Density, distribution function, quantile function and random
generation for the Cauchy distribution with location parameter
`location`

and scale parameter `scale`

.

```
dcauchy(x, location = 0, scale = 1, log = FALSE)
pcauchy(q, location = 0, scale = 1, lower.tail = TRUE, log.p = FALSE)
qcauchy(p, location = 0, scale = 1, lower.tail = TRUE, log.p = FALSE)
rcauchy(n, location = 0, scale = 1)
```

x, q

vector of quantiles.

p

vector of probabilities.

n

number of observations. If `length(n) > 1`

, the length
is taken to be the number required.

location, scale

location and scale parameters.

log, log.p

logical; if TRUE, probabilities p are given as log(p).

lower.tail

logical; if TRUE (default), probabilities are \(P[X \le x]\), otherwise, \(P[X > x]\).

`dcauchy`

, `pcauchy`

, and `qcauchy`

are respectively
the density, distribution function and quantile function of the Cauchy
distribution. `rcauchy`

generates random deviates from the
Cauchy.

The length of the result is determined by `n`

for
`rcauchy`

, and is the maximum of the lengths of the
numerical arguments for the other functions.

The numerical arguments other than `n`

are recycled to the
length of the result. Only the first elements of the logical
arguments are used.

If `location`

or `scale`

are not specified, they assume
the default values of `0`

and `1`

respectively.

The Cauchy distribution with location \(l\) and scale \(s\) has density $$f(x) = \frac{1}{\pi s} \left( 1 + \left(\frac{x - l}{s}\right)^2 \right)^{-1}% $$ for all \(x\).
