int.simpson: Simpson integration

Description

Computes the integral of fdataobj$data with respect to fdataobj$argvals using simpson or trapezoid rule integration.

Usage

int.simpson(fdataobj,equi=TRUE,method="TRAPZ")

Arguments

fdataobj

fdata objtect.

equi

=TRUE, the observed points on each curve are equally spaced (by default).

method

Method for numerical integration, see details.

Details

If method="CSR", composite Simpson's rule integration is used. If method="ESR", extended Simpson's rule integration is used. If method="TRAPZ", Trapezoid rule integration is used.

Examples

# NOT RUN {
x<-seq(0,2*pi,length=1001)
fx<-fdata(sin(x)/sqrt(pi),x)
fx0<-fdata(rep(0,length(x)),x)
int.simpson(fx0)
int.simpson(fx)
# }
