Code without visible output:



In [1]:

    
a <- 8



In [2]:

    
b <- 4:59

With visible output:



In [3]:

    
a + b









    Out[3]:





 [1] 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36
[26] 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61
[51] 62 63 64 65 66 67

Printing is captured and sent to the frontend:



In [4]:

    
print('Hello world! Love, R in IPython.')









    



[1] "Hello world! Love, R in IPython."

So are errors:



In [5]:

    
h









    



Error in eval(expr, envir, enclos): Objekt 'h' nicht gefunden

Plotting works too:



In [6]:

    
x = seq(0, 2*pi, length.out=50)
plot(x, sin(x))
