df_transform

R Documentation

Transform projection of data.frame

Description

Change the projection of x and y values (spatial coordinates) of a data.frame, make sure your data only includes x,y and z and no additional categorical variables

Usage

df_transform(data, coords, crs.in, crs.out)

Arguments

`data`	data.frame object
`coords`	vector of the two coordinate column names
`crs.in`	original projection of data.frame, standard is WGS1984.
`crs.out`	output projection of data.frame, which is returned.

Details

df_transform internally converts the data.frame into a spatial object, than transforms the projection of the data and converts the final spatial object back into a data.frme.

Value

A data.frame

Examples

data(meuse, package="sp")
meuse <- df_transform(meuse, 
                      crs.in=sp::CRS("+init=epsg:28992"), 
                      crs.out=sp::CRS("+init=epsg:4326"))
