n.row |
(Mandatory) The row of the field grid |
n.col |
(Mandatory) The column of the fields grid |
lon.lat |
(Optional) The distance calculation is based on earth distance (if TRUE), default is FALSE |
mile |
(Optional) The distance calculation is based on milage (if TRUE), default is FALSE |
density.choice |
(Mandatory) The density of the checks, a vector (range from 0 to 1) |
density.layout |
(Optional) The layout pattern of density, default are: 'diagonal', 'diagSet', 'random', 'equal_space', 'p_rep'. The diagSet is recommended over the diagonal at density from 0.01 to 0.35. |
h2 |
(Mandatory) The heritability of the simulated data, h2 = sigma_variety / (sigma_variety + sigma_env) |
sigma_env |
(Mandatory) The variance of environment, (equilievent of sill) |
sigma_variety |
(Optional) The variance of entry, default sigma_variety = (sigma_env * h2) / (1 - h2) |
mu_variety |
(Mandatory) The mean of the variety |
mu_check |
(Optional) The mean value of checks, default mu_check = 1.68 * sqrt(sigma_variety) |
cov_fun |
(Optional) The var-cov function ('exp' or 'gau'), default is 'exp', exponential |
ranges |
(Optional) The range parameter of spatial distribution, default sqrt(2) |
simulation |
(Optional) The number of simulated data returned, default 3 |
nugget |
(Optional) The nugget parameter in spatial simulation, default 0 |
mu_floor |
(Optional) The mean of the spatial floor, default 0 |
p_rep_check |
The density of checks in the p rep design, default 0.05 |
