x <- as.logical(rvbern(1,0.4)) # a logical random variable is.fuzzy(x) # TRUE, since x is logical and not constant is.fuzzy(x<2) # FALSE, since x is less than 2 with probability one is.fuzzy(rvnorm(1)) # FALSE, since it's not a probability is.fuzzy(TRUE) # FALSE, since TRUE is strictly TRUE is.fuzzy(1) # FALSE, since 1 is not a logical variable
