You can use aes_string
:
f <- function( column ) {
...
ggplot( rates.by.groups, aes_string(x="name", y="rate", colour= column,
group=column ) )
}
as long as you pass the column to the function as a string (f("majr")
rather than f(majr)
). Also note that we changed the other columns, "name"
and "rate"
, to be strings.
If for whatever reason you’d rather not use aes_string
, you could change it to (the somewhat more cumbersome):
ggplot( rates.by.groups, aes(x=name, y=rate, colour= get(column),
group=get(column) ) )
