fm_CRSargs: Show expanded CRS arguments

In fmesher: Triangle Meshes and Related Geometry Tools

Show expanded CRS arguments

Description

Wrappers for sp::CRS and inla.CRS objects to handle the coordinate reference system argument string. These methods should no longer be used with PROJ6/rgdal3; see fm_wkt() and fm_proj4string() for a new approach.

Usage

fm_CRS_as_list(x, ...)

fm_list_as_CRS(x, ...)

fm_CRSargs(x, ...)

fm_list_as_CRSargs(x, ...)

fm_CRSargs_as_list(x, ...)

Arguments

x	An sp::CRS or inla.CRS object (for fm_CRSargs and fm_CRS_as_list), a character string (for fm_CRSargs_as_list), or a list (for fm_list_as_CRS and fm_list_as_CRSargs).
...	Additional arguments passed on to other methods.

Value

For fm_CRSargs and fm_list_as_CRSargs, a character string with PROJ.4 arguments.

For fm_CRS_as_list and fm_CRSargs_as_list, a list of name/value pairs.

For fm_list_as_CRS, a CRS or inla.CRS object.

For fm_list_as_CRSargs(), a CRS proj4 string for name=value pair list

For fm_CRSargs_as_list(), a list of name=value pairs from CRS proj4 string

crs1 <- fm_list_as_CRS(lst)
lst$a <- 2
crs2 <- fm_CRS(p4s, args = lst)
print(fm_proj4string(crs0))
print(fm_proj4string(crs1))
print(fm_proj4string(crs2))
