This function is a high level interface to the plotrix 'color.legend' function. It makes reasonable assumptions on the plottin window to place the colour and allows the user to specify log spacing for the colour gradient and labels, as well as add a title.

Functions to make pretty axes (major and minor) on scientific plots. Particularly effort is made on producing nice log plot outputs. The core function produces pretty axis labelling in a number of circumstances that are often used in scientific plotting. There is a higher level interface to a generic plot function that will usually produce nice plots, even without much though on the users part.
This function generates nicely arranged axes for scientific plots, including minor tick marks. It supports log settings and can unclog axes that have been logged inline by the user. When the dynamic range is 50 or less and axis is logged, axis range factors of 10 times 1, 2 and 5 are used instead of powers of 10 alone.
A very high level (minimal options) MCMC chain triangle plot function. The default is deliberately spartan in terms of options, but the result should be a clear set of covariance plots that should give quick insight into the stationary sampling quality of a set of MCMC posterior chains.
magimage is a level replacement for base image with hooks into magaxis for the tick marks and magmap for the image scaling. The default behavious is a bit different to base (e.g. x/y scales are automatically the number of pixels in the image matrix). magimageRGB is similar, but is for the creation colour images where the user can provide R G B input matrix chanels (or similar).
Utilises pretty for the major-tick locations, but makes prettier decisions if log axes are being used. Translates the default text into nicely formatted expressions- this is particularly successful when axes are logged and exponents are used since formats like 1e5 should not be used in scientific academic journals.
This function allows the use to remap a vector of values onto a different system. For instance you might have values stretching from -10 to 100 which you want mapped from 0 to 2/3 so you can then sue the output as an input for point colour or size. It allows clipping of values, rejection of bad values, and log stretching.
High level functions to add great circles and thick bands on projections plots. In astronomy these are popular for indicating regions of exclusion surrounding the ecliptic or the Milky-Way plane. Also simple functions to add either the MW bluge to the current projection (magMW) or the sun on a given date (magsun).
