[R] editing import data, strings

[R. Michael Weylandt <michael.weylandt@gmail.com>]

It looks like you've gotten answers elsewhere, but for completeness, I'll explain my shot in the dark:

The construction 

function (x) sin(x^2) 

to pick one example, is what's called an anonymous (or lambda) function. In R, they are often used in conjunction with the *apply() family to describe a set of operations to be done column/rowwise on your data. For example, there are the same:

apply(d, 2, sin)
apply(d, 2, function(x) sin(x))
apply(d, 2, function(y) sin(y))
apply(d, 2, function(d) sin(d))

As you can see, the "x" is simply a place holder variable, not really tied to anything. 

Hope this helps,
Michael
