Create vector based on roughly equally sized groups

Description

Create vector based on roughly equally sized groups

Usage

ntiles(
  x,
  n = 3,
  format = c("rank", "interval", "mean", "median", "center", "left", "right"),
  digits = 3
)

Arguments

x	a numeric vector
n	(approximate) number of quantiles
format	a specification of desired output format.
digits	desired number of digits for labeling of factors.

Value

a vector. The type of vector will depend on format.

Examples

if (require(mosaicData)) {
tally( ~ ntiles(age, 4), data=HELPrct)
tally( ~ ntiles(age, 4, format="center"), data=HELPrct)
tally( ~ ntiles(age, 4, format="interval"), data=HELPrct)
tally( ~ ntiles(age, 4, format="left"), data=HELPrct)
tally( ~ ntiles(age, 4, format="right"), data=HELPrct)
tally( ~ ntiles(age, 4, format="mean"), data=HELPrct)
tally( ~ ntiles(age, 4, format="median"), data=HELPrct)
bwplot( i2 ~ ntiles(age, n=5, format="interval"), data=HELPrct)
}
