if by array, you just mean vector, then the following would work .

stack(myList)

If you want to take off the names of myList that get put in the second
column

stack(myList)[,-2,drop=FALSE]

Subject: [R] converting list to an array

Hi,
 
I have a list myList (see below) that consists of id's $'7',....,$'10'
and each id has an individual array, the length of which can vary from
id to id.
 
How can I convert this list into an array, ie. stacking the individual
arrays into one large array?
 
 
Thanks
 
Zava
 
 
myList:
 
$`7`
[1] 20050201 20050301 20050401 20050501
 
$`8`
[1] 20050201 20050301 20050401 20050501
 
$`9`
[1] 20050201 20050301 20050401 20050501
 
$`10`
[1] 20050101 20050201 20050301 20050401 20050501
