Dear All I hope that someone can help.
I am working with sp pakage and akima

imagine lots of different dataframes, of row = 100 columns = 3 of x and y
coordinates with z values I will call these data frames for the sake of this
example akima

producing 100 dataframes dataframes of the form akima[[i]]

Lattice help: Dotplot
With Dotplot, I'm trying to make a figure that will ultimately have the same

y-axis will consist of a different label for every point. Here's my code:

How to translate the 2D-density matrix (the output of bkde2D function) into matrix of datapoints' amounts?
It is known that function bkde2D (package "KernSmooth") returns a matrix of
density estimates over the mesh induced by x1 and x2. In Details it is
written that "... heights of the kernel, scaled by the bandwidths, at each
datapoint are summed. This sum, after a normalization, is the corresponding
fhat value in the output".
There are several questions:

PXELINUX [BIOS] 6.02 - Upgrade to 6.02 from 4.07 introduces local boot regression
Hello All, this is my first post so I'll try to be as verbose as possible.

xyplot help - colors and break in plot
Dear List,
I am new to lattice plots, and am having problems with getting my plot to do what I want. Specifically:
1. I would like the legend to have the same symbols as the plot. I tried simpleKey but can't seem to get it to work with autoKey. Right now my plot has dots (pch=19) and my legend shows circles.
2. I have nine groups but xyplot seems to only be using seven colors, so two

I''ve got a rails app which is basically an admin interface to a xml

Display Median in plot
Hi,
I drew a plot with R of my data and now I would like to display the
median values of each group
above the respective datapoint in the plot. I already search for ages,
but maybe I am just blind.
I am sure that this has to be an option somewhere...
I appreciate any kind of input!

Problem with x labels of barplot
Hello everyone,
i am currently creating a barplot.
This barplot takes a vector of ~200 datapoints.
Each datapoint represents one bar.
http://img96.imageshack.us/i/human1w.png/
(Ok as you see, it is not only one barplot, but a series of barplots).
Now, these barplots represent a human chromosome. This means they are
ordered. For instance bar number 50, means position 50 in the human
chromosome.

I have been a little too busy and have not yet upgraded to 18.04 so I can't
attempt to replicate -- but it _looks_ just like a garden variety binary

R question about prediction from a fitted model
Hi, I have a question about predicting new values from a fitted model in R.
For example, if i fit a linear model
fit<-lm(y~x)
predict(fit) will give the fitted values for each x.
I am wondering if there is a way to do some prediction of the fitted for
some new values of x that are not in the data points?
for example, x=0.5 is not in the original data (not a datapoint), is there a

Extracting clusters from Data Frame
Hello,
I have a large data frame (1006222 rows), which I subject to a crude

something like this:
Value Cluster?
