Compute the center (compositional mean) of a set of compositions

Unobserved values should be marked as NaN.

center(
  .data,
  weights = rep(1, nrow(.data)),
  method = "proj",
  in_scale = "linear",
  out_scale = "linear",
  denom = NULL,
  enframe = FALSE,
  components = FALSE
)

Arguments

.data	All-numeric data frame or matrix with taxa as columns.
weights	Sample (row) weights.
method	Method for computing the center: "proj", "gm", or "rss".
in_scale	"linear" or "log".
out_scale	"linear" or "log".
denom	Taxa to use in the denominator; if NULL, use all taxa.
enframe	Whether to return the bias estimate as a two-column tibble.
