'sprintf' if your friend:
> dummy3 = c(1.1, 2.2, 3.3)
> dummy4 = c(4.4, 5.5, 6.6, 7.7)
> dummy2 = c(8.8, 9.9)
>
> cat(sprintf("%5.1f%6.2f%7.3f\n", dummy3[1], dummy3[2], dummy3[3]))
1.1 2.20 3.300
> cat(sprintf("%5.2f%6.3f%7.4f%8.5f\n", dummy4[1], dummy4[2], dummy4[3], dummy4[4]))
4.40 5.500 6.6000 7.70000
> cat(sprintf("%5.3f%6.4f\n", dummy2[1], dummy2[2]))
8.8009.9000
