Add axis text above horizontal geom_bars; text alignment to the left

Question

I would like to put the text axis above the corresponding horizontal stripes on the chart ggplot2. Below, as I understand it, with a subsequent schedule. Data is at the bottom of this question.

My questions , apart from the ubiquitous “which code is better to achieve the goal,” are (1) instead of manually entering a rectangle and text fields, how R can put them algorithmically, (2) how R can move text in rectangles to the far left (I tried with the calculation midpoint depending on the number of characters in the text, but that doesn't work)?

To plot, I created a sequence variable instead of struggling with as.numeric(as.character(risks).

ggplot(plotpg19, aes(x = sequence, y = scores)) +
  geom_bar(stat = "identity", width = 0.4) +
  coord_flip() +
  labs(x = "", y = "") +
  theme_bw() +
  theme(axis.text.y = element_blank(), axis.ticks.y = element_blank()) +
  geom_rect(data=plotpg19, aes(xmin= seq(1.5, 8.5, 1), 
                               xmax= seq(1.8, 8.8, 1), ymin=0, ymax=30), fill = "white") +
  geom_text(data=plotpg19, aes(x=seq(1.6, 8.6, 1), y= nchar(as.character(risks))/2, label=risks, size = 5, show_guide = FALSE)) +
  guides(size = FALSE)

.

plotpg19 <- structure(list(risks = structure(c(8L, 7L, 6L, 5L, 4L, 3L, 2L, 
1L), .Label = c("Other", "Third parties/associates acting on our behalf", 
"Rogue employees", "Lack of understanding by top executives", 
"Lack of anti-bribery/corruption training or awareness within the business", 
"Geographic locations in which the company operates", "Industries/sector(s) in which the company operates", 
"Inadequate resources for anti-bribery/corruption compliance activities"
), class = "factor"), scores = c(15, 28, 71, 16, 5, 48, 55, 2
), sequence = 1:8), .Names = c("risks", "scores", "sequence"), class = "data.frame", row.names = c(NA, 
-8L))

. geom_text geom_rect

Answer 1

, geom_rect. y=0 aes of geom_text hjust=0 ( y) . x, :

library(dplyr)
plotpg19 <- mutate(plotpg19, xtext = sequence + 0.55)

library(ggplot2)
ggplot(plotpg19, aes(x = sequence, y = scores)) +
  geom_bar(stat = "identity", width = 0.4) +
  coord_flip() +
  labs(x = "", y = "") +
  theme_bw() +
  theme(axis.text.y = element_blank(), axis.ticks.y = element_blank()) +
  geom_text(data = plotpg19,
            aes(x = xtext, y = 0, label = risks, size = 5, show_guide = FALSE),
            hjust = 0, vjust = 1) +
  guides(size = FALSE)
