cloud() works but wireframe() is blank
...<-rnorm(100)
> z<-runif(100)
> temp <-data.frame(x,y,z)
> wireframe(x~y*z,temp)
> cloud(x~y*z,temp)
There is something funny about the way wireframe treats a data frame object
created using "data.frame" vs. using "expand.grid". For instance, this
works:
reggrid <- expand.grid(u=1:10,v=1:10)
reggrid$z <- runif(100)
reggrid <- data.frame(reggrid)
is.data.frame(reggrid)
wireframe(z~u*v,reggrid,scales=list(arrows=FALSE),drape=TRUE,colorkey=TRUE)
but this does not:
u <- c(1:100)
v <- mat.or.vec(100,1)
ij=0
for(i in 1:10)
{
for(j in 1:10)...
