Expected gain from multistages selection This package calculate the gain from selection, which is described by Cochran (1951). For one-stage selection the gain is defined as \eqn{\Delta G (y) = i \rho_{y} \rho_{1}}, where \eqn{i} is the selection intensity, \eqn{\rho_{1}} is the correlation between the true breeding value and the selection index \eqn{y} (Utz1969). The numerical calculation is based on Tallis' algorithm (Tallis1961). Software Depends: R (>= 2.13.0), mvtnorm Xuefei Mi <mi@pz.uni-hohenheim.de> Xuefei Mi, Friedrich Utz, Albrecht E.
