Well, it's a little inelegant, but since the amount of information is the same in events that are certain to occur and certain not to occur, you could add the line prob[prob==0] <- 1 after you set up the prob vector, which would take care of the problem.

prob <- c(0.5,0.4,0.3,0.1,0.0) cal <- prob * log(prob,base=2) cal
[1] -0.5000000 -0.5287712 -0.5210897 -0.3321928 NaN Is there any way to change NaN to zero ?
