Kernel density
Hi,
I want to fit a kernel density estimator by bkde of library KernSmooth.
I need only the density value at the point 0.
I do not understand the following behaviour:
> q <- rnorm(100)
> bkq <- bkde(q, bandwidth=0.11, gridsize=1, range.x=c(0,0))
Error in 0:L : NA/NaN argument
> bkq <- bkde(q, bandwidth=0.11, gridsize=1, range.x=c(-1,1))
> bkq
$x
[1] -1
$y
[1] NA

extend question
Is it possible to call the super class''s version of a function from a subclass?
SuperClass = Class.create();
SuperClass.prototype = {
initialize: function(){
this.varA = '''';
this.varB = '''';
}
}
SubClass = Class.create();
SubClass.prototype = (new SuperClass()).extend({
initialize: function(somevar) {
this.somevar = somevar;

about dpik
Thank you for your reply.
I know the x in dpik() means the vector. But I don't know how to import into
c() with a huge metadata (>1000).
Following is my some try, and the h is: [1] 0.001180569, which seems to be
feasible.

Help understanding EVERYTHING
Team,
I am trying to learn a GUI for Ruby and I picked wxRuby.
The problem is that I am kind of slow learning this and I now feel
frustrated after trying for about at least 7 hours.
I am trying to design a simple Sudoku 9x9 grid to display numbers, 1 - 9,
using buttons.
I posted a question on Ruby forum ruby-talk and a gentleman, Alex Fenton,
answered my questions.

surface3d grid from xyz dataframe
Hi List,
I am trying to plot a grid with an overlayed height. I have a dataframe
with four variables:
x,y,gridvalue,height. The dataframe has 2.5mio observations (ie grid
points),
I assign colors through the gridvalue using map_color_gradient thus
producing:
x,y,gridvalue,height,gridcol as variables of the dataframe. The grid
dimensions are 1253 x 2001 (=2507253 data points).

Layout Issue ...
The following program represents the basic layout of my application. The
problem I have is that the panel, and thus, the grid does not resize
when the window width is expanded.
Also, I would like the entire grid to be displayed without the
horizontal scroll bar. How can I force this behavior?
Please tell me if I am going about this incorrectly. I am just getting
familar with wxRuby and any

density plot on a log scale
I'm working with a large dataset - large enough that when I do a scatter plot
the points all blur together, so I want to plot their density by color - a
heat map or something like that. I've used smoothScatter for tasks like
this, but the problem is that my current dataset really only looks good on a
log-log scale. When I do the following command

bkde() breaks
Hello,
I've been using the KernSmooth package recently and think I have found a
problem with it:
after loading the library I can issue
bkde(c(27,26,27), bandwidth=dpik(c(27,26,27)), range.x=c(4.4, 113.6),
gridsize=128, truncate=T)
and bkde returns an error. If I change the gridsize to 129 the function
works perfectly. I have tried this on my Linux box, and on a nearby
Solaris machine, both

locpoly (was: no subject)
1. Please do make use of the subject line.
2. Please (re-)read the description of the `range.x' argument in ?locpoly:
it's suppose to be a vector of min and max x values.
3. I hope you realize how grossly inefficient this computation is...

loess and locpoly
Dear list,
I've got a question concerning difference between loess and locpoly. I have to use a plug-in method to chose a bandwith so I take locpoly method to fit a curve.
My problem is:I know how to get predicted values in loess:
m=loess(y~x)
y_fitted=predict(m).
But how to get the same in locpoly? I computed like this:
bw=dpill(x, y, blockmax = 5, divisor = 20,trim = 0.01, proptrun =

About dpik function
Hi there and thanks in advance.
Nowadays I am working on the plug-in bandwidth selection with R. Firstly, my

Secondly, my code is following:

A couple of draggable patches...
Hi all,
I've just raised a ticket <http://dev.rubyonrails.com/ticket/2826> with a
patch for enabling 'snapToGrid' feature for draggables.
I'm writing a framework on top of scriptaculous and it appeared to me that
this would be something that could belong to core Draggable objects.
To activate, just add to draggable options on creation. (By default gridSize
is set to 10)

problem using "by" with custom function?
Hi,
I'm relatively new to R and R development, so please forgive me for any
obvious errors.
What I am trying to do is use the command dpik within the package KernSmooth
to estimate bandwidth parameters for GPS telemetry data. I have been able
to get this to work on a case by case basis without any problem, but would
like to extend this so that I can batch process many different animals for

mutual information for two time series
Hi I hope this is going to the right place. I am trying to write a program
which uses KernSmooth library to estimate mutual information between two
time series at various different lags. At the moment it’s producing negative
values, which is supposed to be impossible (something is fishy). I am
summing across one row of the matrix to get p(value is in bin x) and summing
across the columns to get
