Adjust specific text lables in ggplot to avoid overlap
ggplot2, label, plot, r
Solution
If the data value being overlapped is not very important, a quick and dirty solution is to specify:
+ geom_text(size = 5, check_overlap = T)
So that text overlap previous text will not be plotted.
Problem
Given a dummy data set: ``` V1<-c(1,10,30,22,22,20) V2<-c(4,17,4,33,33.2,15) V3<-c(20,20,15,34,33,30) V4<-c("A","A","A","B","B","B") DF<-data.frame(V1,V2,V3,V4) ``` If I were to plot a bubble plot like so: ``` symbols(DF$V1,DF$V2,circles=V3,inches=0.35,fg="darkblue",bg="red") text(DF$V1,DF$V2,V4,cex=0.5) ``` I get some overlap with the 4th and 5th label text. Using the below code, I can remove this overlap by adjusting specific points ``` text(DF$V1,DF$V2+c( 0, 0, 0, 1, -1,0 ),V4,cex=0.5) ``` Which works fine, but I would like to work in ggplot. If I do a simple ggplot ``` ggplot(DF,aes(x=V1,y=V2,size=V3,label=V4),legend=FALSE)+geom_point(color='darkblue',fill="red", shape=21)+theme_bw()+geom_text(size=5) ``` I get the same overlap, but I don't know how to adjust the individual points to avoid the overlap. I've tried using "thigmophobe.labels", but that adjusts all points. I'd like to just slightly adjust the points that overlap as to make them readable.
