cv.Rd
Compute the coefficient of variation (expressed as a percentage). If there is only a single value, sd
is NA
and cv
returns NA
if aszero=FALSE
(the default). However, if (aszero=TRUE
), cv
returns 0
.
# S4 method for ANY
cv(x, ..., aszero=FALSE, na.rm = FALSE)
# S4 method for Raster
cv(x, ..., aszero=FALSE, na.rm = FALSE)
A vector of numbers (typically integers for modal), or a Raster* object
additional (vectors of) numbers, or Raster objects
logical. If TRUE
, a zero is returned (rather than an NA) if the cv of single value is computed
Remove (ignore) NA values
vector or RasterLayer
