anyone know why package "RandomForest" na.roughfix is so slow??
...t say for sure: my "predict" data
sets are MUCH larger than my model data sets, so cleaning the prediction
data set simply takes much longer.)
If so, any ideas how to speed this up?
Thanks!

manipulating the Date & Time classes
...d chime in with any strange behaviors they've seen in
working with times, maybe we could get a critical mass of issues that are
worthy of an overhaul.
Thanks & Regards,

question regarding "varImpPlot" results vs. model$importance data on package "RandomForest"
...ust right. But
I am not sure which is accurate: the varImpPlot or the $importance
section. Which should I trust more, especially when they disagree
appreciably?
Thanks!

ideas, modeling highly discrete time-series data
...9;t the best forum, since I
know this is not specifically an 'R' question, please let me know of a
better forum to post such a question.
Thanks!

How to get 'R' to talk BACK to other languages / scripts??
...I could write to a csv file & read that file, but that seems
a REALLY clunky way to handle variable passing.
Thanks for any help!

how to convert "sloppy data" into a time series?
...is because I next want to be able to use
all the very nice modeling capabilities that a univariate time series
allows, such as arima, etc.
Thanks in advance!

odd behavior of "summary" function
...of the 2 also seems "reasonable". Either way,
"summary" is calculating the wrong number, and most disturbing is that it
mis-calculates the max.

syntax for extending a line in a script??
...continuing? Something like
python's "\" at the end of a line? I tried wrapping the whole thing around
curly braces { } but that didn't work, either.
Thanks!

how can I evaluate a formula passed as a string?
..." function doesn't work
as it should. How can I get, for instance, "length(unique(x))" (as a
character string) to become length(unique(x)) (a function to be evaluated
as shown above).
Thanks!

trouble with RODBC -- chopping off part of column names
...ot even sure how to debug, and I can't
really get around this because I cannot simply query all of the columns, the
data set would become too large.
Thanks!

ggplot2 histograms... a subtle error found
...ading
the actual data. If I simply attach it, will it be received by r-help?
Hadley, if you're interested, would you like me to send you the data
directly to you?
