search for: year_1999

...ed "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 Y...
