I've made a graph of mean cover of different species in 3 different areas with the inclusion of one species (y) and exclusion of the same species (n) on different graphhs. however I'm struggling to place the two graphs of y and n together in Rstudio for comparison
please can you help?
composistino3 %>%
group_by(site, bartsia, species) %>%
summarise(meancover = mean(cover),
secover = sd(cover)/sqrt(n())) %>%
ungroup() %>%
ggplot(aes(x = reorder (species, - meancover), y = meancover, colour = species, fill = species, group = species)) +
geom_bar(stat="identity", position = "stack") +
labs(x = "Species",
y = "Mean Cover") +
theme(axis.text.x = element_blank(),
axis.ticks.x = element_blank()) +
#geom_errorbar(aes(ymin = meancover - secover, ymax = meancover + secover)) +
facet_wrap(~bartsia+site, ncol=2)
