SGPR (version 0.1.2)

plot.sgp: Plots the coefficient path of an SGP object

Description

Produces a coefficient profile plot of the coefficient paths for a fitted SGP object

Usage

# S3 method for sgp
plot(x, alpha = 1, legend.pos, label = FALSE, log.l = FALSE, norm = FALSE, ...)

Value

A plot object with the coefficient path of an SGP.

Arguments

x

A object that was generated with sgp.

alpha

Tuning parameter for the alpha-blending.

legend.pos

Coordinates or keyword for positioning the legend.

label

A Boolean value that specifies whether the plot should be annotated.

log.l

A Boolean value that specifies whether the horizontal axis should be on the log scale.

norm

A Boolean value that specifies whether the norm of each group should be plotted.

...

Other parameters of underlying basic functions.

Examples

n <- 100
p <- 12
nr <- 4
g <- paste0("Group ",ceiling(1:p / nr))
X <- matrix(rnorm(n * p), n, p)
b <- c(-3:3)
y_lin <- X[, 1:length(b)] %*% b + 5 * rnorm(n)
y_log <- rbinom(n, 1, exp(y_lin) / (1 + exp(y_lin)))

lin_fit <- sgp(X, y_lin, g, type = "linear")
plot(lin_fit, legend.pos = "topright", label = TRUE)
plot(lin_fit,  label = TRUE, norm = TRUE)

log_fit <- sgp(X, y_log, g, type = "logit")
plot(log_fit, legend.pos = "topright", label = TRUE)
plot(log_fit, label = TRUE, norm = TRUE)
