Hello folks,
i'm a R beginner and i want to put in a same plot both contour lines
and persp plot.
For example,
fn<-function(x,y){sin(x)+2*y} #this looks like a corrugated tin roof
x<-seq(from=1,to=100,by=1) #generates a list of x values to sample
y<-seq(from=1,to=100,by=1) #generates a list of y values to sample
z<-outer(x,y,FUN=fn) #applies the funct. across the combos of x and y
persp(z) #plots without gridlines
contour(z) # for contour lines
i want this in a same plot.
Can anyone help me, i have no more idea to try this.
Thanks
