Hi, I checked the archives, but I didn't find anything regarding this problem. FLAC__file_decoder_seek_absolute takes an incredibly long time to seek. What can I do about this? How do I fix it? Here's how I'm calling the function: if (argc > 2) { secs = atoi(argv[2]); seek_point = (FLAC__uint64) secs * sample_rate; printf("seeking to %d:%02d\n", secs/60,

sorry about the delay... first, yes you are calling it correctly. if your encoded files have max_framesize == 0, then that should mean that either 1) you were using the command-line flac to encode to stdout; or 2) you are using libFLAC directly. if 2, you can replicate the functionality that is in src/flac/encode.c:metadata_callback() to write back statistics and seek table to the metadata in

Hi, The following function works, but is there a neater way to write it? f = function(x,...) { # return a character vector of the arguments passed in after 'x' gsub(" ","",unlist(strsplit(deparse(substitute(list(...))),"[(,)]")))[-1] } > f(x,a,b,c*d) [1] "a" "b" "c*d" > Thanks. [[alternative HTML

r-help, Is there a package available for R which allows you to export data directly to .xls, much like exportData(foo,"foo.xls","EXCEL") in S-PLUS ? If not, is anyone working on this, or thinking about working on this? I apologise in advance if this question has already been answered. Many thanks, Matthew

Hi, n = 10000000 L = list(a=integer(n), b=integer(n)) L[[2]][1:10] gives me the first 10 items of the 2nd vector in the list L. It works fine. However it appears to copy the entire L[[2]] vector in memory first, before subsetting it. It seems reasonable that "[[" can't know that all that is to be done is to do [1:10] on the result and therefore a copy in memory of the entire

I think I figured out where the problem is. In my metadata_callback, I added a thing to print out the max_framesize and max_framesize from the stream_info block. Those are both zero. The ..._seek_absolute() function of the SeekableStreamDecoder uses the max_framesize to guess at where to seek. It doesn't seem to handle the case when max_frame_size is zero very well. I'm looking

Hi, Is there a function taking a function as an argument, which returns all the functions it calls, and all the the functions those functions call, and so on? I could use Rprof, but that would involve executing the function, which may miss some branches of code. I'd really like a function which looks at the source code to work out all the functions that could possibly be called. When I

Hi, In the example below why is d 10 times bigger than m, according to object.size ? It also takes around 10 times as long to create, which fits with object.size() being truthful. gcinfo(TRUE) also indicates a great deal more garbage collector activity caused by data.frame() than matrix(). $ R --vanilla .... > nr = 1000000 > system.time(m<<-matrix(integer(1), nrow=nr, ncol=2)) [1]

Is it intended that the first suffix can no longer be blank? Seems to be caused by a bug fix to merge in R 2.15.0. $Rdevel --vanilla DF1 = data.frame(a=1:3,b=4:6) DF2 = data.frame(a=1:3,b=7:9) merge(DF1,DF2,by="a",suffixes=c("",".1")) Error in merge.data.frame(DF1, DF2, by = "a", suffixes = c("", ".1")) : there is already a column
