Dear R-friends,

I have whole bunch of objects, say, A, B, ..., Z,
all of them are "list" and haveing "Title" (a character string)
as their first element.
  > A$Title
  [1] "Airplane Component"

What I like to do is to find a way to printout all the Titles at one
I tried the following:
  >  paste(LETTERS, "Title", sep="$") -> tmp
but can't find a way to continue since
  > get(tmp[1])
  Error in get(x, envir, mode, inherits) : variable "A$Title" was not

Is there a way to create a vector of A$Title, B$Title, ... without
double quotes?

My version is
> version
platform Windows
arch     x86
os       Win32
system   x86, Win32
