R help - May 2005 - How to convert array to c()

Dear R-helper,

Is there possible to make this array:
 > a <- array(1:12, c(4, 3))
 > a
      [,1] [,2] [,3]
[1,]    1    5    9
[2,]    2    6   10
[3,]    3    7   11
[4,]    4    8   12
 >

like:
c(1,5,9)
c(2,6,10)
c(3,7,11)
c(4,8,12)

Thank you very much in advance.
Regards,
Muhammad Subianto

Is this what you want?
> split(a, row(a))
$"1"
[1] 1 5 9

$"2"
[1]  2  6 10

$"3"
[1]  3  7 11

$"4"
[1]  4  8 12

Look at ?assign, one possible answer is shown in the examples.  Modified for
your example:

for (i in 1:nrow(a)) {
	nam <- paste("r",i, sep=".")
	assign(nam, a[i,])
}

would give you four separate objects r.1 to r.4 containing the 4 vectors.
Not sure if that's exactly what you wanted though.

How about?
p1<-a[1,]
p1
[1] 1 5 9
p2<-a[2,]
> p2
[1]  2  6 10
p3<-a[3,]
> p3
[1]  3  7 11
p4<-a[4,]
> p4
[1]  4  8 12
