Think about what value each of the following expressions will return?
Check your answers using the R Console by typing each expression into
the console on the line marked >
and pressing enter.
Did any of the results surprise you? If so, then might have run in to some order of operations confusion. The order of operators in R are listed HERE.
Now turn this set of expressions into a program that you can save by using an R script. For each expression add one line to the script as part of a print statement. Copy and paste the script into the console to display the answer to the screen. If you are using RStudio, you can use Ctrl+Enter (Windows & Linux) or Command+Enter (Mac) to run the line or selection of code directly from your script.
To tell someone reading the code what this section of the code is about,
add a comment line that says ‘Problem 1’ before the code that answers
the problem. Comments in R are added by adding the #
sign.
Anything after a #
sign on the same line is ignored when the program is
run. So, the start of your program should look something like:
# Problem 1
print(2-10)
