I am plotting median values across using geom_raster in ggplot and am placing data labels using the main aesthetic line and rounding to the hundredth decimal, similar to:
ggplot(data, aes(x=var1,y=var2, label=round(median,2)))
Unfortunately if the hundredth ends in a 0, it truncates to the tenth decimal. In the below image, you can see this issue a couple of places, such as in the top right corner with two values of 0.3.
I tried label=signif(round(k_median,2),2) which did not solve the issue and inappropriately truncates values >1 to the hundredth. I also tried putting the label in the geom_text line (i.e. ggplot(...) + geom_text(aes(label=round(k_median,2)),...) but that also resulted in the same issue.
What I am doing wrong? Is there an alternative way to solve this issue?
Below is my full code that created the figure:
ggplot(subset(sims.summary,type==2 & k_median<3),aes(x=p1,y=p2, label=round(k_median,2)))+
geom_raster(aes(fill = k_median),hjust=0, vjust=0)+
scale_fill_distiller(palette = "Spectral", direction = -1)+
xlab("Passive Probability")+ylab("Active Probability")+
scale_x_continuous(limits=c(0,1),breaks=seq(0,1, by=0.1))+
scale_y_continuous(limits=c(0,1),breaks=seq(0,1, by=0.1))+
annotate("rect", xmin = 0.1,xmax=0.2,ymin = 0.5, ymax=1, fill="#9E0142")+
annotate("rect", xmin = 0.2,xmax=0.3,ymin = 0.9, ymax=1, fill="#9E0142")+
annotate("rect", xmin = 0,xmax=0.1,ymin = 0.2, ymax=1, fill="#9E0142")+
geom_text(size=3, hjust=2, vjust=3.5)+
theme(axis.text.x = element_text(hjust=3))+
theme(axis.text.y = element_text(vjust=2.5))
