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.
E.g.,
> A$Title
[1] "Airplane Component"
What I like to do is to find a way to printout all the Titles at one
time.
I tried the following:
> paste(LETTERS, "Title", sep="$") -> tmp
but can't find a way to continue since
> get(tmp[1])
Error in get(x, envir, mode, inherits) : variable "A$Title" was not
found
Is there a way to create a vector of A$Title, B$Title, ... without
double quotes?
My version is
