The wk package doesn't operate on CRS objects, but does propagate them through subsetting and concatenation. A CRS object can be any R object, and x can be any object whose 'crs' attribute carries a CRS. These functions are S3 generics to keep them from being used on objects that do not use this system of CRS propagation.

wk_crs(x)

# S3 method for wk_vctr
wk_crs(x)

# S3 method for wk_rcrd
wk_crs(x)

wk_crs(x) <- value

wk_set_crs(x, crs)

wk_crs_output(...)

Arguments

x, ...

Objects whose "crs" attribute is used to carry a CRS.
