# R Bar Charts


# Bar Charts
# Use the barplot() function to draw a vertical bar chart
# x-axis values
x <- c("A", "B", "C", "D")

# y-axis values
y <- c(2, 4, 6, 8)

barplot(y, names.arg = x)



# Bar Color
# Use the col parameter to change the color of the bars
x <- c("A", "B", "C", "D")
y <- c(2, 4, 6, 8)

barplot(y, names.arg = x, col = "red")



# Density / Bar Texture
# To change the bar texture, use the density parameter
x <- c("A", "B", "C", "D")
y <- c(2, 4, 6, 8)

barplot(y, names.arg = x, density = 10)



# Bar Width
# Use the width parameter to change the width of the bars
x <- c("A", "B", "C", "D")
y <- c(2, 4, 6, 8)



# Horizontal Bars
# If you want the bars to be displayed horizontally instead of vertically, use horiz=TRUE
x <- c("A", "B", "C", "D")
y <- c(2, 4, 6, 8)

barplot(y, names.arg = x, horiz = TRUE)
