Facet label merging into a single row ggplot2

I have created the following plot using ggplot in R:

enter image description here

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.

Solution

  • 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"))
