Extract a manifold definition string, or a logical for matching
manifold type
Usage
fm_manifold(x, type = NULL)
fm_manifold_type(x)
fm_manifold_dim(x)
Arguments
- x
An object with manifold information, or a character string
- type
character; if NULL (the default), returns the manifold definition string.
If character, returns TRUE if the manifold type of x matches at least
one of the character vector elements.
Value
fm_manifold(): Either logical (matching manifold type yes/no),
or character (the stored manifold, when is.null(type) is TRUE)
fm_manifold_type(): character or NULL; "M", "R", "S", or "T"
fm_manifold_dim(): integer or NULL
Examples
fm_manifold(fmexample$mesh)
#> [1] "R2"
fm_manifold_type(fmexample$mesh)
#> [1] "R"
fm_manifold_dim(fmexample$mesh)
#> [1] 2
