In spsanderson/LICHospitalR: Hospital Data Analysis Workflow Tools

Description

Gives the optimal bindwidth for a histogram given a data set, it's value and the desired amoutn of bins

Usage

opt_bin(.data, .value_col, .iters = 30)

Arguments

.data	The data set in question
.value_col	The column that holds the values
.iters	How many times the cost function loop should run
