Here we introduce plots & charts in R, with a table of several plots & charts, and pages on graphical parameters and plot designs.

1 Table of Various Plots & Charts in R

The following are examples of some plot & charts in R, with more details in the linked pages on them.

Table of Plots and Charts in R
Type Example
Histogram Histdata = c(164, 152, 144, 128, 146, 194, 84, 196, 113, 124)
hist(Histdata, main = "Histogram")
Density Plots Densitydata = c(552, 645, 55, 641, 662, 188, 87, 198, 223, 588)
den = density(Densitydata)
plot(den, main = "Density Histogram")
Scatter Plots Xdata = c(164, 153, 144, 127, 147, 194, 86, 191, 113, 123)
Ydata = c(184, 147, 159, 102, 136, 108, 153, 191, 172, 197)
plot(Xdata, Ydata, main = "Scatter Plot")
Bar Charts/
Bar Plots 		Q1 = c(96.7, 129.3, 199.5, 159.4, 103.4)
Year = c("1992", "1993", "1994", "1995", "1996")
barplot(Q1 ~ Year, main = "Bar Plot")
Box Plots Boxdata = c(27, 31, 55, 24, 72, 53, 54, 27, 68, 19)
boxplot(Boxdata, main = "Box Plot")
Line Charts Linedata = c(151, 142, 147, 122, 145, 198, 84, 190, 121, 132)
plot(Linedata, type = "l", main = "Line Chart")
Pie Charts Grade = c(Year1 = 117, Year2 = 112, Year3 = 201, Year4 = 280)
pie(Grade, main = "Pie Chart")
Stem-and-Leaf Stemdata = c(76, 77, 73, 65, 54, 68, 63, 54, 66, 64,
73, 67, 68, 60, 56, 67, 64, 54, 69, 63)
stem(Stemdata)
Plotting Curves equation = function(x){4*x^2 - x + 3}
curve(equation, -3, 6, main = "Plot of Curve")
plot(equation, -3, 6, main = "Plot of Curve")
Dot Plots Food = c(24.3, 45.3, 57.4, 72.4, 85.6)
Books = c(9.7, 12.4, 28.0, 37.2, 45.3)
Expense = as.matrix(cbind(Food, Books))
rownames(Expense) = c("1970", "1975", "1980", "1985", "1990")
dotchart(Expense, main = "Dot Plot")


2 Pages on Graphical Parameters & Plot Designs in R

For details on applying graphical parameters, see the following pages:


Examples of Common Graphical Parameters for Colors and Fonts:

Summary of Some Graphical Parameters in R
Region Text Font Size Font Type Color
General for no plot: type = "n" cex font col
Main main cex.main font.main col.main
Labels xlab & ylab cex.lab font.lab col.lab
Axis limits: xlim & ylim
no axis: xaxt = "n", yaxt = "n"		 cex.axis font.axis col.axis
Sub-titles sub cex.sub font.sub col.sub
Border border
Background bg
Foreground fg


Illustration Using a Histogram: 

histdata = rnorm(1000)
hist(histdata,
     main = "Graphical Parameters Plots & Charts Example",
     xlab = "X Label Text",
     ylab = "Y Label Text",
     sub = "The Plot Sub",
     cex = 1, cex.main = 1.2, cex.lab = 1.2,
     cex.axis = 0.7, cex.sub = 0.8,
     font = 1, font.main = 2, font.lab = 3,
     font.axis = 4, font.sub = 2,
     col = "turquoise", col.main = "brown",
     col.lab = "cyan", col.axis = "gold",
     col.sub = "blue",
     border = "red", bg = "green", fg = "orange")
