[R] Converting factors to bounded random numerical data

I have a data set (a) with 3 columns (X,Y,Z). The first 2 columns are
numerical. The third column (Z) is a factor with three levels ("A","B","C").
What I want to do is turn each of the "A's" into different random numbers
between 1 and 4, "B's" into a random number between 5 and 8, etc.

I tried this:


That almost worked but changed all the A's to the same random number. I want
a different random number for each "A". Ideas?
