Hi all
How to make from a n x m matrix with the stack command 2 categorical
factors in R, the row and the col factor?
Is there a function for nice graphical outputs in ANOVA?
Thanks

Hi all
how to find a function for plotting polygon surface, like
polgon3d(xc,yc,obs)
xc, yc ... coordinates
obs observations
result: persp plot with grid net over the coordinates

I have set of n coordinates xc, yc (but not a grid!) and n observations obs
at these points.
Where to find a simple plot function (3D perspective) that plots a polygon
(alternative: just segmented points over a map, as eg in library maps).
rgl.surface(xc,yc,obs) is not working.
Thanks

Why is the option "last changed" not working if I open a script from R
under Vista?

Strange things are going on in R, if you reshape a matrix in R:

Hi all
Maybe someone knows a way to solve this anomaly in sample():
I like to compute a sample (n=100) with replications from a population of
2500 units but if I draw repeated samples from it I dont get what seems to
be a representative sample if I look at other partitions of the population.

I want to make a contour plot estimate based on a sample of points -- a
sort of smoothing.in 2D (but also in a scatterplot)?
Any ideas
