Compute the symbolic variance.
var(x, ...)# S3 method for default
var(x, y = NULL, na.rm = FALSE, use, ...)
# S3 method for symbolic_interval
var(x, method = c("centers", "interval", "billard"), na.rm = FALSE, ...)
# S3 method for symbolic_tbl
var(x, ...)
A symbolic interval.
As in R median function.
NULL (default) or a vector, matrix or data frame with compatible dimensions to x. The default is equivalent to y = x (but more efficient).
logical. Should missing values be removed?
an optional character string giving a method for computing covariances in the presence of missing values. This must be (an abbreviation of) one of the strings 'everything', 'all.obs', 'complete.obs', 'na.or.complete', or 'pairwise.complete.obs'.
The method to be use.
