This is strange the first function that I am doing this for is saying in the
typeof() is a double for some reason this is coming up as a list.  

> str(spread)
'data.frame':   18 obs. of  1 variable:
 $ bootdataframe.age: num  1.46e-09 1.67e-09 1.46e-09 1.45e-09 1.37e-09 ...
> typeof(spread)
[1] "list"
> class(spread)
[1] "data.frame"
