GraphicParameters: Loads graphic parameters

In stevenlecomber/Rgeoprofile-1.1.0: Generates geograpic profiles from point pattern data

Description

Sets the parameters for the Google maps and the plotting area of the surfaces produced by the model.

Usage

GraphicParameters(Guardrail = 0.05, nring = 20, transp = 0.4, gridsize = 640, gridsize2 = 300, MapType = "roadmap", Location = getwd(), pointcol = "black")

Arguments

Guardrail	Sets the extent of the guardrail around the points. This will fix the size of the profile created and printed to the map. Defaults to 10% (0.05 in each direction), must be a postive number.
nring	The number of rings of the contours and raster image plots produced by PlotGP and CreateMaps, defaults to 20. Generally looks good in the 10-30 region.
transp	The transparasncy of the raster image produced by PlotGP and CreateMaps, defaults to 0.4. Must be between 0 and 1, with 0 being completely transparent and 1 being completely opaque .
gridsize	The gridszise of the Rgoogle maps, fed to the function GetMap. Google has a maximum gridsize of 640 which is the default, can be betwene 0 and 640.
gridsize2	The gridsize of the geoprofile and subequent raster images produced by PlotGP and CreateMaps, defaults to 300. Note, increasing this will increase the computational time, potentially signifcantly. Recommend 150-450, for very high reslution profiles it can be increased, but building the profile in ThinandAnlasye will take substantially more time.
MapType	The Google map type of the map produced. Fed to GetMap, defaults to "roadmap" but can be any one of: "roadmap","mobile","satellite", "terrain" or"hybrid".
Location	The filepath that Google maps, surfaces and outputs will be saved. Defaults to the working directory. Needs to be working for map generation to take place, check your computer has given R access permissions.
pointcol	The colour of the points produced by PlotGP and CreateMaps, defaults to "black".

Details

This function loads in and sets all of the graphic parameters used in the resulting map generation, model and plotting. The Location must be set to a useable filepath. The deafults will produce clear plots, nring and MapType can be manually edited in the console at a later point when producing desiered surfaces using PlotGP.
