To the best of my knowledge, apart from its specific use as a separator
between the integer and fractional parts of a number, "." has no specific
use in R, and you can, for instance, use it just as you would use an
alphanumeric character in a name.

For instance, you could do

  . <- 1.2345
  # [1] 1.2345

  . <- function(x) x^2
  # [1] 144

So, unless there is something I don't know about, there is hardly
anything to discuss about "the detailed usage of '.' in R"!
