Тип линии графика lty

В R тип линии графика можно указать с помощью аргумента lty. Для этого можно использовать текстовые значения («blank», «solid», «dashed», «dotted», «dotdash», «longdash», «twodash») или числа (0, 1, 2, 3, 4, 5, 6)

# Sample data
x <- 1:10
y <- x

# Basic plot with different line types
plot(x, y, type = "n", main = "Line Types with plot()")

# Add lines with different types
lines(x, y, lty = 1, col = "black", lwd = 2) # Solid line
lines(x, y + 1, lty = 2, col = "red", lwd = 2) # Dashed line
lines(x, y + 2, lty = 3, col = "green", lwd = 2) # Dotted line
lines(x, y + 3, lty = 4, col = "blue", lwd = 2) # Dotdash line
lines(x, y + 4, lty = 5, col = "purple", lwd = 2) # Longdash line
lines(x, y + 5, lty = 6, col = "brown", lwd = 2) # Twodash line

# Add legend
legend("bottomright", legend = c("Solid", "Dashed", "Dotted", "Dotdash", "Longdash", 
 "Twodash"),
 lty = 1:6, col = c("black", "red", "green", "blue", "purple", "brown"), lwd = 2)
