cannot add pie chart in to a graphic

Question

I want a pie chart instead of a table

method <- dataframe (stringsFactors=FALSE,method=c("violent","nonviolent"),accessiblepeople = (20000,60000)

usage <- dataframe (stringsFactors=FALSE,method=c("violent","nonviolent"),usage = (30%,70%)

ggplot(method, aes(x=method,y=accessiblepeople)+geom_bar(stat="identity")+ggtitle("")+ggpiechart())

Problem add piechart seems not working

Never heard of `ggpiechart`. Where is that from? + I am afraid your code is not working (missing parenthesis etc.). Check this post on how to make a pie chart with ggplot: https://stackoverflow.com/questions/47238098/plotting-pie-charts-in-ggplot2 — harre, Aug 04 '22 at 09:55

You can use plot_grid from the package cowplot to place plots next to each other. I also specified a few features with theme() to remove the gray background so the final plot looks more cohesive.

library(tidyverse)
library(cowplot)

method <- data.frame(method = c("violent", "nonviolent"), 
                     accessiblepeople = c(20000,60000))

bar <- ggplot(method, aes(x = method, y = accessiblepeople, fill = method)) + 
  geom_bar(stat = "identity") + ggtitle("") + 
  theme_bw() +
  theme(legend.position = "none") + 
  theme(panel.border = element_blank(), 
        panel.grid.major = element_blank(),
        panel.grid.minor = element_blank(), 
        axis.line = element_line(color = "black"))

pie <- ggplot(method_df, aes(x="", y=accessiblepeople, fill=method)) +
  geom_bar(stat="identity", width=1) +
  coord_polar("y", start=0) + theme_void()

plot_grid(bar, pie)
