densityGridDS {dsBase} | R Documentation |
Generates a density grid that can then be used for heatmap or countour plots.
densityGridDS( xvect, yvect, limits = FALSE, x.min = NULL, x.max = NULL, y.min = NULL, y.max = NULL, numints = 20 )
xvect |
a numerical vector |
yvect |
a numerical vector |
limits |
a logical expression for whether or not limits of the density grid are defined by
a user. If |
x.min |
a minimum value for the x axis of the grid density object, if needed |
x.max |
a maximum value for the x axis of the grid density object, if needed |
y.min |
a minimum value for the y axis of the grid density object, if needed |
y.max |
a maximum value for the y axis of the grid density object, if needed |
numints |
a number of intervals for the grid density object, by default is 20 |
Invalid cells (cells with count < to the set filter value for the minimum allowed counts in table cells) are turn to 0.
