[Fwd: Re: Fw: Contour plot]
...z~I(x^2)+y, data=dat)
>dat.lm
Call:
lm(formula = z ~ I(x^2) + y, data = dat)
Coefficients:
(Intercept) I(x^2) y
1.841e-14 1.000e+00 1.000e+00
How do I create the "z" matrix from dat.lm?? Without having to type over
all the coefficients?
Kind regards, Darius Blaszijk

Contour plot
...I would like to make a contourplot of the following data;
> x <- 1:10
> y <- 1:10
> z <- 100:110
By doing >contour(x,y,z) I get the following error;
"Error in contour.default(x, y, z) : no proper `z' matrix specified"
How do I fix this??
Kind regards, Datius Blaszijk

Fw: Contour plot
...uare matrix with all the
data. But the question now is;
- can the contourplot not interpolate the missing values
or alternatively
- I have fit a model to the z data (z = 100 + 0.5x + 0.5y). How can I make
from this model a "square" matrix z to make a contour plot?
Kind regards, Darius Blaszijk
