as_numeric_raster: As Numeric Raster
In jschap1/WSEw: River Geometry Package for Studying Water Surface Elevation-Width Relationships
Description
Usage
Arguments
Details
Value
Examples
Description
Converts a raster of factor values to the a raster of the corresponding numeric values.
Somewhat more efficient than get_depth_from_lutable, but can still take a long time for big rasters.
See raster::factor documentation.
Usage
1
as_numeric_raster(r, att)
Arguments
r
a raster with an attribute table
att
column of the attribute to extract
Details
Given a raster with data values coded in an attribute table, creates a raster directly composed of those values.
Loops over every entry in the raster; it is not very efficient.
Value
r2 raster of numeric values coded from the input raster
Examples
1
2
3
umesc <- raster("/Users/jschap/Box Sync/Margulis_Research_Group/Jacob/UMBB/Data/UMESC/bath_pool_21/bath_1999_p21")
umesc <- raster("bath_pool_21/bath_1999_p21")
depth <- as_numeric_raster(umesc, att = "DEPTH_M")
