You can argue that the coercion to a list is redundant, since a data frame is a
list, but it may depend upon what you then want to do with the data.

, where I default to the use of ctable, as I prefer the look. One
approach instead of removing the blank lines, is to just comment them out (eg.
using a '%' character).
I am cc'ing Frank here, in case he is not aware of this, albeit I presume that
he is and that this behavior is a buglet.

Since a matrix can only contain a single class of objects (recall that a matrix
is a vector with dim attributes), 'iris' becomes a character matrix.

a version bump during that time frame. R-Forge packages will not have
the same frequency of commits, but the same approach can be applied.
So you need to differentiate between the ongoing development/commit process and
the versioned release process.

Hi,
If you should decide to pursue the LaTeX approach, you would want to install
MacTeX on your Mac. More information here:
http://www.tug.org/mactex/2009/
MacTeX is a self contained distribution of TeX Live 2009. It also provides an
easy to use GUI based maintenance tool to add packages
