[R] ROCR package partial false positive and accuracy

Hi, In the ROCR package is there a way to find the accuracy that corresponds to a given false positive rate. In version 1.0-2, the authors of the package added an option to find the partial area under the ROC curve up to a given false positive rate by passing an optional parameter fpr.stop: perf.au

Re: [R] SUM,COUNT,AVG

This is a good example to compare different approaches. My understanding is aggregate() can apply one function to multiple columns summarize() can apply multiple functions to one column I am not sure if ddply() can actually apply multiple functions to multiple columns? This is what I would like to

Why don't you use something like this to plot without having to extract the clones: xyplot(height~year|factor(clone), x, group=code, layout=c(3,2)) On Mon, Apr 6, 2009 at 6:11 PM, Schreiber, Stefan wrote: > Hi there, > > I hope you guys can help me with the following: > > If have a file like

Re: [R] how to subsample all possible combinations of n species taken 1:n at a time?

If I understand your problem properly, you could just note that selecting 1:n of n objects is the same as deciding separately whether each one is included or not. (exclude the case where none are selected). Take 1000 of these and you are there- except some are duplicates - so generate extras and

Re: [R] how to subsample all possible combinations of n species taken 1:n at a time?

If you want 128 combinations, then generate 8 16-bit random numbers and concatenate them together. You will have to check for dups as you generate the sequence, but it is at least a start and should fit within the memory of the system. On Mon, Apr 6, 2009 at 7:39 PM, David Katz wrote: > > This i
