r - Specifying different axis labels between facets -

i specify breaks , colors 2 facets independently. there way this?

using code

ggplot(data, aes(x = x, y = y)) +     geom_point() +     scale_y_continuous(breaks = c(0:3, 4, 6, 8)) +     facet_wrap(~group, scales = "free") 

i can add additional breaks need on bottom facet, don't want these top. in other words, i'd have 0, 1, 2, 3 bottom plot , 0, 2, 4, 6, 8 top plot.

i don't have idea of how specify different colors labels between facets (let me know if should open separate question colors).

one way plot each group separately, lay out plots together:

library(gridextra)  p1 = ggplot(data[data$group=="group1",], aes(x = x, y = y)) +        geom_point() +        scale_y_continuous(breaks = c(0:3, 4, 6, 8)) +        facet_wrap(~ group)  p2 = ggplot(data[data$group=="group2",], aes(x = x, y = y)) +        geom_point() +        scale_y_continuous(breaks = c(-1:3)) +        facet_wrap(~ group)  grid.arrange(p1, p2, ncol=1) 

if can come rule programmatically deciding y-breaks, can plots @ once using lapply. here's simple example. use case, you'll need see if can come rule or rules work plots.

# store plots in list pl = list()  pl = lapply(unique(data$group), function(i) {   ggplot(data[data$group==i,], aes(x,y)) +     geom_point() +     facet_wrap(~ group) +     scale_y_continuous(limits=c(min(data$y[data$group==i]), max(data$y[data$group==i])), breaks=min(data$y):max(data$y)) })  do.call(grid.arrange, c(pl, ncol=1))
