For print(), digits is the minimal number of significant digits. In
your case, rounding the first column to the 3rd decimal place gives at
least 2 sigfigs and rounding the second column to the 2nd decimal
place.
If you want to print all numbers to two significant digits, regardless
of what other numbers are in the column, use signif() before print():

R will still print 3 decimal places for the third column since it
wants them to be of the same format, but each number is 2 sigfigs.

Hi, I have two variables with 86 observations each. Below I print with
