checkintrfr  R Documentation 
r f_r(r)
This function is auxiliary to polyCub.iso
.
The (analytical) integral of r f_r(r)
from 0 to R
is checked
against a numeric approximation using integrate
for various
values of the upper bound R
. A warning is issued if inconsistencies
are found.
checkintrfr(intrfr, f, ..., center, control = list(), rs = numeric(0L),
tolerance = control$rel.tol)
intrfr 
a 
f 
a twodimensional realvalued function. As its first argument it must take a coordinate matrix, i.e., a numeric matrix with two columns, and it must return a numeric vector of length the number of coordinates. 
... 
further arguments for 
center 
numeric vector of length 2, the center of isotropy. 
control 
list of arguments passed to 
rs 
numeric vector of upper bounds for which to check the validity of

tolerance 
of 
The intrfr
function. If it was not supplied, its quadrature
version using integrate
is returned.
