Sets the grid size for the Pswarm algorithm
Description
Automatically sets the size of the grid, formula see [Thrun, 2018, p. 93-94].
Usage
setGridSize(InputDistances,minp=0.01,maxp=0.99,alpha=4)
Arguments
InputDistances |
[1:n,1:n] symmetric matrix of input distances |
minp |
default value: 0.01,see |
maxp |
default value: 0.99, see |
alpha |
Do not change! Intern parameter, Only if Java Version of Pswarm instead of C++ version is used. |
Details
grid is set such that minimum and maximum distances can be shown on the grid
Value
LC=c(Lines,Columns) size of the grid for Pswarm
