point of failure. R almost always falls over in a call to unzReadCurrentFile following a burst of disk activity. I'm definitely not doing anything that would call that

Hello I am trying to read a large number of WinZip files from inside R (v 1.7.1, options()$unzip = internal). I have unsuccessfully tried to unpack the files and write to an external directory so that I could read the text files using zip.unpack. Reading some of the archives suggests that this is for .ZIP format files only. I have also unsuccessfully tried to use gzfile to open a connection and

Can anyone point me in the right direction for decompressing text files that are compressed as tar.gz or zip files?

Hi, I'm trying to add a Windows NT/2000 OKI C5100 print driver to a Samba 2.2.3a server. I've been told that this driver does some server-side stuff, so I'll have to use 'adddriver' in rpcclient. I've read the manual page for rpcclient, and I printed out a 'Windows 2000 Printer Test Page' to get all the relevant information. This is probably just something

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
