主标题和副标题在多面 ggplot2 中不正确 plot

Question

I am trying to plot a faceted gauge chart. The plot is OK except that the title and subtitle print in the first facet panel instead of the top. How can I correct that, I have tried "inherit.aes = FALSE" but I am getting:

 unused argument (inherit.aes = FALSE)

Here is the data and code that I have tried. Much thanks in advancef

library(showtext) 
library(tidyverse)


# add fonts

font_add_google(name = "Bebas Neue", family = "Bebas Neue")
showtext_auto()

#data 
 df <- data.frame(matrix(nrow=5, ncol = 2))

names(df) <- c("variable", "percentage")
df$variable <- c("Carbohydrates", "Warming", "NGTnotPresent", "DrainNotPresent", "DrEaMing")
df$percentage <- c(0.67,0.33,0.86,0.78,0.58)

df <- df %>% mutate(group=ifelse(percentage <0.6, "red",
 ifelse(percentage>=0.6 & percentage<0.8, "orange","green")),
 label=paste0(percentage*100, "%"),
 title=dplyr::recode(variable, `Carbohydrates`="Preoperative\ncarbohydrate loading",
 `Warming`="Intraoperative\nwarming",
 `NGTnotPresent`="\nPatients without a\nnasogastric tube\non arrival in recovery",
 `DrainNotPresent`="\nPatients without an\nabdominal drain\non arrival in recovery",
 `DrEaMing`="Patients DrEaMing on\npostoperative day 1"))

title <- "pomVLAD risk-adjustment model"
subtitle <- 'The model is being used to produce a variable life-adjusted display plot for each of the 10 pilot hospitals showing their expected against observed postoperative morbidity outcomes' %>% 
      str_wrap(width = 50)
caption <- "Data: pomVLAD | Viz: @stepminer2"

The answer is simple: you are wraping the caption text to a width of 50 characters with str_wrap(width = 50) . Change 50 into a bigger number.
