Plot function

Description

Plot function for objects of class logilasso, predlogilasso and predlogispez.

Usage

## S3 method for class 'logilasso':
plot(x, grenze = 0,...)
## S3 method for class 'predlogilasso':
plot(x, grenze = 0, ...)
## S3 method for class 'predlogispez':
plot(x, ...)

Arguments

x An object of class logilasso, predlogilasso or predlogispez.
grenze Up to which fraction of the maximal absolute component of beta, the individual components are treated as zero. If 1, then all beta components are treated as zero, if 0, then all components which do not equal zero are treated as nonzeros.
... Additional arguments to the plot function.

Details

For objects of class predlogispez the trajectories of the components of the beta vectors are plotted against the lambdas. For objects of class predlogilasso the corresponding undirected graphical model (CIG) is plotted.

For objects of the class logilasso, first the predict() function is applied and the resulting object of either class predlogispez or predlogilasso is plotted as described above.

Examples

library(gRbase)
data(reinis)

fit <- logilasso(reinis,lambdainit=1,lambdamin=0.1)
plot(fit)

fitcv <- logilasso(reinis,lambdainit=1,lambdamin=0.1,cvfold=3)
plot(fitcv)

levellogi <- levelcv(reinis,lambdainit=1,lambdamin=0.1,to.which.int=3,cvfold=3)
plot(levellogi)

pred <- predict(fit,lambda=0.3)
plot(pred)
