gravmagsubs-package | R Documentation |
The package gravmagsubs
provides tools for computing the gravitational and magnetic anomalies generated by 3-D vertical rectangular prisms at specific observation points. The package consists of two functions:
rectprismgrav
: Computes the gravitational attraction of 3-D right rectangular prisms.
rectprismmag
: Computes the magnetic effect of 3-D right rectangular prisms.
Each function can compute the total anomaly of a series of N
prisms at M
observation points.
Each function also has a logical flag bycell
(default FALSE
). If bycell=TRUE
, the function returns the contribution from each individual prism.
