ramachandran: Ramachandran plot for two dihedral angles

Description

This plotting function divides a full rotation (360 degrees) into x- and y- bins and colors them according to the number of angle pairs that are provided in the input, a so-called Ramachandran plot.

Usage

ramachandran( dihedrals, xBins = 150, yBins = 150, heatFun = "norm",  structureAreas = c(), plotType = "sparse", printLegend = FALSE, heatUnits = NA, plotContour = FALSE, barePlot = FALSE, ... )

Arguments

dihedrals

Matrix with angles (two columns).

xBins

Number of bins (default: 150) used to plot (on the x-axis).

yBins

Number of bins (default: 150) used to plot (on the y-axis).

heatFun

Function selector for calculation of the colour, possible are either:

• "norm" (default) for linear calculation, or
• "log" for logarithmic calculation.

structureAreas

List of secondary structure areas, by default there are no regions specified.

plotType

Type of plot to be used, either "sparse" (default) or "fancy". The latter is a 3D representation.

printLegend

Boolean (default: false) specifying, whether a heat lengend is to be plotted or not.

heatUnits

String, containing a the unit of heat.

plotContour

Boolean (default: false) specifying, whether a contour should be plotted or no.

barePlot

Boolean, indicating whether the plot is to be made without any additional information.

...

Additional arguments (ellipsis).
