Plot by lines of a data frame in R

Question

I have a table looking like this

         hashtag  Daily_Freq men women 
          #a          10       6     4  
          #b          15       5    10   
          #c          20       8    12  

I want to plot for each data frame line, i.e. for each hashtag, the frequency of men and women. In this case I would want to plot 3 barplots, each one with two columns - one for men and anoher for women frequencies. How can I do this?

Answer 1

One solution is using gather and ggplot2 as:

#data
df <- read.table(text = "hashtag  Daily_Freq men women 
'#a'          10       6     4  
'#b'          15       5    10   
'#c'          20       8    12", header = T, stringsAsFactors = F)

library(tidyverse)
df <- df %>% select(-Daily_Freq) %>%
         gather(key = Gender, value, -hashtag)

library(ggplot2)
ggplot(df, aes(x=hashtag, y=value, fill=Gender)) +
geom_bar(stat='identity', position='dodge')

Option #2

ggplot(df, aes(x=Gender, y=value)) +
  geom_bar(stat='identity', position='dodge') + facet_grid(~ hashtag)
