Description
R Programming assignment. Instructions are in the assignment.
Requirements: # 1) The function should be named "hemisphereSummary" and have the following # parameters: # df : the input data frame (two columns) containing x and y values. # projargs: the character string of projection arguments, and should # default to "+proj=longlat +datum=WGS84". # 2) Within the function, you can (and should) load the libraries "sp" and # "foreach". No other libraries may be used. # 3) Within the function, register a sequential backend to foreach. # Hint: help(package="foreach") # 4) Before determining the hemispheres, the input data frame must be # converted to a SpatialPoints object (with the correct projection # arguments). # 5) The SpatialPoints object (not the input data frame) should be examined # one point at a time using a foreach loop. # 6) The loop should determine whether a point is in the northern or southern # hemisphere (we will count equatorial points as "north"), returned as # a factor "N" or "S". # 7) The loop should also determine whether a point is in the eastern or western # hemisphere (prime meridian points should be "east"), returned as a factor # "E" or "W". # 8) The final SpatialPointsDataFrame should have two attributes, "NShemisphere" # and "EWhemisphere", rownames should be set to NULL, and be returned from the function. # 9) Comment your code in at least 3 places. # 10) The code should be submitted tom Compass 2g as a single function with the filename: # LastName-FirstName-geog489-s20-assignment-05.R # and should have at the top:
