Hi,
I’m starting to work my way through “Machine Learning With R” by Brett Lantz.

I’ve downloaded and installed R and the R Console comes up fine.
Whenever I use the install.packages command, regardless of the package I get

You probably want function persp3d() in package rgl. You have to define the
formula as a function and specify the limits correctly, but you were close:

This looks like data for a morphometrics analysis so you should know about
package geomorph. Data like yours is often stored as a three dimensional array
so we switch to that format and then use the two.d.array() function in package
geomorph:
Assuming your dataset is called dat:

R has several options for projecting a 3 dimensional plot onto a 2
dimensional plane and plotting the result. Which is best depends on
what you want.
You mention a function "plot3d" but not which package it comes from.

Great. missing is what I was looking for, and it seems to also work

Dear All, I´m running a glm with poisson errors and have a doubt when
ploting the predicted values. One of my variables has a positive slope in
the summary output, but when I plot the predicted values on the original
plot it draws a line with negative slope. I appreciate your comments on
this and a

paste() and paste0() will work here. paste0() defaults to "" between character
vector elements and paste() defaults to " " (single blank character) between

Hi,
I've been led to believe that in R it is possible to produce a 3d
analytical plot of a function. I've been pointed in the direction of
plot3d(), so the command is something like
plot3d(x^2+y^2,(x,-3,3),(y,-3,3)). And a smart person out there is going to
tell me where this syntax comes from
