I'm trying to produce a 3d plot with wireframe function or any other
package in R . I want to show how z changes in response to x and y. But I
fail to produce a 3d surfaceplot with a wireframe command which gives me
different error messages.
## Generate data
x <- seq(from=0, to=100,by=1)
y <- seq(from=0, to=20,by=1)
df <- expand.grid(x=x,y=y)
df$z<-1/(1+(exp(-(-1.42+0.04*df$x+0.4*df$y))))
The command that I used is this one
require(lattice)
wireframe(df ~ x * y, df, shade = TRUE, aspect = c(1, 1),light.source =
c(10,10,10))
Any help and suggestion is highly appreciated!
