Oyster_subincr_phases {shelltrace} | R Documentation |
Calculates proportion of phases in each sub-increment
Description
Function that takes the matrix of sub-increment positions and the matrix of phases and calculates the amount of pixels of each phase that is contained in each sub-increment based on pixelsize and phase characteristics. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>
Usage
Oyster_subincr_phases(IncG, phasemat, pixelsize, phases)
Arguments
IncG |
Matrix of X- and Y-coordinates of all interpolated sub-increments |
phasemat |
matrix of phases of each pixel sorted by X- and Y-coordinate of the pixel |
pixelsize |
size of pixels in the phase map in millimeter |
phases |
Matrix containing colour and trace element data of the phases in the XRF phase map |
Details
For every sub-increment, all pixels that cover area in the sub-increment are identified based on the pixel size of the phase map and the X- and Y-positions of the sub-increments. The amount of pixels of each phase in the sub-increment is saved in a new matrix of phases per sub-increment
Value
A matrix of the amount of pixels for each phase found in every sub-increment
phase_mat |
Matrix of amounts of pixels of each phase per sub-increment |
