In amyarneson/crasch: Construct Mapping with Rasch

Create a histogram of person estimates.

1 2	pers.hist(results, dim = NULL, palette = "BASS", normal = FALSE, writeout = FALSE, imageType = "pdf", fileSuffix = NULL, ...)

`results`	The output from a run of `craschR`. (link?)
`dim`	A numeric vector that specifies for which dimension(s) to create graphic/tables. If `NULL`, output and graphics for each dimension will be produced.
`palette`	The color scheme for the histogram. Can be "BASS or any RColorBrewer palette name (the first 2 colors of the 3-color palette will be used). Can also specify a vector with 2 colors in any R-supported form; the first color is for the bars and the second is for the normal curve.
`normal`	A logical incating whether to include the normal curve overlaid on the plot. The estimated mean and variance define the curve.
`writeout`	A logical indicating whether the graph should be written to your working directory as your indicated `imageType`. If `TRUE`, the file name will begin `pershist` and will include an index (if more than one graph is produced) and the `fileSuffix` if provided.
`imageType`	A character string indicating the format for graphics (if `writeout = TRUE`). Supported types: `c("pdf","svg","jpeg","bmp","tiff","png")`.
`fileSuffix`	A character string that will be affixed to the end of each file name (if `writeout = TRUE`). Use this if you are conducting multiple analyses in the same working directory and do not wish for your existing files to be overwritten.
`...`	Additional arguments to be passed to `hist` function.
