As an absolute beginner, still reading "Modern Applied Statistics with S" and exercising with its examples, I'm frequently stopped by what it looks to be R poor help system (or is it my gigantic ignorance?). I mean that using help many arguments of a command seems to be given for granted like for instance:
...............................
?lines
lines(x, ...)
## Default S3 method:
lines(x, y = NULL, type = "l", col = par("col"),
lty = par("lty"), ...)
Arguments:
x, y: coordinate vectors of points to join.
type: character indicating the type of plotting; actually any of
the 'type's as in 'plot'.
col: color to use. This can be vector of length greater than one,
but only the first value will be used.
lty: line type to use.
...: Further graphical parameters (see 'par') may also be supplied
as arguments, particularly, line type, 'lty' and line width,
'lwd'.

How could I quickly know during an R-session what values should be "col" set to have red, how could I set "lty" etc.?
