错误消息“：美学必须是长度1或与数据相同（456）：label”

Question

I am a newbie to R. I am trying to show two ggplots on one screen using the patchwork package with the following code and I am getting the above error. I have tried resolving the error unsuccessfully, I can resolve the error for "fill" aesthetic only. Kindly assist.

library(ggridges)
library(patchwork)
library(viridis)
library(hrbrthemes)
library(ggplot2)
library(dplyr)
library(ggpubr)
library(gridExtra)
theme_set(theme_bw())
theme_set(theme_pubr())

file <- ("c:/PMS/DHA&PPTabletsClean.csv")
data <- read.csv(file, header=TRUE, stringsAsFactors=FALSE, fileEncoding="latin1")
data <- filter(data, data$ActiveIngredient == "Dihydroartemisinin")


data <- data %>%
  group_by(Manufacturer) %>%
  mutate(OutOfSpec = ifelse(Assayperc < 0.90 | Assayperc > 1.10, FailureReason, ""))%>%




# is_oos <- function (x) {
#   data$Assayperc < 0.90 | data$Assayperc > 1.10
# }
# 
# data <- data %>%
#   mutate(OutOfSpec = ifelse(is_oos(Assay), BatchNumber, "")) %>%
   # view(data)

# library(data.table)
  # setDT(data)
  # 
  # data[, OutOfSpec := fifelse(Assay < 90 | Assay > 110, BatchNumber, ""),

data.frame(data)

Kindly assist with resolving error message

Answer 1

Removing the following code lines from both codes works:

geom_text(aes(label = data$OutOfSpec), position = position_dodge(0.75),vjust=-0.8,size =5, color ="navy")

However, the best way to retain the label is to put the label under the aesthetics of the ggplot.
