Run coin-flipping like permutation tests (to compare difference of 2 means: 'x1' and 'x2') without any distribution-assumptions. This function uses the package coin, if not installed, the function will return NULL and give a warning.

Usage

coinPermTest(
  x1,
  x2,
  orient = "two.sided",
  nPerm = 5000,
  silent = FALSE,
  debug = FALSE,
  callFrom = NULL
)

Arguments

x1

numeric vector (to be compared with vector 'x2')

x2

orient

(character) may be "two.sided","greater" or "less"

nPerm

(integer) number of permutations

silent

(logical) suppress messages

debug

callFrom

(character) allow easier tracking of messages produced

Value
