Calculates the differences of mean observed outcomes for multiple specified treatment factors and specified pairs of comparison levels.
1  diffMeansVector(y, w, calcOptions)

y 
a vector or matrix of outcomes. 
w 
a vector or matrix of assignments. 
calcOptions 
a list of options for calculating the vector of differences of mean outcomes.

If unspecified, calcOptions$pairs
defaults to c(0,1)
.
If calcOptions$factors
is specified, its length must equal the number of rows specified in calcOptions$pairs
.
If unspecified, calcOptions$factors
defaults to an appropriatelysized vector of 1
's.
A vector of differences of mean observed outcomes.

1 2 3 4 5 6 7 8  ## 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)
