In lilyacb/quakeTri: What the Package Does (One Line, Title Case)

Description

geo_circle_intersections: use points on two circles (can be created with destPoint) to approximate their intersection points by finding points on each circle that are close together (using distGeo for accurate distance). This functino uses hclust to separate out the two intersections by geographical distance.

Usage

geo_circle_intersections(circle1, circle2, intersection_name)

Arguments

circle1	dataframe of points on a circle with cols (lon,lat)
circle2	dataframe of points on a circle with cols (lon,lat)
intersection_name	character string to label the intersection points

Value

a dataframe of cols (lon,lat) and 2 rows containing the 2 intersection points of the circles (as averages of all the points in a cluster), if they exist

Examples

Usage example
RLOK_ELIS_ints<-geo_circle_intersections(RLOK_circle,ELIS_circle,"RLOK_ELIS")
