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

Hi all, in the last time I've intensively used Rstreams to read and write from binary files. Now I'm wondering if it is possible to use Rsteams functions with gzipped files. But I haven't found the trick: > p1c.gzip <- gzfile("daten/p1c_all.mea.gz", open="rb") > readBin(p1c.gzip, integer(), n=64,size=2) [1] 84 1 400 1 749 0 0 0

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

Full_Name: Hugh C. Pumphrey Version: 1.4.1 OS: Linux (Debian Woody) Submission from: (NULL) (129.215.133.170) The function readChar() appears to have some type of problem with memory allocation. I don't know if "memory leak" is the correct term but if one uses readChar() many times, the R binary grows in size until it eats all your memory and swap space. The code enclosed below

Is there any way to write (8-bit) bytes to a file which works on all [R] platforms? I have been looking at 1) writeBin 2) writeChar 3) cat and neither of them manage to write arbitrary sequences of bytes (0-255). For instance, I would like to create a binary file of length three containing the bytes 0, 1 and 0. I [R] I have the following vector of bytes: bfr <- c(0,1,0) 1) For

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.

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

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 there, anybody knows how to import data into R from splus directly? I have a huge amount of data in splus format, which will cost forever for me to transform the data back to ascii or something else and then read them into R. thanks a lot. ximing -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hi everyone, Has anyone written a parser in Java for either the ASCII or binary format produced by save()? I need to parse a single large 2D array that is structured like this: list( "32609_1" = c(-9549.39231289146, -9574.07159324482, ... ), "32610_2" = c(-6369.12526971635, -6403.99620977124, ... ), "32618_2" = c(-2138.29095689061, -2057.9229403233, ... ),

system.file("",package") is documented to return the root of the package (as it did in the past). It actually returns "" (Win98, R1.3.0), breaking the SJava package Omitting the first argument does work correctly and so is a workaround if the argument is explicitly "" but not if it is the value of a variable. -thomas

Dear Sir, I am using R for the first time and I am looking for a function or a command that allows to import Splus data into R. I have already heard about functions called "readSdata" and readSfiles" in the "Rstreams" package. I did not find the last new version of this package on the CRAN and its old one did not work on R 1.8.0 (the vesrion that I am using). Would you

I have used S-Plus for Windows for some time and have a large collection of personal programs. I have recently installed R-1.1.1 under Linux. I can read the .ssc files from S-Plus into emacs and save to R, but this is apt to be tedious. Any shortcuts to recommend? Will linux R read the _Data files from Windows S-Plus? Would Windows R serve as a useful intermediate transfer? -------------- next

Is it possible for R to "read in" S objects. For example, suppose that when using S I did: > x <- c(1,2,3) > y <- x^2 > q() These objects are now in the .Data directory. If I then want to use x and y in an R session, how can I do so? Thanks, Rob -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

I see in the devel snapshot there is a new generic method > truncate function (con, ...) UseMethod("truncate") which conflicts with a generic method in one of my packages: > truncate function (x, start = NULL, end = NULL) { UseMethod("truncate") } I don't think there is a problem, but there used to be a recommendation to use the same name for the first

Dear R-friends, i just look at http://www.statistik.uni-dortmund.de/leute/ligges.htm to download scatterplot3 and saw a write and read wav-files library. So i wondered if R can play wav-files. This would be very practical, espacially when you do some long computations. If not, can R play a system beep or something like that? Thanks, Thomas
