how do i round numbers in a column in R?

Question

How do I round the numbers to 2 decimal points within a column within a dataframe?

The name of the df is tax_data and the column that I want to round is called rate_percent

I tried using:

format(round(rate_percent ,2), nsmall =2) but this didn't work.

Does anyone have any suggestions?

Here is a `tidyverse` option to replace the values in the rate_percent column with the rounded version. `tax_data %>% mutate(rate_percent = round(rate_percent, 2))` — , Apr 28 '20 at 15:32

Here, in Base-R

tax_data$rate_percent <- round(tax_data$rate_percent ,2)
