plot.linearcl: Plot coefficients for SVM with linear kernel
Description
The function visualize the contribution of each feature variable by plotting a selected subset of standardized coefficients from SVM with linear kernel, the coefficients are standardized dividing by the L2 norm of the subvector.
Usage
# S3 method for linearcl
plot(x, index = NULL, names = NULL,
ylab = "std coefficients", xlab = "", col = "gray",...)
Arguments
x
a model with class 'linearcl'.
index
is the vector of indices of variables to plot.
names
is the vector of names of each variables to appear in the plot. If not specified, the names would be V1-Vp.
ylab
The label for the y axis. Defalt is "std coefficients".
xlab
The label for the x axis.
col
color to fill the bars in the plot.
