assign a list using expression?
Dear R-users,
I would like to assign elements to a list in the following manner:
mylist <- list(a = a, b = b, c = c)
To do this I tried
myexpr <- expression(a = a, b = b, c = c)
mylist <- list( eval(myexpr) )
It ends up by overwriting a when b is assigned and b when c is assigned.
Additionally the element of the list does not have a name.
Could you tell me why this is the case?
Thank you very much in advance!
Best regards,
Nils

a call like:
> asFunctionOf(expr, 'a',

Error: cannot allocate vector of size...

I was successful with the first .RDA file. Then I used the same commands with
another .RDA file (172 MB)which is 4 times bigger than the first file (41.2 MB).
When I put the last command
