stat2e {qgen} | R Documentation |
Calculates the narrow-sense heritability of plasticity and its confidence intervals.
stat2e(paraDATA, alpha=0.05, v=list( c(-1,1),c(0,1),c(1,0),c(1,1),c(1,-1) ), Satterthwaite=TRUE, file=FALSE, path="~/qgen/")
paraDATA |

v |
list with weights for the two environments; the indices |

Logical flag: Should the approximated degree of freedoms for sire and dam be used (only possible if they are available)? |
file |
Logical flag: Should the object be written to a file called " stat2e.rda "? |
path |
the path for the output files |
This function calculates the heritability of individual traits. If the
feeder provides parameters for several characters or several
environments or both, then for every character–trait combination
heritability is calculated individualy. If the feeder has a unbal
slot with data about the balancedness of the data set then also the
confidence intervals are calculated. If the feeder provides parameters
estimated with diffent variance partitioning methods then it is possible
to choose among them.
