locfit questions/problems
Hi,
I'm trying to work through the examples and code in Loader's
LOCAL REGRESSION AND LIKELIHOOD, and have run into a problem
with the code for one sided smoothing and change point analysis
(p. 110-112).
The code, after loading locfit:
midp<-(1945:1988)+0.5
fitl<-locfit(thickness~left(year), data=penny, alpha=c(0,10), deg=1, ev=midp)
fitr<-locfit(thickness~right(year),data=penny, alpha=c(0,10), deg=1, ev=midp)
plot((preplot(fitr)-preplot(fitl))^2, type="b")
the error message crops up after the plot command and is:
Error in preplot(fitr) -...

smcp.shar (was linking object files)
...terface would need
rewriting to work on other data. I haven't tried running in R.
The methods can be implemented with locfit, using left and right smooths.
This example uses the penny thickness data (from Scott, Multivariate Density
Estimation, p234,276):
> midp <- (1945:1988)+0.5
> fitl <- locfit(thickness~left(year), data=penny,alpha=c(0,10),deg=1,ev=midp)
> fitr <- locfit(thickness~right(year),data=penny,alpha=c(0,10),deg=1,ev=midp)
To plot Delta-hat(t)^2 in S+ 5.0,
> plot((preplot(fitr)-preplot(fitl))^2, type="b")
In R, that would have to be

Conditional model in R
Hello all,
I have a data set where the response variable is the percent cover of a
specific plant (represented in cover classes 0,1,2,3,4,5, or 6). This data
set has a lot of zeros (plots where the plant was not present).
I am trying to model cover class of the plant as a function of both total
nitrogen and shrub cover.
After quite a bit of research I have come across a conditional approach

PDC Ldap adding computers to domain
I have a problem setting up samba using ldap as a domain server.
When I try to configure a windows 2000 machine to join the domain I
first get an authentication request where I enter root and roots
password. The dialog disapears for a while (20-30 seconds) and then
displays an error dialog with something like "The user name could not
be found" (but in swedish).
The computer name shows up
