Use human-readable matrices in documentation examples

[patrickbarks]

I propose using a consistent, human-readable format when creating matrices in the @example section of Rage functions, e.g.

Format 1

matU <- rbind(c(  0,   0,    0,   0),
              c(0.1, 0.1,  0.1,   0),
              c(  0, 0.3,  0.3, 0.1),
              c(  0,   0,  0.2, 0.1))

Format 2

matU <- rbind(c(0.0, 0.0,  0.0, 0.0),
              c(0.1, 0.1,  0.1, 0.0),
              c(0.0, 0.3,  0.3, 0.1),
              c(0.0, 0.0,  0.2, 0.1))

I think Format 1 is slightly easier to read in the R documentation browser. Thoughts?

Good point. I find Formats super clear, but I marginally prefer Format 2.
