Code without visible output:



In [1]:

    
a <- 8



In [2]:

    
b <- 4:59

With visible output:



In [3]:

    
a + b

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))
