# Continuous Confidence Interval Plots using t-Distribution

Provides an extension to 'ggplot2' (Wickham, 2016, ) for creating two
types of continuous confidence interval plots (Violin CI and Gradient CI plots), typically for the sample mean.
These plots contain multiple user-defined confidence areas with varying colours,
defined by the underlying t-distribution used to compute standard confidence intervals for
the mean of the normal distribution when the variance is unknown.
Two types of plots are available, a gradient plot with rectangular areas, and a violin plot where the
shape (horizontal width) is defined by the probability density function of the t-distribution.
