Quick command to assign a value to a variable and print it

Question

Basically I would like one command which replaces the following two commands:

temp <- 5^2-2
print("temp")

I would like to see the result of the calculation assigned to temp without having to use the print() command.

Answer 1

您可以将整个表达式放在方括号中。

(temp <- 5^2-2)

Answer 2

您可以通过以下方式进行组合：

temp <- print(5^2-2)

Answer 3

You may use the .Last.value function, like this:

temp <- 5^2-2
.Last.value

Hope it helps.
