# print() and cat() fuctions 


 print('hello R!')   

# [1] "hello R!"

# Note that “\n” is not working for the print() function. 
 print('hello world\n')   

# [1] "hello world\n"

# We could also print a defined variable.
 x<-'this is great'
 print(x)
 
# [1] "this is great"


cat(x,"\n")    # \n means changing line
