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

Hi, what about this one? ggplot(data=mpg[mpg$year==1999,], aes(x=displ, y=hwy))+ geom_point() Best, Robin On 10/21/20 3:37 PM, Engin Y?lmaz wrote:> 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 > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- Dr. Robin Haunschild Max Planck Institute for Solid State Research Heisenbergstr. 1 D-70569 Stuttgart (Germany) phone: +49 (0) 711-689-1285 fax: +49 (0) 711-689-1292 email: R.Haunschild at fkf.mpg.de http://www.fkf.mpg.de/ivs Publons: https://publons.com/researcher/2845202/robin-haunschild/ GS: https://scholar.google.de/citations?user=kDfateQAAAAJ&hl=de&oi=ao
Hello, You can subset the data argument. And if you are plotting one year only, there's no point in color = year. ggplot(subset(mpg, year == 1999), aes(displ, hwy)) + geom_point() If you are loading package dplyr, you can filter directly to ggplot: library(dplyr) mpg %>% filter(year == 1999) %>% ggplot(aes(displ, hwy)) + geom_point() Hope this helps, Rui Barradas ?s 14:37 de 21/10/20, Engin Y?lmaz escreveu:> 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 > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
