Vectorise functions

[ms130]

The functions in this repository would be more useful if they were able to act on a vector, rather than only on a single value. For example, if you wanted to use the format_perc.R function to change fractions to percentages for an entire column, ready for insertion into a publication table.

I am stumbling into problems with this now as well. To vectorise them, do we just need to add sapply like this?

format_perc <- function(fraction, error_on_NA = TRUE) {formatted_percentages <- sapply(fraction, function(x) {...}) return(formatted_percentages)}
