Code issue in R - Error in 'geom_point()'

[richydud]

My code chunk runs on markdown, but when I try to knit my markdown it gives me this error:

Error in geom_point():
! Problem while setting up geom.
Error occurred in the 1st layer.
Caused by error in compute_geom_1():
! geom_point() requires the following missing aesthetics: y
Backtrace:

1. rmarkdown::render(...)
2. knitr::knit(knit_input, knit_output, envir = envir, quiet = quiet)
3. knitr:::process_file(text, output)
4. knitr:::process_group.block(group)

10. ggplot2 (local) compute_geom_1(..., self = self)
    Execution halted

Here is my code:

if (!require("ggplot2")) install.packages("ggplot2")
library(ggplot2)

aa_score <- (ghana_map$"Aedes aegypti score")

ggplot(ghana_map, aes(x = HDI, y = aa_score, color = Water_access)) +
  geom_point(size = 1, stroke = 0.5) +  
  geom_hline(yintercept = 0, color = "black", linetype = "solid") +  
  geom_vline(xintercept = 0.5, color = "black", linetype = "solid") +  
  labs(x = "HDI", y = "Aedes Aegypti Score", color = "Water Access") +
  theme_minimal() +
  theme(
    axis.title.x = element_text(face = "bold"),  
    axis.title.y = element_text(face = "bold"),
    legend.position = "top",  
    legend.direction = "horizontal",  
    legend.box.background = element_rect(color = "black", size = 0.5), 
    legend.title.align = 0.5, 
    legend.text.align = 0.5  
  ) +
  guides(color = guide_legend(override.aes = list(fill = "white")))

Are you in a position to share data? It'll be difficult to troubleshoot without more context.
