MPP GxE QTL genetic effects

Description

Compute MPP GxE QTL genetic effects

Usage

mppGE_QTL_effects(
  mppData,
  trait,
  Q.eff = "cr",
  VCOV = "CS_CSRT",
  QTL = NULL,
  workspace = 8e+06
)

Arguments

mppData

An object of class mppData.

trait

Character vector specifying which traits (environments) should be used.

Q.eff

Character expression indicating the assumption concerning the QTL effects: 1) "cr" for cross-specific; 2) "par" for parental; 3) "anc" for ancestral; 4) "biall" for a bi-allelic. Default = "cr".

VCOV

VCOV Character expression defining the type of variance covariance structure used. "ID" for identity, "CSRT" for within environment cross-specific residual terms, "CS_CSRT" for compound symmetry with within environment cross-specific residual terms. Default = "CS_CSRT".

QTL

Object of class QTLlist representing a list of selected marker positions obtained with the function QTL_select() or a vector of character marker positions names. Default = NULL.

workspace

Size of workspace for the REML routines measured in double precision words (groups of 8 bytes). The default is workspace = 8e6.

Value

Return:

Qeff

List of data.frame (one per QTL) containing the following information:

  1. QTL genetic effects

  2. Standard error of the QTL effects.

  3. Test statistics of the effects (t-test or Wald statistic).

  4. P-value of the test statistics.

  5. Significance of the QTL effects.
