composition {coda.base} | R Documentation |
Calculate a composition from coordinates with respect a given basis
composition(H, basis = NULL, label = "x", sparse_basis = FALSE)
H |
coordinates of a composition. Either a matrix, a data.frame or a vector |
basis |
basis used to calculate the coordinates |
label |
name given to the coordinates |
sparse_basis |
Is the given matrix basis sparse? If TRUE calculation are carried taking into an account sparsity (default 'FALSE') |
coordinates with respect the given basis
See functions ilr_basis
, alr_basis
,
clr_basis
, sbp_basis
to define different compositional basis.
See function coordinates
to obtain details on how to calculate
coordinates of a given composition.
