plotfits: Plot FITS images

Description

This function allows a FITS image to be converted into a PNG/X11 image, or output as a data array for use within a function. 3 colour RGB images may also be constructed by using multiple file inputs.

Usage

plotfits(input, hdu = 1, func = "atan", slide = c(0,0,0),  scale = c(500,300,100), locut = 0, hicut = pi/2, invert = FALSE,  method = 1, type = "x11", width = 5, height = 5, units = "in",  res = 300, cen = c(NA,NA), xdim = NA, ydim = NA,  file = "image.png")
