Hi Chris,
Hi Elea,

could you correct this please:

Wrong:

p1.table2[, 2] / p1.table2[, 1] + p1.table2[, 2]
    2.19     2.29     2.49     2.79     2.99 
41.11582 46.11558 42.11024 47.11869 32.09329 

Correct:

p1.table2[, 2] / ( p1.table2[, 1] + p1.table2[, 2] )
      2.19       2.29       2.49       2.79       2.99 
0.10379747 0.10360360 0.09929078 0.10609481 0.08533333 

Best regards
