xapian-letor: FeatureVector discussion
...scussion.
Presently, the FeatureVector class is defined as follows, with a fixed
number of feature count (19):
class FeatureVector::Internal : public Xapian::Internal::intrusive_base{
friend class FeatureVector;
double label;
double score;
std::map<int,double> fvals;
int fcount;
Xapian::docid did;
The two approaches that were discussed were:
1. Using enums as IDs for features in fvals.
2. Making fvals into a configurable vector of feature values.
The issues were that the first way would still assume an order in which the
features occur, and the second way would requ...

fcolors[i], :
Error: X11 cannot allocate additional graphics colours.
Consider using X11 with colortype="pseudo.cube" or "gray".
However, if I use "pseudo.cube" I don't get anywhere near enough
distinct colours. I could use gray, bu...

function pointers?
We have a project that calls for the creation of a list of many
distribution objects. Distributions can be of various types, with
various parameters, but we ran into some problems. I started testing
on a simple list of rnorm-based objects.
I was a little surprised at the RAM storage requirements, here's an example:
N <- 10000
closureList <- vector("list", N)
nsize = sample(x
