cd data

We can make this function more robust by adding a simple error checking statement to prevent illegal parameters from generating invalid results.

qpareto <- function(p, scale, loc) {
    if ((scale <= 0) | (loc <= 0)) {
        stop("'qpareto' parameters must be greater than zero.")
    }
    q <- loc * (1 - p)^(-1/scale)
    return(q)
}

Entering a negative parameter now raises an exception, instead of an invalid result that could silently corrupt subsequent results.

qpareto(0.4, 5, -1)

## Error: 'qpareto' parameters must be greater than zero.

We could improve this further by checking to ensure that p is a valid probability.

## Warning: package 'ggthemes' was built under R version 2.15.3
