batchtools_local | R Documentation |
A batchtools local future is an synchronous uniprocess future that will be evaluated in a background R session. A batchtools interactive future is an synchronous uniprocess future that will be evaluated in the current R session (and variables will be assigned to the calling environment rather than to a local one). Both types of futures will block until the futures are resolved.

batchtools local futures rely on the batchtools backend set up by
batchtools::makeClusterFunctionsInteractive(external = TRUE)
and batchtools interactive futures on the one set up by
batchtools::makeClusterFunctionsInteractive()
.
These are supported by all operating systems.
An alternative to batchtools local futures is to use
cluster futures of the future
package with a single local background session, i.e.
plan(cluster, workers = "localhost")
.
An alternative to batchtools interactive futures is to use
plan(sequential, split = TRUE)
futures of the future package.

## Use local batchtools futures plan(batchtools_local) ## A global variable a <- 1 ## Create explicit future f <- future({ b <- 3 c <- 2 a * b * c }) v <- value(f) print(v) ## Create implicit future v %<-% { b <- 3 c <- 2 a * b * c } print(v)
