similar to: Using lib Rstreams and gzfile()

Hi there, I want to read all data from a binary file (with package Rstreams). I tried the following function (small piece of code): readdata <- function (file) { # open file s <- openstream(file, "read") # read int values while (s$position <= s$size) { readint(s, 1, 2) -> type [...] } return() } and got the following error: > Error in

Dear R-helpers, I am trying to install Rstreams library on the following platform: ---------------------------- platform alphaev67-dec-osf5.0 arch alphaev67 os osf5.0 system alphaev67, osf5.0 status major 1 minor 2.3 year 2001 month 04 day 26 language R --------------------------- Unfortunately, I get these error messages: --------------------------- > [557] R

Hello, I'm looking for a working compiled library of "rstreams" for mac OS 9 and for mac OS X. I could find one (somewhere) but it is not loading. It says in R 151 under OS 9.2: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "PRO-096-system:Applications:Languages:rm151:library:rstreams:libs:RstreamsL ib": error code -2807

This is just to let people know that I'm going to try to put together a little package of binary file read/write functions for R, along the lines described in my message in r-help. I'm going to do it first in R for Windows using a DLL written in Delphi; I'll let people comment on that, and once the design settles down, I'll redo the external code in C so that it should be portable

Dear R-users, I successfully installed the package Rstreams under linux, but my first attempt to do so on SGI IRIX 6.5 (64bits) lead to the following error message. -------------------- laurent at genome> R CMD INSTALL Rstreams Installing source package `Rstreams' ... creating cache ./config.cache checking for ftruncate... yes checking size of long double... 16 updating cache

I am trying to run the Samsung's EasyGSM program.

I was just playing around with the R-streams package, reading in some data from an old experiment we did here, and was again amazed by the flexibility of the R environment. The eaze with wich I was able to generate simple plots of my EEG data made me wonder if someone tried to implement an ERP package. For the non-cognitive scientists ou there: EEG is electrical activity measured from the scalp

Hi, I came into a crash when using 32-bit `speexdec` and found that there's an address overflow in function `print_comments()`: static void print_comments(char *comments, int length) { char *c=comments; int len, i, nb_fields; char *end; if (length<8) { fprintf (stderr, "Invalid/corrupted comments\n"); return; } end = c+length;

Hi all. I'm trying to install the packages Rstreams and RPgSQL, but with no success. I did R INSTALL name package but if I try library(Rstreams) I get the following error: Error in library.dynam("Rstreams",pkg,lib): dynamic library 'Rstreams' not found Error in library(Rstreams): .First.lib failed Where did I go wrong? I'm using R 1-1-1 on a Debian GNU/Linux box.

Hi list, Today i tried upgrading my dovecot server from 0.99.14 to 1.0alpha3. Unfortunately the new version does not work.

Hi, I am making multiple calls to gzfile() via read.table(), e.g. > x <- read.table( gzfile( "xxx.gz" ) ) After i do this many times (I haven't counted, but probably between 50 and 100 times) I get the error message: Error in open.connection(file, "r") : unable to open connection In addition: Warning message: cannot open compressed file 'xxx.gz' however, I

Hi, I have some text files that do not have trailing \n on the last (incomplete) line; how do I read in the last line? e.g. here is a test case: [linux + R version 2.6.1 (2007-11-26) ] z <- gzfile("short.gz", open="w") cat("7\n5\n3", file=z) close(z) z <- gzfile('short.gz') readLines(z) [1] "7" "5" readLines would indicate that

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}}

Found the simpliest way of seeing I bug I encountered doing "R CMD check --use-gct": Just launch R (with --vanilla), and do this: > ?gctorture # this work > gctorture() > ?gctorture Error in gzfile(file, "rb") : can only weakly reference/finalize reference objects # this does not It seems that when gctorture() is on gzfile() doesn't work.

Hi, I get an "internal error" when calling seek() twice on a gzfile connection. Create a gzip file: bigraw <- sample(charToRaw("abcdef"), 30000000, replace=TRUE) save(bigraw, file="bigraw.rda") Open it: con <- gzfile("bigraw.rda", "rb") Then: > seek(con, where=1) [1] 0 > seek(con, where=24980000) [1] 1

I don't know if this is a bug per se, but an undesired behavior in read.dcf. read.dcf takes a file argument and passes it to gzfile if it's a character: if (is.character(file)) { file <- gzfile(file) on.exit(close(file)) } This gzfile connection is passed to readLines (line #39): lines <- readLines(file) If no newline is at the end of the file, readLines

Would it be possible to get that file or a representative subset of it somewhere so that I can reproduce this?

Hi all, I used `gzfile` and `gzcon` to read a compressed file but I found that `gzcon` gave me a different result than `gzfile`. It seems like the `gzcon` does not handle the data correctly. I have posted an example below. In the example, a portion of a compressed file is downloaded from Google Cloud as a raw vector, and the data is saved into a temp file. If I use ` gzfile` to read the file, it

Hi all, My code: x <- scan(gzfile("file"),what='integer') x is imported, but as mode "character" rather than "integer". I know I can do as.integer() when importing, but am still trying to figure out why the above occurs. When I do summary(as.integer(x)), there are no NAs introduced by coercion, so the vector really is all integer. Also, is the above
