Co-Occurr Package (ggplot2 adjustments)

Ive' been using the R package "cooccur" to measure co-occurrence among bird species, a package that produces its own R objects. I am not very familiar on this and want to make changes to the sizes of its x and y labels.

I'm trying to adjust the size of the font of the plot but using theme(), I've been successful in changing the angle of the second plot but have not had any success with adjusting font size for both. This only changes the position of the graph for some reason.

Note: These graphs are created as ggplot2 objects from the specific package I am using for this analysis.

(I'm not sure if this belongs to this community specifically though, I'm just curious also if others have used this package).

help please :/

library(devtools)
#install_github("griffithdan/cooccur") library(cooccur)

options(stringsAsFactors = FALSE)

data(finches) cooccur.finches <- cooccur(mat=finches,
               type="spp_site",
               thresh=TRUE,
               spp_names=TRUE) summary(cooccur.finches)

#CoOccurrence Plot species_cooccurrence_plot <- plot(cooccur.finches)+ ggtitle("Species Co-Occurrence Matrix") +   theme(text = element_text(size=5))
#View Co-Occurrence Plot species_cooccurrence_plot

#Creation of Species Association Profile species_association_profile <- pair.profile(cooccur.finches) + ggtitle("Species Associtation Profile") +
    theme(text = element_text(size=5),
          axis.text.x = element_text(angle=90, hjust=1))

#View Association Profile

If you want to change axis text size then it has to be part of the element_text that controls the axis:

element_text(angle=90, hjust=1, size=5)
