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 while (s$position <= s$size) { : missing value where logical needed Is it possible to read data from t...

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

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

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

Thanks for your help on moving files from S+ to R and on attaching directories. If attaching directories is NOT possible in R, is there any other way to separate objects into different folders or something similar? For example, to keep user functions for multivariate analysis in a different "place" than user functions on time series, or to keep data objects of project_1 in a different
