plotMultipleHistograms: Plot multiple histograms in the same plot
In JosephCrispell/plotteR: A collection of functions to help with base R plotting

This function uses the hist function to plot multiple distributions in the same plot

1	plotMultipleHistograms(distributions, nBins = 10, colours, ...)

`distributions`	A list containing multiple distributions - each represented as a numeric vector
`nBins`	The number of bins to be used in the plot. Defaults to 10
`colours`	A vector of length `length(distributions)` containing the colour of each distribution plotted
`...`	Arguments to be passed to `plot()` function

# Create two random samples from a normal distribution
distributions <- list(rnorm(500, mean=5, sd=0.5), 
                      rnorm(500, mean=8, sd=5), 
                      rnorm(500, mean=20, sd=2))

# Plot overlapping histograms
plotMultipleHistograms(distributions, nBins=20, colours=c(rgb(1,0,0, 0.5), rgb(0,0,1, 0.5), rgb(0,1,0, 0.5)), las=1)
