Proceed to a variance analysis of the vector of data
x associated with the vector of factors clusters. It returns
a data.frame containing the name of the groups
motif, the group size number, the group mean
mean and standard deviation sd, and the two-to-two
differences expressed in the form of letters group.
test_posthoc(x, clusters, pvalue = fpvalue())a numeric vector.
a vector of factors of length(x).
a marginal p-value.
Return a data.frame containing
the name of the groups motif,
the group size number,
the group mean mean and standard deviation sd,
and the two-to-two differences expressed
in the form of letters group.
The function test_posthoc() uses Tukey method.
Different groups are sorted by decreasing means.
Letter rank increases with decreasing means.
