Im sure this is fairly easy but im new to R. how do you plot a bar graph with the following data.
D_data <- data.frame(month=c(1,2,3,4),
A=c(22,55,66,88),
B=c(7,8,5,8),
c=c(1,2,9,10))
The bar graph as x axis as the month, y as the value of each category A, B, C. There should be 3 bars for each month.

Since you tagged this with ggplot2
, I assume you don't want a base R solution, but you can use pivot_longer()
to tidy your data and then use ggplot()
with another argument.
More importantly, you don't have enough values to make boxplots with month
and letters. However, you can make a bar plot.
library(tidyverse)
D_data %>%
pivot_longer(cols = -month) %>%
ggplot(aes(x = name, y = value, fill = name))
geom_boxplot()
D_data %>%
pivot_longer(cols = -month) %>%
ggplot(aes(x = month, y = value))
geom_bar(stat = "identity",
position = "dodge",
aes(fill = name))
