Facet label merging into a single row ggplot2

Question

I have created the following plot using ggplot in R:

the code:

ggplot(hola, aes(.fitted, .resid, color=type)) +
       geom_point() +
       geom_hline(yintercept = 0, color="black") +
       geom_smooth(se = FALSE, color="darkblue")+facet_wrap( type~exp, scales = "free") +
        scale_color_manual(values=c("#5fb772", "#5fabb7"))

However, I think the facet_wrap labels look too big and decompensate the overall graphics looking; is there a way to display it in a better looking way? like merging two columns of the df into one? or merging facet labels in a single row?

PD: By the way, using a facet_grid is not an options since X axis from mu and abs are different.

"to display it in a better looking way"... By "it" you mean graph itself or facet labels? — pogibas, Aug 15 '17 at 18:47
How about you merge data by letter (ie., abs F with mu F) and plot them on one graph. Because now colors don't add anything. — pogibas, Aug 15 '17 at 18:50

Does this help?

ggplot(hola, aes(.fitted, .resid, color=type)) +
       geom_point() +
       geom_hline(yintercept = 0, color="black") +
       geom_smooth(se = FALSE, color="darkblue")+
       facet_wrap( type~exp, scales = "free", labeller = label_wrap_gen(multi_line=FALSE)) +
       scale_color_manual(values=c("#5fb772", "#5fabb7"))

ggplot(hola, aes(.fitted, .resid, color=type)) +
   geom_point() +
   geom_hline(yintercept = 0, color="black") +
   geom_smooth(se = FALSE, color="darkblue")+
   facet_wrap(paste(type, exp, sep = ":"), scales = "free") +
   scale_color_manual(values=c("#5fb772", "#5fabb7"))

This simply makes a new anonymous variable for each level of type and exp with values of "abs: exp_F", for example. Then there is only one row of labels for each panel.
