x and y lengths differ
I have a problem with R. I try to compute the confidence interval for my
df. When I want to create the plot I have this problem: Error in
xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ.
I try this code:
library(dplR)
df.rwi <- detrend(rwl = df, method = "Spline",nyrs=NULL)
write.table(df.rwi,file="rwi.txt",quote=FALSE,row.names=TRUE)

avas and ace
Hi,
Does any one know how we can decide on the correct transformation in (avas and ace) after having drawn the graphs y,g(y) x ,s(x) and g(y) ,s(x) . Is it possible by only looking at patterns the graphs follow for example when
y ,g(y) shows a logaritmic pattern can we say that log transform on y is suitable?
Thanks for your help.

sample(c(0, 1)...) vs. rbinom
Greetings.? My wife is teaching an introductory stat class at UC Davis.? The
class emphasizes the use of simulations, rather than mathematics, to get
insight into statistics, and R is the mandated tool.?? A student in the class
recently inquired about different approaches to sampling from a binomial
distribution.? I've appended some code that exhibits the idea, the gist of

simple intro to cluster analysis using R
I am looking for simple introduction to cluster analysis using R, that would
be understandable to a novice in statistics. Or, could someone perhaps help
me understand how to proceed in my analysis? I am very new to both statistics

me...

ACE/AVAS with bootstrap
I am using ACE/AVAS to fit a non-parametric regression model to a multivariate data set. Is there a way to add confidence intervals to the fit and predictions by using bootstrap? Thanks for any suggestions.

[LLVMdev] 2.1 Pre-Release Available (testers needed)
Hi,
LLVM 2.1-pre1 test results:
Linux (SUSE) on x86 (P4)
Release mode, but with assertions enabled
LLVM srcdir == objdir
# of expected passes 2250
# of expected failures 5
I ran the llvm-test suite on my desktop while I was also working on that PC,
so don't put too much trust in the timing info. Especially during the "spiff"
test the machine was swapping

Routes
hi all,
I want to move some routing tasks out of the router and into the
controller. The goal is to make Merb feel less like mod_rewrite and
give the user more control at the controller. The new Router is
simple: it takes the path_info (not the whole request) then outputs a
controller class and some parameters from the path matching. The rest
of the routing would be done at the controller level.

vector is not assigned correctly in for loop
Hi there,
Here is a minimum working example:

lower = 0
upper = 1
n_bins = 50
interval = (upper - lower) / n_bins
bins = vector(mode="numeric", length=n_bins)
breaks = seq(from=lower + interval, to=upper, by=interval)
for(idx in breaks)
{
bins[idx / interval] = idx
}
