How can I plot variable count on the y axis using ggbarplot function in the ggpubr package?-CodePudding

I have a data frame df with two-factor variables. I used ggplot2 to make a barplot:

library(ggplot2)

df <- data.frame(x = factor(c("2", "1", "1", "5", "3", "2", "4", "1", "5", "3")),
                 group = factor(c("one", "two", "two", "two", "one", "two", "one", 
                 "one", "two", "two"))
                 )

ggplot(df, aes(x = x))  
  geom_bar(aes(fill = group))

I want to make the exact same barplot using the ggbarplot function from the ggpubr package, but arguments for both x and y are required.

library(ggpubr)

ggbarplot(df,
          x = "x", y = "", fill = "group", color = "group")

How can I get count of x on the y axis as I was able to do using ggplot2?

I imagine this is relatively simple but I just can't figure it out - thanks!

Unfortunately, this is not possible without creating a column with the count. What you can do is use count from dplyr like this:

library(ggplot2)

df <- data.frame(x = factor(c("2", "1", "1", "5", "3", "2", "4", "1", "5", "3")),
                 group = factor(c("one", "two", "two", "two", "one", "two", "one", 
                                  "one", "two", "two"))
)

ggplot(df, aes(x = x))  
  geom_bar(aes(fill = group))

library(ggpubr)
library(dplyr)
df %>%
  count(group, x) %>%
  ggbarplot(., 
          x = "x", 
          y = "n", 
          fill = "group", 
          color = "group",
          xlab = "count")

As you can see, it has the same result.

To remove legend:

library(ggpubr)
library(dplyr)
df %>%
  count(group, x) %>%
  ggbarplot(., 
          x = "x", 
          y = "n", 
          fill = "group", 
          color = "group",
          xlab = "count")  
theme(legend.position = "none")
