Step 4.2

Is there any reason why this is only showing up to 2 sig-figs? I assume because last digit is 0? How do I make it appear 0 as well?

meanppl <- round(mean(dataC$Town Population (1000 pp), na.rm = TRUE),3)
meanppl

output
[1] 35.19

You are right - it's because of the final 0.

You don't need to fix this, but if you wanted to - there are (at least) three options. All of these turn the number into a character word (e.g. the quote marks). So you would no longer be able to use it for calculations, but its fine for printing out.

sprintf('%.2f', meanppl)
format(round(meanppl, digits=2), nsmall = 2)
formatC(meanppl,2,format="f")

Note to find this answer, I googled R round show final zero
which led me here - https://stackoverflow.com/questions/42105336/how-to-round-a-number-and-make-it-show-zeros

Note- in terms of code format - I would consider renaming your columns to something easy to type like population. It just makes it easier to write code in circumstances when you can't autoselect the column using $.
