pdf.Cauchy: Evaluate the probability mass function of a Cauchy distribution

Description

Evaluate the probability mass function of a Cauchy distribution

Usage

# S3 method for Cauchy
pdf(d, x, drop = TRUE, ...)
# S3 method for Cauchy
log_pdf(d, x, drop = TRUE, ...)

Value

In case of a single distribution object, either a numeric vector of length probs (if drop = TRUE, default) or a matrix with length(x) columns (if drop = FALSE). In case of a vectorized distribution object, a matrix with length(x) columns containing all possible combinations.

Arguments

d

A Cauchy object created by a call to Cauchy().

x

A vector of elements whose probabilities you would like to determine given the distribution d.

drop

logical. Should the result be simplified to a vector if possible?

...

Arguments to be passed to dcauchy. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.
