Prevent as.character from using exponential notation r

Question

Is there a way to prevent as.character from using exponential notation? For example, I have

num <- c(9999999, 10000000)
char <- as.character(num)
char
[1] "9999999" "1e+07"

But instead I would like to have char be "9999999" "10000000". Thanks!

Answer 1

format is the function that lets you choose how you want your numbers formatted when converting to character. In this case, something like

format(c(9999999, 10000000), scientific = FALSE, trim = TRUE)
#> [1] "9999999"  "10000000"
