FieldSimR is an R package for simulating realistic plot data in multi-environment field trials with one or more traits. Its core function generates plot errors comprising:

  • spatially correlated error (trend),
  • random error (noise), and
  • extraneous error.

Spatially correlated errors are simulated using either bivariate interpolation or a separable first order autoregressive process (AR1:AR1). The three error terms are combined at a user-defined ratio.

Plot phenotypes can be generated by combining the simulated errors with genetic values (e.g. true, simulated or predicted). FieldSimR provides wrapper functions to simulate genetic values for multiple traits across multiple environments using the R package AlphaSimR.


FieldSimR is available on CRAN.
