Path, TestDirection = "Descending",alpha=0.05)

Arguments

Data

A data set.

TreatVar

Name (as a string) of the treatment variable.

ResponVar

Name (as a string) of the response variable.

RepVar

Name (as a string) of the replicate variable.

TimeVar

Name (as a string) of the time variable.

Path

Path indicates the type of mixed effects analysis performed. Use Path = 2 for Time (Repeated Measures) and Path = 3 Group - Replicate (Mixed Effects).

TestDirection

Indicates the test direction. This can be c('Both', 'Descending', 'Ascending').

alpha

Alpha level used in calculating confidence intervals.

Details

This is mostly a wrapper function for nlme from the nlme package and glht from the multcomp package.

Value

Returns a list with the following items:

Anova.Table

An ANOVA table see Anova.

MainEffects

A table of main effect, see oneWayDunnettTest for more details.

FreqTable

A table of frequencies of occurrences for every sub group in the data set.
