I try to calculate descriptive statistics for one of the variables in the
data frame, however command sapply calculates these statistics for every
value of the variable separately. How to make it calculate range (as well as
other statistics) for all column?

Here are commands and results:

> as1$trust
 [1]  5.957510  5.888664  6.168135  6.419472  5.668796  6.026923
6.456721  7.017946  5.294411

[10]  7.296844  6.479167  5.009000  7.149073  5.932667  5.991000

10.695650  5.490983  7.290476
