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. The same is true if I replace readLines with scan....

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", "...

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

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....

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" > fn<-list.fi...

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 5...

Hi! I'm trying to read individual files from a ZIP archive, using the unz() function. Some of the files contain non-ASCII characters and I'd like to avoid unpacking them in a temporary directory. My problem is that unz() seems to ignore the encoding="latin1" option I need to read the non-ASCII characters properly. I can't find a clear indication in t...

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}}

Hello all, I've got Unz (FM Towns emulator) running under wine but its not capable of reading the original FM Towns CDROM images on my Mac. I have it working under Windows XP using Daemon Tools to mount the ISO but under OSX it does not work. I have the ISO mounted under finder and have pointed my wine configuration to t...

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

...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 <- read.table(z, 'goCats.txt', header=T, sep='\t') Error in read.table(z, "goCats.txt", header = T, sep = "\t") :   seek not enabled for this connection The same error arises with readLines. Can anyone advi...

...addition: Warning message: In open.connection(file, "r") : cannot open compressed file 'ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.gallus_gallus .zip', probable reason 'No such file or directory' With all the different ways of opening connections (url(), unz(), gzfile(), gzcon() etc) I am just getting a bit lost. The above zip archive contains a single tab-delimited file, but one which I need to skip the first 5 lines. Any help appreciated! Thanks Mick

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 zipped archive at...

...unterintuitive to me, that it should get the part from the first argument, and apply that path to the second, it seems to how this works. This seems to me to be the wrong approach, since it won't handle folders inside the zipfile correctly. Am I missing something? Should I just use "unz" instead? Thanks, Gregg L.

...gical reason why this still happens. Deleting the line with "invisible ... library().." and adding 'library(R2HTML)' to .Rprofile does not solve the problem.

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 connectio...

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

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 explicitly, and I don't notice the bursts of disk activity in similar work without using my package. Any idea what might be causing a compressed file read? Something to do with lazy l...
