Examples


## generate estimated proportion matrix
estProp <- matrix(abs(runif(50*4,0,1)), 50, 4)
estProp <- sweep(estProp, 1, rowSums(estProp), "/")

## generate reference proportion matrix
refProp <- matrix(abs(runif(50*4,0,1)), 50, 4)
refProp <- sweep(refProp, 1, rowSums(refProp), "/")

estProp_aligned = assignCellType(input = estProp,
reference = refProp)
