Description
The function quantile produces quantiles corresponding to
the given probabilities. The smallest observation
corresponds to a probability of 0 and the largest to a
probability of 1. Current implementation doesn't use the
type
parameter of quantile
. For
large ff
vectors the difference between the types
is (very) small. If x
has been
ffordered
, quantile is fast, otherwise it
is $n log(n)$.Usage
## S3 method for class 'ff':
quantile(x, probs = seq(0, 1, 0.25),
na.rm = FALSE, names = TRUE, ...)
Arguments
probs
numeric vector of probabilities with values
in [0,1].
na.rm
logical; if true, any NA and NaN's are
removed from x before the quantiles are computed.
names
logical; if true, the result has a names
attribute. Set to FALSE for speedup with many probs.
