Dear R-devel,
When a character vector is used to subscript a list and when some of the
subscripts are not present in the list names R returns NULL for those
subscripts and generate NA names for each of them:
> list(b=1)[c('a','b')]
$<NA> <<-- generated name
NULL
$b
[1] 1
Wouldn't it be more intuitive to use the subscript name rather than to generate
an NA? Something like this (not real result):
> list(b=1)[c('a','b')]
$a <<-- more intuitive name
NULL
$b
[1] 1
