blapply {polmineR}

apply a function over a list or bundle

Description

Very similar to lapply, but applicable to bundle-objects, in particular. The purpose of the method is to supply a uniform und convenient parallel backend for the polmineR package. In particular, progress bars are supported (the naming of the method is derived from bla bla).

Usage

blapply(x, ...)

## S4 method for signature 'list'
blapply(x, f, mc = TRUE, progress = TRUE, verbose = FALSE, ...)

## S4 method for signature 'vector'
blapply(x, f, mc = FALSE, progress = TRUE, verbose = FALSE, ...)

## S4 method for signature 'bundle'
blapply(x, f, mc = FALSE, progress = TRUE, verbose = FALSE, ...)

Arguments

x

a list or a bundle object

...

further parameters

f

a function that can be applied to each object contained in the bundle, note that it should swallow the parameters mc, verbose and progress (use ... to catch these params )

mc

logical, whether to use multicore - if TRUE, the number of cores will be taken from the polmineR-options

progress

logical, whether to display progress bar

verbose

logical, whether to print intermediate messages

Examples

use("polmineR")
bt <- partition("GERMAPARLMINI", date = ".*", regex=TRUE)
speeches <- as.speeches(bt, s_attribute_date = "date", s_attribute_name = "speaker")
foo <- blapply(speeches, function(x, ...) slot(x, "cpos"))
