Find the smallest value in each column of the frame.



The frame will have one row and the same number, names and stypes of columns as in the current frame. For string/object columns this function returns NA values.

  • .min1() – similar to this method, but operates on a single-column frame only, and returns a scalar value instead of a Frame.

  • dt.min() – function for counting min values in a column or an expression; can also be applied per-group.
