plot.grplasso {grplasso} | R Documentation |
Plots the solution path of a grplasso object
Description
Plots the solution path of a grplasso
object.
Usage
## S3 method for class 'grplasso':
plot(x, type = "coefficients", col = NULL, ...)
Arguments
x |
a grplasso object |
type |
type = "coefficients" plots coefficients with respect to
the input variables, even if standardize = TRUE is used in
grplasso . |
col |
a vector indicating the color of the different group
paths. The length should equal the number of groups. The same
ordering as in the vector index is used with the exception
that the unpenalized coefficients are grouped at the beginning of
the vector. |
... |
other parameters to be passed to the plotting functions. |
Examples
data(splice)
contr <- list(Pos.1 = "contr.sum", Pos.2 = "contr.sum")
lambda <- lambdamax(y ~ Pos.1 * Pos.2, data = splice, model = LogReg(),
contrasts = contr, standardize = TRUE) * 0.8^(0:8)
fit <- grplasso(y ~ Pos.1 * Pos.2, data = splice, model = LogReg(),
lambda = lambda, contrasts = contr, standardize = TRUE,
control = grpl.control(trace = 0, inner.loops = 0,
update.every = 1, update.hess = "lambda"))
plot(fit, log = "x")
