plot_curve: Plot a curve given posterior samples
In drkowal/dfosr: Dynamic Function-on-Scalars Regression

Plot the posterior mean, simultaneous and pointwise 95% credible bands for a curve given draws from the posterior distribution

1 2	plot_curve(post_f, tau = NULL, alpha = 0.05, include_joint = TRUE, main = "Posterior Mean and Credible Bands", ylim = NULL)

`post_f`	`Ns x m` matrix of `Ns` posterior simulations of the curve at `m` points
`tau`	`m x 1` vector of observation points
`alpha`	confidence level for the bands
`include_joint`	logical; if TRUE, include joint bands (as well as pointwise)
`main`	title text (optional)
`ylim`	range of y-axis (optional)
