dcsvm (version 0.0.1)

plot.dcsvm: Plot Coefficients for Sparse Density-Convoluted SVM

Description

Plots the solution paths as a coefficient profile plot for a fitted dcsvm model.

Usage

# S3 method for dcsvm
plot(x, xvar = c("norm", "lambda"), color = FALSE, label = FALSE, ...)

Value

No return value, only called for plots.

Arguments

x

A fitted dcsvm model.

xvar

Specifies the X-axis. If xvar == "norm", plots against the L1-norm of the coefficients; if xvar == "lambda", plots against the log-lambda sequence.

color

If TRUE, plots the curves with rainbow colors; otherwise, with gray colors (default).

label

If TRUE, labels the curves with variable sequence numbers. Default is FALSE.

...

Other graphical parameters to plot.

Details

Plot Coefficients for Sparse Density-Convoluted SVM

# Plots against the L1-norm of the coefficients
plot(fit)
# Plots against the log-lambda sequence
plot(fit, xvar="lambda", label=TRUE)
# Plots with colors
plot(fit, color=TRUE)
