update.pulsar: Update a pulsar call

In pulsar: Parallel Utilities for Lambda Selection along a Regularization Path

Update a pulsar call

Description

Update a pulsar model with new or altered arguments. It does this by extracting the call stored in the object, updating the call and (by default) evaluating it in the environment of the original pulsar call.

Usage

## S3 method for class 'pulsar'
update(object, ..., evaluate = TRUE)

Arguments

object	a n existing pulsar or batch.pulsar object
...	arguments to pulsar to update
evaluate	Flag to evaluate the function. If FALSE, the updated call is returned without evaluation

Details

The update call is evaluated in the environment specified by the pulsar or batch.pulsar object, so if any variables were used for arguments to the original call, unless they are purposefully updated, should not be altered. For example, if the variable for the original data is reassigned, the output of update will not be on the original dataset.

Value

If evaluate = TRUE, the fitted object - the same output as pulsar or batch.pulsar. Otherwise, the updated call.

Examples

## Not run: p <- 40 ; n <- 1200
dat   <- huge.generator(n, p, "hub", verbose=FALSE, v=.1, u=.3)
lams  <- getLamPath(getMaxCov(dat$data), .01, len=20)

## Run pulsar with huge
hugeargs <- list(lambda=lams, verbose=FALSE)
out.p <- pulsar(dat$data, fun=huge::huge, fargs=hugeargs,
                rep.num=20, criterion='stars')

## update call, adding bounds
out.b <- update(out.p, lb.stars=TRUE, ub.stars=TRUE)

## End(Not run)
