maps2dataframe: maps2dataframe

In geodetector: Stratified Heterogeneity Measure, Dominant Driving Force Detection, Interaction Relationship Investigation

Description

This function transforms the information of varialbles from shipfiles to dataframe.

Usage

maps2dataframe(y_shp, x_shp_n, namescolomn)

Arguments

y_shp	The shipfile( polygons or points) containing explained varialble in its attribute table.
x_shp_n	Shipfiles( polygons or points) containing explained varialble in their attribute tables.
namescolomn	Field names which represent explained variable and explanatory variables, respectively. The order correspond with y_shp and x_shp_n.

Value

dataframe transformed from shape files. If input data is shapefile format, the function named geoDetector can be used to transform from shapefile map to table format. Please note that, these shapefile layers should have the same projected coordinate system.

Examples

library(maptools)

data(DiseaseData_shp)
data(SoilType_shp)
data(Watershed_shp)
data(Elevation_shp)
CollectData2<-maps2dataframe(DiseaseData_shp,c(SoilType_shp, Watershed_shp,
                             Elevation_shp),namescolomn= c('incidence',
                             'soiltype', 'watershed', 'elevation'))
