Lattice bwplot error
...here the error
occurred (there are more than 11,000 data points). However, I had no problem
using boxplot() to generate four graphs separately:
> boxplot(dev ~ Dbhcl, data=DbhValid2[DbhValid2$period == 5,])
Any ideas and suggestions?
TIA,

Optimization failed in fitting mixture 3-parameter Weibull distri bution using fitdistr()
...without problems. With a limited experience with the
fitdistr(), it seems to me, similar to all nonlinear or optimization
procedures, the starting values are critical for convergence. Any
suggestions for solving the optimization problem?

r-square for cluster
...tot_grid40km) #withinSS (??) as the sum of SS for all clusters
ssbetween_grid40km = SSTot-ssw_grid40km
RSQ_grid40km2 = ssbetween_grid40km/SSTot # R-square
Am I right? Does this correspond to SAS's R2?

create a color palette with custom ranges between colors
Hello everybody,
I'm trying to create my own color palette on R, in order to interpolate some
different temperature data on different maps (daily means, seasonal
means,...).
I would like to create a color palette which works for each map, so I need a
color palette between -40 and +40?C. Sometimes my data for one map range
from -10 to +20, sometimes from 10 to 30, etc... but always between
