The correct way to set an element in a list to NULL? (FAQ is not clear)
http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-I-set-components-of-a-list-to-NULL_003f
The explanation on this FAQ entry is not clear. It says '... similarly
for named components...'. What I understood was x[i]<-list(NULL) is
the same as x$a_name<-list(NULL). But, they are not. As the example
below shows, x$a_name<-list(NULL) is the same as x[[i]]<-list(NULL).
> x=list(a=1:3,b=NULL,c=2:5,d=NULL)
> x
$a
[1] 1 2 3
$b
NULL
$c
[1] 2 3 4 5
$d
NULL
> x[[3]]=list(NULL)
> x
$a
[1] 1 2 3
$b
NULL
$c
$c[[1]]
NULL
$d
NULL...

Beginner in R
hello ( and sorry for my poor english ... )
I'm a newbie on R software and I need to obtain this kind of system :

my_struct$b <- another_value
my_struct$c <- one_more_value
and a function with two args : the first is a instance of the structure,
and the second is any component of the structure (here $a, $b

When the data gets saved, the first row in the Files table gets the
new product_id value that is also inserted into the Projects table,
but the child row does not, giving me results like:
Projects:
id: 1
name: A_Name
Files:
id: 1
project_id: 1
parent_id: null
filename: foo
id: 2
product_id: 0 <---------------------- Should this not be 1?
parent_id: 1
filename: bar
Firstly, am I doing things right? If so, is this a bug, or is this
how things were intended to work? Surely all rows in the...
