plot only a select few facets in facet_grid

ggplot2, r

Solution

Use `subset` in your `ggplot` call.

plot_1 = ggplot(subset(df, x %in% c(1, 2)), aes(x=z, y=y, fill=z)) +
         geom_bar(stat = "identity", position = "dodge") +
         facet_grid(. ~ x, scale = "free_y")

Problem

I was looking for a way to plot using `facet_grid` in `ggplot2` that only displays just a few select facets. say I have the following plot: Been looking for a quick way to, for instance, just plot facets 1 and 3. ``` #data y<-1:12 x<-c(1,2,3,1,2,3,1,2,3,1,2,3) z<-c("a","a","a","b","b","b","a","a","a","b","b","b") df<-as.data.frame(cbind(x,y,z)) #plot a <- ggplot(df, aes(x = z, y = y, fill = z)) b <- a + geom_bar(stat = "identity", position = "dodge") c <- b + facet_grid(. ~ x, scale = "free_y") c ``` Obviously I figured out how to just chop up my data first but this must of course be possible to allocate in `ggplot2` Even just a nudge would be most welcome.
