[R] How to print the objects in the memory

[usstata]

Hi,all:

	May be a  pointless question
	
	a <- 1:10
	b <- matrix(1:8,nrow = 4)
	c <- letters[4:8]  
	¡­¡­
	
	> ls()
	[1] "a"      "b"      "c"  

	ls() can print the names of the objects in the memory ,
	
	but I want to get the result :
> a
[1]  1  2  3  4  5  6  7  8  9 10
> b
     [,1] [,2]
[1,]    1    5
[2,]    2    6
[3,]    3    7
[4,]    4    8
> c
[1] "d" "e" "f" "g" "h"
¡­¡­

 		I try the command print(noquote(ls()))	which it can't help
		
	
Best regards
