Weird options(digits=n) behaviour

I noticed some very weird behaviour of the function: options(digits=n),
where n is the number of digits you would expect to get in R calculations.
Let's take a example:
options(digits=4) getdata(caso.pool.k3.r3.e2)
[1] 6.053 2.641 -3.639 14.259 6.082
Which works fine... now, trying again, with different data:
options(digits=4) getdata(controle.pool.k3.r3.e2)
[1] -0.03091 1.60310 -4.90588 5.07379 -0.04418
Which gives me 6 digits instead of 6. If I try digits=2, it then works with this data:
The 'digits' option sets the minimum number of significant digits. Some values in that array are printed to 6 significant digits but the first and last have only 4 significant digits.
