Can somebody please take a look at this and tell me whats going wrong?
It seems to be parsing wronly around the 'if' statement and gives me a

help with bivariate density plot question
Dear R users:
I have a dataset with two variables (>20000 observations, two samples from same subject) and I used "kernSur" from library(Genkern) to
get a estimated bivariate density and corresponding plots as follows:
new.data.normal<-data.normal[!is.na(data.normal[,2]),]
x<-new.data.normal[,2]
y<-new.data.normal[,3]

resolution of windows metafiles
I am having trouble getting smooth-appearing curves in figures produced as
windows metafiles using R (R-1.1.1 on Windows 98). When I import them into
a word processor (either MS Word 97, or WordPerfect 9.0), the figures
appear only slightly bumpy on screen, but when printed, there is a clear
jaggedness reminiscent of aliasing. Is there a fix for this (if the answer
is "upgrade to 1.2",

R crashes when loading rgl package before minqa package
Hej,
Calling newuoa (from the minqa package) makes R crash when the package rgl

akima::interp "scales of x and y are too dissimilar"
Dear R users,
I want to do a fitted.contour plot of selected columns of a dataframe M with
M$AM and M$Irradiance as x and y axes respectively. The level of the contour
shall be determined by M$PR.
Some words on my data first. Dataframe M looks like:
head(M$Irradiance)
[1] 293 350 412 419 477 509
head(M$AM)

R Newbie Question
Hello list,
I just started R today and tried something quite simple. I wanted to
create a colored plot and eventually after hours of fiddling around got
it working. However, my solution seems very suboptimal and I'd really
appreciate your hints on how to improve. I believe that R already offers
many functions I coded (e.g. distance between two vectors, vector
length, vector normalization and

ncdf4: Why are NAs converted to _FillValue when saving?
Dear all
I'm a newbie regarding netcdf data. Today I realized that I maybe do not understand some basics of the netcdf. I want to create a *.nc file containing three variables for Switzerland. All data outside of the country are NAs. The third variable is calculated from the first two variables. Basically there is no problem to do that. I copy the file with the data of the first variable,

Using "mean" if two values are identical
Hello,
I have got a question.
I've got a matrix (mail end) with the colnames x, y, z. In this matrix
are different measurements. x and y are risign coordinates.
My question. Always, if the "x" AND "y" coordinates are the same, I want to
get the mean of their z values.
e.q. "
x" AND "y" in line1 and line8 are identical:

help with scatterplot3d
Hello,
I am having a bit of trouble with scatterplot3d().
I was able to plot a 3d cloud of points using the following code:
>my.3dplot<-scatterplot3d(my.coords, pch=19, zlim=c(0,1), scale.y=0.5,
angle=30, box=FALSE)
where my.coords is a data frame that contains x, y, and z coordinates for
grid points whose elevation we sampled.
The problem occurs when I try to add points using points3d.

plotting a grid with color on a map

I have posted similar questions regarding this topic, but I just can't seem

Basically, the attached file is a 5 degree by 5 degree grid of the the world

akima interp results to zero with less than 10 values
The akima package has a problematic license (it doesn't allow commercial
use), so it's been recommended that people use the interp package
instead. When I use interp::interp instead of akima::interp, I get
reasonable output from your example.
So that's another reason to drop akima...

Alternative to interp.surface() offered
I wanted a simple function for bilinear interpolation on a 2-D grid, and
interp.surface() in the fields package didn't quite suit my needs. In
particular, it requires uniform spacing between grid points. It also
didn't have the "visual" reference frame I was looking for. Here is an
alternative function, followed by an example.

interp.surface() error (PR#7745)
R version: 2.001

When I use the interp.surface() function, on occasion I have encountered
the following error message:

Since it is somewhat dependent on the data set, I cannot say exactly in
which cases these occur, but I believe I have found the problem and a

Dear R-users,
I build already many contour graphs using the contour-procedure in R (akima library), after interpollating my data z on x,y (see e.g. graphs in this paper: http://www.biomedcentral.com/content/pdf/1471-2148-9-16.pdf).
Now, however, i experience unexpected and completely unsensible problems: after building the syntax, i can create the graphs and use the interp-command without any

interp equivalent
Hi
I'm looking to a function in R equivalent to S-PLUS' "interp".
Is there any implementation in R?
If not, is there any similar interpolation function such that at
the data points the interpolated values concides with the data?
Thanks in advance
