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

readLines() and unz() and non-empty final line
But note:

updating: hello.txt (stored 0%)

[1] "hello"
I leave it to you and other wiser heads to figure out.
Cheers,

readLines() and unz() and non-empty final line
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

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.

readLines() and unz() and non-empty final line
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:

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:

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

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:
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"))

readLines() and unz() and non-empty final line
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"))

reading file in zip archive
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')

writeChar potential buffer overrun (PR#5090)
Trying to copy the (binary) header of a input file directly
to an output file, I've had repeatable seg faults. The call:
writeChar(hdr, outfh, nchars=6144)
when hdr just contains one empty string seems to be the
culprit. The stack traces weren't all that illuminating,
with sig 11 in memory-related functions following this. But
in src/main/connections.c it looks like do_writechar

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 zipped data directly from an FTP url

Sorry, I am clearly missing something here.
I want to read this file directly:

I tried using

But I got an error:

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:

COX PH models for event histories?
This is a question about the use of the Cox proportional hazards model to analyze event histories.
I am looking at the responses of sympathetic nervous system activity to a stimulus. The activity I observe is a burst that can only occur once per heart beat cycle (e.g., a binary count). Typically bursts occur in 60-80% of the heart cycles * sensory stimuli can modify these burst probabilities.

zip.file.extract on Windows
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,
