Usage

fm_detect_manifold(x)

fm_crs_detect_manifold(x)

# S3 method for class 'crs'
fm_detect_manifold(x)

# S3 method for class 'CRS'
fm_detect_manifold(x)

# S3 method for class 'numeric'
fm_detect_manifold(x)

# S3 method for class 'matrix'
fm_detect_manifold(x)

# S3 method for class 'fm_mesh_2d'
fm_detect_manifold(x)

Arguments

x

Object to investigate

Value

A string containing the detected manifold classification

Functions

• fm_crs_detect_manifold(): Detect if a crs is on "R2" or "S2" (if fm_crs_is_geocent(crs) is TRUE). Returns NA_character_ if the crs is NULL or NA.

Examples

fm_detect_manifold(1:4)
#> [1] "R1"
fm_detect_manifold(rbind(c(1, 0, 0), c(0, 1, 0), c(1, 1, 0)))
#> [1] "R2"
fm_detect_manifold(rbind(c(1, 0, 0), c(0, 1, 0), c(0, 0, 1)))
#> [1] "S2"
