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 the start to the finish of a stream? Thanks, Sven -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-...

...ng 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 to Unix as well. One immediate change from my first pass suggestion below: I'll just have readint, readfloat, readchar; the size and whether signed or unsigned will be determined by parameters to those functions. Other suggested changes are welcome! Duncan Murdoch >I think a set of stream like functions would be really handy >sometimes, especially for those of us who aren't that co...

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, ... ),

...sec. no matter what I am trying. When I run zpool iostat <pool> 1 while reading a big file from the share, I can see that the pool has continous reads of about 50 to 60 MB/sec. and I am getting approx. 30 MB/sec on the client. Afterwards the files must reside in the ZFS file cache, since readint he same file again, will not show any read activity on the pool at all, but the transfer rate is still quite slow - a max. of 45 to 50 MB/sec. When I use dd on the host itself to copy the file from the pool to /dev/null I am getting approx. 120 MB/sec, which is still way more than the 30 to 5...

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

You are citing the "Android platform workflow" section, which is about sanitizing components of the Android system itself. For NDK apps, see "Android NDK workflow" in the same document. You need -eng build because preloading libraries into dalvik vm is not allowed in user builds. JellyBean includes several bugfixes in the dynamic loader that asan needs. Was there any useful

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

Hi Jim, Thanks a lot for investigating. It definitely makes sense now. I'll fix the problem now. Is there any other place where you see that same (or similar) problem?

I'm not advocating AAA. However this is a proposal for more modern thinking regarding the permissiveness of auto in LLVM codebases. Currently the rule on the use of auto is here: https://llvm.org/docs/CodingStandards.html#use-auto-type-deduction-to-make-code-more-readable It is quite strict. It allows the use of auto for * lambdas * iterators because they are long to type * casts to
