Computes the inertia tensor of a molecular system from atomic coordinates and masses.
Usage
inertia(...)
"inertia"(x, m, ...)
"inertia"(x, m = NULL, ...)
"inertia"(x, m = NULL, ...)
Arguments
x
an R object containing atomic coordinates.
m
a numeric vector containing atomic masses.
...
further arguments passed to or from other methods.
Value
Details
inertia is a generic function to compute the inertia tensor of a molecular system. For object of class ‘coords’ both atomic coordinates and masses have to be speifyed. For object of class ‘atoms’ the masses are determined from the elename component of the object (see toSymbols and masses). For object of class ‘pdb’ the atoms component is used.
