In amyarneson/crasch: Construct Mapping with Rasch

Returns and plots the mean location trajectories by category per item.

1 2	mn.traj(results, itemOrder = NULL, palette = "BASS", writeout = FALSE, imageType = "pdf", fileSuffix = NULL)

`results`	The output from a run of `craschR`. (link?)
`itemOrder`	A numeric vector that specifies which items from the output should be graphed. If `NULL`, all items will be graphed. Note that items scored on different dimensions will be graphed separately.
`palette`	A character string indicating the color scheme. Can be "BASS", any RColorBrewer palette or a vector containing any number of colors. The colors from each palette will be circulated through items.
`writeout`	A logical indicating whether the graphic should be written to to your working directory as your specified `imageType`. If `TRUE`, the file name will begin `meanTraj`, followed by an index for the dimension, 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.
