Hello Team,
I can run the function below:
library(tidyverse)
f2 <- function(indata, subgrp1){
indata0 <- indata
temp <- indata0 %>% select({{subgrp1}}) %>% arrange({{subgrp1}}) %>%
group_by({{subgrp1}}) %>%
mutate(numbering =row_number(), max=max(numbering))
view(temp)
f_table <- table(temp$Species)
view(f_table)
return(f_table)
}
f2(iris, Species)
You can see the second argument I use Species only, and it works fine.
But If I say, I want the 2nd argument = Petal.Width, Species , how should I
write the argument? I did try f2(iris, c(Petal.Width, Species)), but I got
error message:
Error: arrange() failed at implicit mutate() step.
* Problem with `mutate()` column `..1`.
i `..1 = c(Petal.Width, Species)`.
i `..1` must be size 150 or 1, not 300.
I'm not sure how to fix the problem either in function or can fix it when using
the function.
Thank you,
Kai
