Hi there,

    pregnant glucose diastolic triceps insulin  bmi diabetes age test
1          6     148        72      35       0 33.6    0.627  50    1
2          1      85        66      29       0 26.6    0.351  31    0

    pregnant glucose diastolic triceps insulin  bmi diabetes age test
1          6     148        72      35       0 33.6    0.627  50    1
2          1      85        66      29       0 26.6    0.351  31    0

As you can see, I can already use pima without running data(pima),
after running data(pima), it looks the same. So what's the reason to
use data(pima) ?

Thanks

YJM
