unexpected behavior from gzfile and unz
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....

unz()
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:

Mysterious behavior
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

Looking for example of usage of function unz
I would greatly appreciate some example of correct usage of function unz.
I have to download and uncompress the following web compressef file:

how to unzip files in R
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

unz( "x.zip", "y.csv" ) != pipe( "unzip -p x.zip y.csv" )
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...

unz() ignores encoding argument
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...

opening a file from within a zipfile that is online
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.

reading file in zip archive
...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.

Reading zipped data directly from an FTP url
...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!

Passing R connection as argument to a shell command on Windows
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)

zip.file.extract on Windows
...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,

I have ever install cygwin and now I try to install R.

opening a WinZip file

Extension provokes crash in unzReadCurrentFile
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...
