Internal function to translate and rotate a secondary structure plot

Description

Given a coordinate file, a point, and an angle in radians transformFold rotates the fold around the given point the given number of radians.

Usage

transformFold(dat, x0, y0, ang)

Arguments

dat	Coordinate file containing multiple RNA folds
x0	x coordinate of center of rotation
y0	y coordinate of center of rotation
ang	angle of rotation in radians

Value

dat frame containing the rotated coordinates
