R Documentation

Analyze changes and rates of boundary movement

Description

The function requires an ESRI Shapefile with point data representing historical boundary positions along a transect. The shapefile must be properly formatted and contain the proper fields. See links below for additional information. The function will generate data tables and graphics containing the results of analysis statics given user specified parameters.

Usage

ambur.analysis(userinput1 = "first", userinput2 = 95, 
userinput3 = "m", userinput4 = "", userinput5 = 1, 
userinput6 = "all", userinput7 = "basic",  userinput8 = "yr")

Arguments

`userinput1`	Use first or last intersections along the transect. DEFAULT = "first"
`userinput2`	Confidence interval. DEFAULT = 95
`userinput3`	Map units. DEFAULT = "m" for meters (mainly used for labeling graphic axes)
`userinput4`	Name of the analysis. DEFAULT = nothing. (will add a name to the time-stamped folder where results are stored
`userinput5`	Start transect. DEFAULT = 1
`userinput6`	End transect. DEFAULT = all
`userinput7`	Basic or advanced analysis. DEFAULT = basic
`userinput8`	Time units for rates. DEFAULT = "yr" (options = "day", "hr", "min", "sec")

Details

If an "advanced" analysis is specified, more statics are generated and included in the output data tables. However, this will increase the processing time.

Value

Creates a date and time stamped folder inside a parent folder named "AMBUR_results", located in the same folder as the shapefile. The folder contains all of the output data and graphics.
