Hi, I have a data frame where one column is a list of lists. I would like to subset the data frame based on membership of the lists in that column and be able to 'denormalise' the data frame so that a row is duplicated for each of its list elements. Example code follows: # The data is read in in this form with the c2 list values in single strings which I then split to give lists: > f1 <- data.frame(c1=0:2, c2=c("A,B,C", "A,E", "F,G,H&...

...tion stays below 4%. This is a great improvement. So how can I fix this to work with floating point ? Thanks.

Just to make sure, can you try compiling in fixed-point (FIXED_POINT) and see if the problem goes away (it's not a fix, just a test)? If that's the case, there's probably a few VERY_SMALL's to add to some signals. Cheers, Jean-Marc Mark Schill...

Hi, I have a curious problem with speex. As long as I'm talking, it takes about 2-5% of my CPU. This seems ok. But as soon as I stop talking, CPU utilization rises to about 30-45% and stays there until I start talking again. I compiled speex from source and use it with these settings: - Preprocessor: Denoiser = ON, AGC = ON - Encoder: ABR = 15000, DTX = 1, Mode = narrowband, Rate = 8000 Hz.

...t I'm not sure.
