Bar Plot (base)

barplot(recaptable$IPVs, 
        main="IP Visits in the Last 12 months",
        xlab = "PPL",
        ylab = "IP Visits", col = 'lightgray')

Final result: Bar Plot base

Bar Plot with ggplot

# ggplot2 plot with modified x-axis labels
# ggplot: With x-axis labels
ggplot(recaptable, aes(PPL, IPVs)) +    
  geom_bar(stat = "identity", fill = "#990000") +
  theme(axis.text.x = element_text(angle = 90, size = 10)) + 
  ggtitle("IP Visits in the Last 12 months")

Final result: Bar Plot using ggplot
