Hi all,I am having some difficulties in vectorizing the integrate function. Let
me explain with an example.
a <- 10; b <- 3; c <- 4
f <- function(x) {exp(-a*x^3-b*x^2-c*x)}
integrate(f,0,Inf) # works fine
My difficulties start when I want to vectorize.
# attempts to vectorize fail
a <- seq(from=

Hi all,On looking at the source code for the integrate function, I find that it
has the following call:
wk <- .External(C_call_dqagi, ff, rho = environment(),
as.double(bound), inf, as.double(abs.tol), as.double(rel.tol),
limit = limit)How do I access the source code for
d command?
That's a material property, so you can just put it in as part of the
dots. For the meshes, it would go into the shade3d() call in the same
way, or the material argument to qmesh3d.

Hi,I want to plot a surface joining a circle on a plane with another circle (a
little offset w.r.t. the first one) on a parallel plane. This is a very
simplified version of my problem.
I will explain with the following code :
# First, I plot the two circlesorig1 <- 0.4;radius1=0.3;theta <-
