3D Plots
Good Evening,
I'm using R1.2.1.  Is 3D plotting available? The only reference I find
is to "plot.locfit.3d {locfit}" and the documentation says the function
is not currently available in R.
Any help is appreciated.

Vector Manipulation
Greetings,
I wonder if someone could point me towards a more elegent solution than
what I"ve kluged together.  I have a vector "samp1" of 296 integers.
They are sorted in ascending order and the numbers range from 177 to
228,953.  I'd like to specify N non-overlapping intervals covering the
range from 0 to 229,354 and then for each range, count the number of
integers from samp1

Help with Clustering Techniques in R
Greetings RListers,
I have a data set containing two types of outcomes; success and failure.
Associated with each outcome are 12  different measurements.  I'm trying
to find out, for example, if some of the 12 measures are associated more
with success or failure or, if there's any relationship at all between
the measures and the outcomes (success or failure).

data format issue
Dear all-
I have a dataset (see a sample below - but the whole dataset is June 
2005 - June 2008).  The "LST" format is "YYMMDDHHmm" and I would like to 
get the hourly average of the "mph" for the summer months (spanning all 
years). I have been trying to use "aggregate" but am not having much 
success at all!  any thoughts would be greatly appreciated.

Systematically biased count data regression model
Dear all,
I am attempting to explain patterns of arthropod family richness
(count data) using a regression model.  It seems to be able to do a
pretty good job as an explanatory model (i.e. demonstrating
relationships between dependent and independent variables), but it has
systematic problems as a predictive model:  It is biased high at low
observed values of family richness and biased low at

Time series questions
Hi, I am trying to teach myself some time series analysis.
I have some time series data on GDP, quarterly, from 1947 to 2011.  colnames
are "Year" "Quarter" "GDP" and "GDP.deflator"
The first problem I have is that 4th quarter 2010 is missing--not even NA,
there is no record for Year=2010 and Quarter =4, so instead of 260 rows, I
only have 259.  To solve
