Access a distribution's probability density function (pdf).
eval_density(distribution, at)enframe_density(..., at, arg_name = ".arg", fn_prefix = "density", sep = "_")
The evaluated representation in vector form (for eval_)
with length matching the length of at, and data frame
or tibble form (for enframe_) with number of rows matching the
length of at. The at input occupies the first column,
named .arg by default, or the specification in arg_name;
the evaluated representations for each distribution in ...
go in the subsequent columns (one column per distribution). For a
single distribution, this column is named according to the
representation by default (cdf, survival, quantile, etc.),
or the value in fn_prefix. For multiple distributions, unnamed
distributions are auto-named, and columns are named
<fn_prefix><sep><distribution_name> (e.g., cdf_distribution1).
A distribution, or possibly multiple
distributions in the case of ....
Vector of values to evaluate the representation at.
For enframe_, name of the column containing
the function arguments. Length 1 character vector.
For enframe_, name of the function to
appear in the column(s). Length 1 character vector.
When enframe'ing more than one distribution, the
character that will be separating the fn_name and the distribution name.
Length 1 character vector.
