Ifs in formula
Dear r-helpers,
This might be an elementary question, but I have a hard time getting
my head around it, so all help is much appreciated.
I am working on a nonlinear regression model of the form
if z > 0
y = f1(x,y),
else
y = f2(x,t) .
In other words, the functional form of f(.) changes according to some
criteria z. Natural approach would be to fit two models, i.e.
model1 <- nlm(y ~ ...,

npreg: plotting out of sample, extremely large bandwidths
Hello r-help,
I am using the excellent np package to conduct a nonparametric kernel
regression and am having some trouble plotting the results.
I have 2 covariates, x1 and x2, and a continuous outcome variable y. I
am conducting a nonparametric regression of y on x1 and x2. The one
somewhat unusual feature of these data is that, to be included in the
dataset, x1 must be at least as large as x2.

The npRmpi package (parallel np package for multi-core environments)
Dear R users,
A parallel implementation of the np package titled `npRmpi' is now available on CRAN. This package can take advantage of multiple core computing environments to reduce the run time associated with the methods contained in the np package.
Kindly see the vignette for details and examples on modifying np code and running it in a parallel environment. You are requested to seek

New package `np' - nonparametric kernel smoothing methods for mixed datatypes
Dear R users,
A new package titled `np' is now available from CRAN.
The package implements recently developed kernel methods that seamlessly
handle the mix of continuous, unordered, and ordered factor datatypes
often found in applied settings.
The package also allows users to create their own
nonparametric/semiparametric routines using high-level function calls
(via the function npksum())

Package plm & heterogenous slopes
Dear r-helpers,
I am working with plm package. I am trying to fit a fixed effects (or
a 'within') model of the form
y_it = a_i + b_i*t + e_it, i.e. a model with an individual-specific
intercept and an individual-
specific slope.
Does plm support this directly?
Thanks in advance!

Modifying values into XML with R
Dear R gurus,
I use R all the time at work, so one day a problem managing my personal arise data made me think: "Why not use R, it does everything!".
Anyway, my goal is to use R to manage my personal music library, and more precisely my playcounts. I have two XML files, one from Winamp and the other one from Itunes. Both have pretty much the same songs, but their playcounts are

Local linear regression
Dear all,
I wrote a code which supposedly should create a function which performs a
local linear regression at point x (lower case).
The issue is that I have no reference to check if indeed my code performs
correctly a local linear regression. Is there any function in R that
performs a local linear regression (to give conditional expectation which I
am interested in and not graph) in order to

Bandwidth selection for ksmooth( )
Dear R Users,
Before running ksmooth( ), a suitable bandwidth selection is needed. I use some functions for this task and receive these results for my data:
width.SJ(y,nb=100,method="ste") : 40.25
bcv(y,nb=100) : 40.53
ucv(y) : 41.26
bandwidth.nrd(y) : 45.43
After implementing the function ksmooth(x,y, bandwidth= each of abovementioned bandwidths), I have some NAs
