Capacitance of different shaped capacitors.

SUMMARY:
       The capac data set has 15 rows and 5 columns. Each
       data  point  is  the capacitance of a capacitor built with
       one of 5  shapes  and  3  different  sizes  (area).  Other
       covariates  variables  are  perimeter length and number of
       discontinuities.

DATA DESCRIPTION:
       This data set contains the following columns:
capac:     No weighting of airplane nose.
shape:     Either  cir  (circle),  poly  (polygon),   star,
           tri (triangle), or squ (square).
perim:     perimeter
area:      9, 16, or 25 square inches
discont:   discontinuities, measures the unevenness of the perimeter.
