This function transforms the k group labels to integers 1,...,k in a specified order.
Usage
createGroups(g, desOrder)
Value
A vector containing the new group numbers.
Arguments
g
Vector with group labels.
desOrder
Specified order for the groups.

Details
This function helps to renumber the group labels in a specified way.
The vector desOrder gives the old numbers as the function of the new numbers.
The first element of desOrder gives the old number that is transformed to be one, and so on.
The renumbering is used to specify alternative hypotheses.
The output is then a transformed vector g with new group numbers.
For non-numeric old group labels, the old number is the rank in the lexicographical order.
g <- c(rep(1,5),rep(2,6),rep(3,4))
createGroups(g,c(2,3,1))
# 'Smallest' letter should become 3, second smallest 2 and largest 1:g <- sample(c("A","B","C"),10,replace=TRUE)
createGroups(g,c(3,2,1))
