plot_fitted: Plot the Bayesian curve fitted values
In drkowal/dfosr: Dynamic Function-on-Scalars Regression

Plot the curve posterior means with posterior credible intervals (pointwise and joint), the observed data, and true curves (if known)

1 2	plot_fitted(y, mu, postY, y_true = NULL, t01 = NULL, include_joint_bands = FALSE)

`y`	the `T x 1` vector of time series observations
`mu`	the `T x 1` vector of fitted values, i.e., posterior expectation of the mean
`postY`	the `nsims x T` matrix of posterior draws from which to compute intervals
`y_true`	the `T x 1` vector of points along the true curve
`t01`	the observation points; if NULL, assume `T` equally spaced points from 0 to 1
`include_joint_bands`	logical; if TRUE, compute simultaneous credible bands
