Calculates the differences of mean observed outcomes for multiple specified treatment factors and specified pairs of comparison levels.
diffMeansVector(y, w, calcOptions)
a vector or matrix of outcomes.
a vector or matrix of assignments.
a list of options for calculating the vector of differences of mean outcomes.
calcOptions$pairs defaults to
calcOptions$factors is specified, its length must equal the number of rows specified in

## 2 treatment factors, each with 3 levels ## Assignments, outcomes, and desired pairs w1 = c(1,2,3,1,2,3,1,2,3) w2 = c(1,2,3,2,3,1,3,1,2) w = cbind(w1,w2) y = c(4,6,5,7,4,7,11,9,10) diffMeansVector(y, w, calcOptions = list(factors = c(1,1,2), pairs = rbind(c(1,2),c(2,3),c(1,3)))) ## Equals c(-1,1,0)
