str	A character string giving groups
rlevels	A character string giving levels
make.names	Logical, should names be converted to adhere to the rule of variable names in R

rgroup <- "A,B,C,D,B,C,A,D,B"
rlevels <- "D,A,B,C"
parseFactor(rgroup, rlevels)

groups <- c("ATest", "Control", "Control", "ATest")
levels <- c("Control", "ATest")
makeFactor(groups, levels)

# if 'groups' is a factor and 'levels' NULL or missing, its levels are respected
groups <- factor(c("B", "C", "A", "D"), levels=c("D","C","A","B"))
makeFactor(groups)

## Not run: 
groups <- c("ATest", "Control", "Control", "ATest")
levels <- c("Control", "ATest", "Unknown")
