asymPermute: Assess differences in amount and direction of asymmetric variation

Description

Assess differences in amount and direction of asymmetric variation

Usage

asymPermute(x, groups, rounds = 1000, which = NULL)

Arguments

x

object of class symproc result from calling procSym with pairedLM specified

groups

factors determining grouping.

rounds

number of permutations

which

select which factorlevels to use, if NULL, all pairwise differences will be assessed after shuffling pooled data.

Value

• dist
  difference between vector lengths of group means
• angle
  angle (in radians) between vectors of group specific asymmetric deviation
• means
  actual group averages
• p.dist
  p-value obtained by comparing the actual distance to randomly acquired distances
• p.angle
  p-value obtained by comparing the actual angle to randomly acquired angles
• permudist
  vector containing differences between random group means' vector lenghts
• permuangle
  vector containing angles between random group means' vectors
• groupmeans
  array with asymmetric displacement per group
• levels
  character vector containing the factors used
