GrĂ¡ficos con la funciĂ³n plot
Ejemplo 1: grĂ¡fico de dispersiĂ³n
x = c(2,6,3,6.3,1,4,6.7,3,4.3,5)
y = c(1,7.3,4,7,4,6,6.9,2,7,4)
plot(x,y)
Ejemplo 2: grĂ¡fico de una funciĂ³n \(f(x)=\sqrt{x}+3\)
f <- function(x){sqrt(x)+3}
plot(f,col="green", main="GrĂ¡fica de una funciĂ³n f(x)")
Ejemplo 3: Elementos adicionales en un grĂ¡fico
f <- function(x){x^2 -2*x + sqrt(abs(x))}
plot(f, xlim = c(-3,3))
points(0,0, pch = 19)
points(-3:3, (-3:3)^2, col = "blue")
abline(2,3, lty = "dashed", col = "red")
abline(v = 2, lty = "dotted", col = "green")
abline(h = 5, lty = "dotdash", col = "gray")
Ejemplo 4: GrĂ¡fico de varias funciones al mismo tiempo
f <- function(x){x^2}
plot(f, xlim = c(-3,3), ylim = c(-10,10))
points(-3:3, f(-3:3), pch = 19)
lines(-3:3, f(-3:3), lwd = 2, lty = "dotted", col = "red")
curve(x^3, lty = "dashed", col = "blue", add = TRUE)
curve(x^4, lty = "dashed", col = "orangered", add=TRUE)
legend("bottomright",
legend = c(expression(x^2), expression(x^3), expression(x^4)),
lwd = 2,
col = c("red", "blue", "orangered"),
lty = c("dotted", "dashed", "dashed"))
