3d plotting with cloud and wireframe
...in two variables to get a feel
for sensitivity to its parameters. I've run expand.grid to get made-up
vectors of the combinations of the two independent variables, and am trying
to plot the output of the dependent, M, against both the dependent in a 3d
space.
t <- 0:100
DBH <- 10:100
TxDBH<-expand.grid(t,DBH)
time<-TxDBH[,1]
dbh<-TxDBH[,2]
M <- 4000*(1-exp(-time*(1.104-(0.67*0.7)-0.163*log(dbh))^2))
I've tried wireframe(M~t|DBH, data=TxDBH)
wireframe(M~time|dbh, data=M)
wireframe(M~time|dbh)
also the above model specifications using cloud.
but
I get the foll...
