Error in `check_required_aesthetics()`: ! geom_dotplot requires the following missing aesthetics: y-CodePudding

The problem is that whilst I try to plot using geom_dotplot, I receive the error:

 Error in `check_required_aesthetics()`:
! geom_dotplot requires the following missing aesthetics: y

The data for this problem is:

sum.qmerge<-structure(list(absdif = c(0.01, 0.01, 0.01, 0.01, 0.01, 0.01,

The code I am using to plot this data is:

ggplot(sum.qmerge) geom_dotplot(aes(x = landscape, y = absdif),dotsize=0.5,binwidth = 0.2) 
  theme(aspect.ratio = 1) 
  xlab("Landscape Type") 
  ylab("Absolute Difference")

I have tried adding the aesthetic function to both ggplot() and geom_dotplot() but I keep receiving the error. What is the solution? Many thanks.

CodePudding user response：

The plot will run if you remove y = absdif from your code. However, you may not find the resulting plot particularly exciting! Are you sure a dotplot is what you want? It's hard to know what you wanted to show without knowing more, but perhaps a bar chart would be more appropriate?

ggplot(sum.qmerge)   geom_bar(aes(x = landscape, fill = as.factor(absdif)))

CodePudding user response：

You can get the dotplot by adjusting the binaxis and stackdir options:

library(tidyverse)
