I apologize in advance if this is posted all ready I have not been able to
find any information about it.  I have this data frame and I want to sort
smoking by retlevel.

     Age Gender   BMI      Calories  Fat Fiber   Alc     retlevel
Smoking
1    64  Female 18.87834   1828.0  63.4  14.7  0.0     Normal     Non-Smoker
2    25  Female 20.64102   1517.4  59.1   5.9   0.0     Normal      Smoker
3    50  Female 20.40345   1902.9  72.9  35.4  7.3     Normal    Non-Smoker
4    32  Female 35.97525   3328.4 163.3  20.0  4.1      High         Smoker
5    43  Female 25.58279   2501.6 121.1  19.5  0.0      High         Smoker
6    39   Male   21.99912   1951.4   109.1   4.7   0.0     Normal     Smoker

To get an output like this.

retlevel            Normal  High
Smoking             2         2
Non-smoker        1         1
