R Bars

bar charts are created using the barplot() function.

Syntax barplot(values, names.arg = categories)

# Example data
categories <- c("Category A", "Category B", "Category C", "Category D")
values <- c(30, 20, 15, 35)

# Create a bar chart
barplot(values, names.arg = categories, main = "Bar Chart", xlab = "Categories", ylab = "Values", col = "skyblue")

Use of attributes

We can use attributes to make a difference.

1. names.arg - A vector of names to be plotted below each bar.
2. main - The main title of the plot.
3. xlab and ylab - Labels for the x-axis and y-axis.
4. col - Color of the bars.

# Customized bar chart
colors <- c("red", "green", "blue", "yellow")

barplot(values, names.arg = categories, main = "Customized Bar Chart", xlab = "Categories", ylab = "Values", col = colors)
