i'm producing facet wrapped forest plot , i'd manually set y-axis labels.
here's example data:
set.seed(1) df <- data.frame(x=rnorm(10),y=c(1:5,1:3,1:2), group=c(rep("a",5),rep("b",3),rep("c",2)), name=c(paste("a",1:5,sep=""),paste("b",1:3,sep=""),paste("c",1:2,sep=""))) df$xmin <- df$x-runif(10,0.5,0.7) df$xmax <- df$x+runif(10,0.5,0.7) and here's code i'm trying:
library(ggplot2) p <- ggplot(df,aes(y = y, x = x))+ geom_point()+ scale_y_discrete(limits = df$name, expand = c(.1,0))+ facet_wrap(~group,ncol=3,scales="free")+ geom_segment(aes(x = xmin, xend = xmax, y = y, yend = y))+ geom_vline(lty=2, aes(xintercept=0), colour = 'red') which produces figure:
as can see y-axis tick labels of middle , right facets not consistent df$name.
ggplot(df,aes(y = name, x = x)) + geom_point() + facet_wrap(~group,ncol=3,scales="free") + geom_segment(aes(x = xmin, xend = xmax, y = name, yend = name)) + geom_vline(lty=2, aes(xintercept=0), colour = 'red')
