[R] Using axis limits with plot3D

Hi Scott, The trick is to postpone plotting (plot = FALSE) and then do plotdev() with the required limits: library(plot3D) x <- z <- seq(-4, 4, by=0.2) y <- seq(-6, 6, by=0.2) M <- mesh(x,y,z) R <- with(M, sqrt(x^2 + y^2 +z^2)) p <- sin(2*R)/(R+1e-3) x.limits <- c(-2, 2) y.limits <- c(-2, 2) sli

[R] ode() tries to allocate an absurd amount of memory

Thomas, It is a limitation of the function you are using. The method "vode" is an implicit method, meaning that it has to create and invert a matrix of the size = number of variables ^2. In your case, this is a full matrix of 33000 rows and columns. If your ODE is easy to solve, you might try t
