I would like to change the position of the word 'Richness' in this bar graph. I would like the word to align with the position of the first word of the other labels, i.e. be placed in the top line rather than the bottom line.
p0 <-
ggplot(lineshift, aes(x=name, y=value, fill=factor(product))) +
geom_bar(stat="identity", position="dodge", width=0.8) +
geom_text(aes(x=name, y=value, ymax=value, label=round(value),
hjust=0.5, vjust=-0.5),
position = position_dodge(width=0.8)) +
scale_fill_manual(values=c("blue", "red"),
name="Treatment",
breaks=c(1, 2),
labels=c("A", "B")) +
xlab("Biodiversity") +
ylab("Relative occurences (%)") +
scale_y_continuous(expand=c(0.0,0.5),
limits=c(0, 71),
breaks=c(0,10,20,30,40,50,60,70),
labels=c("0","10","20","30","40","50","60","70")) +
scale_x_discrete(limits=c("Biodiversity of tropical lowland rainforest", "Species composition in understorey", "Richness"),
labels = sapply(strwrap(as.character(lineshift$name), width=30, simplify=F), paste, collapse="\n")) +
theme_bw() +
theme(legend.position=c(0.9,0.9)) +
theme(legend.title=element_blank()) +
theme(axis.title.x = element_text(vjust=0.1,face="bold", size=16),
axis.text.x = element_text(vjust=0.1, size=14, angle=0))+
theme(axis.title.y = element_text(angle=90, vjust=0.70, face="bold", size=18),
axis.text.y = element_text(size=14)) +
theme(panel.grid.minor=element_blank(), panel.grid.major=element_blank()) +
theme(panel.border = element_rect(size=2, colour = "black", fill=NA, linetype=1)) +
theme(plot.margin = unit(c(0.3,0.4,0.28,0.0),"lines"))
This is the data:
structure(list(product = c(1L, 1L, 1L, 2L, 2L, 2L), name = structure(c(1L,
3L, 2L, 1L, 3L, 2L), .Label = c("Biodiversity of tropical lowland rainforest",
"Richness", "Species composition in understorey"), class = "factor"),
value = c(62.96, 22.22, 14.81, 60, 40, 0), treatment = structure(c(1L,
1L, 1L, 2L, 2L, 2L), .Label = c("A", "B"), class = "factor")), .Names = c("product",
"name", "value", "treatment"), class = "data.frame", row.names = c(NA,
-6L))
Many thanks for any advice.

You can change vjust in the theme for the x-axis text:
