R: quantiles

quantile.ff {ffbase} | R Documentation

## quantiles

### 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

`x` | `ff` vector
`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.
`...` | currently not used
