Write R code to create spatial relationships for determining where photos of a shoreline taken at an angle, intersect the shoreline.

Write R code to create spatial relationships for determining where photos of a shoreline taken at an angle, intersect the shoreline. Project overview Expected to be completed by Feb 28, 2020 Request details Requiring a piece of R code to assist with a citizen science project - MangroveWatch (not for profit) citizen science organisation. Project Description I have the following data; A table of points with coordinates and bearing/photo angle information (A) A line shapefile of a shoreline (B) A multipoint shapefile representing 10m interval points along shoreline - line B (C). I need; A csv table which contains for each point in A - determine the point in C which is closest to where a line (with a maximum distance) cast from Point A using the bearing in A intersects line B. Similar to ArcGIS Bearing-Distance to line tool, line intersect and Near. Data-files provided upon job acceptance. Deliverables R script that can be re-used producing csv output that includes the following information; Information in A Coordinates of Intersect and closest point C Error - the distance along the line between the line intersect and point C.
