plotpath function

Plotting the LASSO path

Plotting the LASSO path

Plotting a LASSO path fitted using penalized with steps > 1.

plotpath(object, labelsize = 0.6, standardize = FALSE, ...)

Arguments

  • object: A list of link{penfit} objects calculated for the same data but different lambda1 values. This object can be created using the link{penalized} function using the steps argument.
  • labelsize: Sets the size of the variable labels in the plot. Set to zero for no variable labels.
  • standardize: If TRUE, plots the regression coefficients for the covariates standardize to unit second central moment. See penalized for details on standardization. Note that the standardization in plotpath can also be used if standarization was not used in penalized.
  • ...: Any other arguments will be forwarded to the plot function.

Examples

data(nki70) # Fit the model with the steps argument and plot pen <- penalized(Surv(time, event), penalized = nki70[,8:77], data = nki70, lambda1=1, steps = 20) plotpath(pen)
