What Is R?


1. Calculate the following numerical results to three decimal places with R:

(a) (7 − 8) + 53 − 5 ÷ 6 + 62

(b) ln 3 + 2 sin(π) − e3

(c) 2 × (5 + 3) − 6 + 92
(d) ln(5) − exp(2) + 23

(e) (9 ÷ 2) × 4 − 10 + ln(6) − exp(1)

Solution:

(a) 131.041
> round((7 - 8) + 5^3 - 5/6 + sqrt(62), 3)

[1] 131.041
(b) -18.987
> round(log(3) - sqrt(2) * sin(pi) - exp(3), 3)

[1] -18.987
(c) 94.551
> round(2 * (5 + 3) - sqrt(6) + 9^2, 3)

[1] 94.551
(d) 2.22
> round(log(5) - exp(2) + 2^3, 3)

[1] 2.22
(e) 13.911
> round(9/2 * 4 - sqrt(10) + log(6) - exp(1), 3)

[1] 13.911


2. Create a vector named countby5 that is a sequence of 5 to 100 in steps of 5.
