Dear
I use dataset , as called "mpg"
This is code
ggplot(data=mpg)+ geom_point(mapping = aes(x=displ, y=hwy, colour=year))
But I would like to see only "year of 1999" in this relationship between x
and y variables
How could I change the code in this direction?
I found the following code
library(dplyr)year_1999 <- filter(mpg, year=="1999")ggplot(year_1999,
aes(x=displ, y=hwy)) + geom_point()
I found other code
ggplot(data = mpg, mapping = aes(x = displ, y = hwy)) +
geom_point(
data = filter(mpg, year == "1999")
)
Is there more compact code ?
sincerely
Engin YILMAZ
