non-consing count
...ever, this approach allocates and discards 2 vectors: a logical
vector of length=length(x) and an integer vector in which.
is there a cheaper alternative?
Thanks!

merge(join) problem
...keep just _one_ row with the same Name & Open - and the
largest Time.
How do I do that?
unique() seems to have the right name, but I don't see how it can help me...

all.equal: subscript out of bounds
When I do
> all(all$X.Time == all$Y.Time);
[1] TRUE
as expected, but
> all.equal(all$X.Time,all$Y.Time);
Error in target[[i]] : subscript out of bounds
why?
thanks!

summary for factors is not very informative
...much more useful if it additionally
printed frequency stats as if by
summary(aggregate(frame$ColName,by=list(frame$ColName),FUN=length)$x)

vectorization & modifying globals in functions
...lobal d is not modified, apparently update modifies the
local copy.
so,
1. is there a way for a function to modify a global variable?
2. how would you vectorize this loop?
thanks!

a merge() problem

(when I omit suffixes, the result is the same).

plot means ?
Hi,
I need this plot:
given: x,y - numerical vectors of length N
plot xi vs mean(yj such that |xj - xi|<epsilon)
(running mean?)
alternatively, discretize X as if for histogram plotting and plot mean y
over the center of the histogram group.
is there a simple way?
thanks!

string parsing
...ts,
but I am wondering if I am doing it "the right R way".
E.g., the hash table value is a data frame.
A structure(record?) seems more appropriate.
thanks!

qqnorm & huge datasets
Hi,
When qqnorm on a vector of length 10M+ I get a huge pdf file which
cannot be loaded by acroread or evince.
Any suggestions? (apart from sampling the data).
Thanks.

multi-column factor
...handle this?
maybe there is a better way to extract levels than union()?
(bear in mind that I have ~10M rows and ~1M levels, so performance is an
issue).
Thanks!

cannot turn some columns in a data frame into factors
...ALSE FALSE FALSE FALSE
i.e., there is a column named "Month" (the 1st column), and it is indeed
turned into a factor inside sapply(), but after that it is numerical
again!
what am I doing wrong?
