This function generate a check layout in a retangular grid. the check and partial replicated entries are spread by blocksdesign library
1 | p_rep_check_by_density(n.row, n.col, check.density = 0.05, by.density)
|
n.row |
The row of a retangular grid |
n.col |
The column of a retangular grid |
check.density |
The density of the check |
by.density |
The total density of check and p_rep, MUST be a even decimal number after substract the check.density |
A dataframe will return: row.var=row, col.var=col, check=0, single rep; 1, check; else, partial replicated entries
1 2 3 4 | # To produce a 20 by 20 field with check distributed by density=0.35
nr = 20; nc = 20
example.tmp = p_rep_check_by_density(nr, nc, by.density=.35)
fields::quilt.plot(example.tmp, nx=nr, ny=nc)
