Hi everyone,
One suggestion would be import ggplot2 and using tidy eval operators to
create a function. One simple reproducible example would be
library(ggplot2)
my_hist <- function(df, var){
ggplot(df, aes({{var}})) +
geom_histogram()
}
df <- data.frame(my_var = rnorm(400, 10, 2))
my_hist(df = df, var = my_var)
All the best
Tiago
