dg_closest_res {dggridR} | R Documentation |
Determine an appropriate grid resolution based on input data.
Description
This is a generic function that is used to determine an appropriate resolution given an area, cell spacing, or correlated length scale. It does so by extracting the appropriate length/area column and searching it for a value close to the input.
Usage
dg_closest_res(
dggs,
col,
val,
round = "nearest",
show_info = TRUE,
metric = TRUE
)
Arguments
dggs |
A dggs object from dgconstruct() |
col |
Column in which to search for a close value. Should be: area_km, spacing_km, or cls_km. |
val |
The value to search for |
round |
What direction to search in. Must be nearest, up, or down. |
show_info |
Print the area, spacing, and CLS of the chosen resolution. |
metric |
Whether input and output should be in metric (TRUE) or imperial (FALSE) |
Value
A number representing the grid resolution
Examples
library(dggridR)
dggs <- dgconstruct(res=20)
res <- dg_closest_res(dggs,'area_km',1)
dggs <- dgsetres(dggs,res)
