The data set used here is risk (probability) and the probabilities are very small.  When using the summary function in R, the following is obtained

> summary(prob_ann)

##      Min.   1st Qu.    Median      Mean   3rd Qu.      Max. 
## 0.000e+00 1.000e-16 1.034e-13 3.959e-12 7.880e-13 8.222e-10

However, a query for the actual minimum yields the correct value:

> min(prob_ann)

## [1] 1.199446e-35

My question is this:  ¿why is summary using scientific notation, but still reporting a TRUE ZERO value instead of the correct value of 1.199e-35?
