Rstudio调用gamlss包绘图

出图的线条大小和颜色，坐标轴名称如何调整呢？

代码和绘图如下：

> library("gamlss")

> data("abdom")

> plot(y ~ x, data = abdom, col = "blue", xlab = "age", ylab = "circumference")

> abd0 <- gamlss(y ~ poly(x, 3), data = abdom, family = NO)

> summary(abd0)

> abd00 <- gamlss(y ~ x + I(x^2) + I(x^3), data = abdom, family = NO)

> summary(abd00)

> abd1 <- gamlss(y ~ cs(x, df = 3), data = abdom, family = NO)

> fitted(abd1, "sigma")[1]

> predict(abd1, what = "sigma", type = "response")[1]

> abd2 <- gamlss(y ~ cs(x, 3), sigma.formula = ~cs(x, 3), data = abdom, family = NO)

> plot(abd2)

 wp(abd2)
