dg_closest_res | R Documentation |
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.
dg_closest_res( dggs, col, val, round = "nearest", show_info = TRUE, metric = TRUE )
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) |
A number representing the grid resolution
library(dggridR) dggs <- dgconstruct(res=20) res <- dg_closest_res(dggs,'area_km',1) dggs <- dgsetres(dggs,res)
