pdd
(Package: ocean) :
Plot the density of x and y on grid.
Plots the distribution of x and y on grid. This function follows the method described in Simons et al 2013: first vertically integrating the data, then dividing by the number of particles spawned, and finally applying an Gaussian blur filter. The coordinates should be passed in as x,y in meters, then are inverse projected into lat/long using the PROJ.4 library.
fvcom.grid provides a represenation of the unstructured triangular sigma grid used by the Finite Volume Community Ocean Model (FVCOM). As a disclaimer, please note that the author of this package is a user of FVCOM, but is not affiliated with its development.
interp
(Package: ocean) :
Convert a single scalar or node based quantity to element based.
The length of x determines how it will be treated. If x has length 1, it is returned as a single color. If the length of x is the number of nodes in the grid, its value for each element is calculated as the average of the value at the adjoining nodes. If the length of x is the number of elements in the grid, it is returned as is. Any other values throw an error.
Given a vector of data, this function plots the data as a heatmap on an unstructured grid. The length of the data vector must be as long as either the number nodes in the grid or the number of elements in the grid. The grid is currently stored as a data.frame, but will be converted to an S4 object in the future.
