How to close additional R sessions when parallel computing is completed using doFuture package?
问题
我正在尝试使用doFuture包进行并行计算。以下是该包文档中的代码。
library(doFuture)
plan(multisession)
cutoff <- 0.10
y <- foreach(x = mtcars) %dofuture% {
mean(x, trim = cutoff)
}
names(y) <- colnames(mtcars)
当计算完成时，用于并行计算的额外R会话没有关闭。当我使用doParallel包时，我使用以下代码创建集群：
cl <- makeCluster(cores)
registerDoParallel(cl)
并使用以下代码停止集群：
closeCluster(cl)
在使用doFuture包时，如何关闭这些R会话呢？
英文:
I'm trying to use doFuture package for parallel computing. Here is the code from the document of the package.
library(doFuture)
plan(multisession)
cutoff <- 0.10
y <- foreach(x = mtcars) %dofuture% {
mean(x, trim = cutoff)
}
names(y) <- colnames(mtcars)
When the computing is completed, the additional R sessions for parallel computing are not closed. When I use doParallel package, I use the following to make cluster
cl <- makeCluster(cores)
registerDoParallel(cl)
and use the following code to stop cluster.
closeCluster(cl)
How do I close these R sessions when using the doFuture package?

将计划设置为sequential()将关闭额外的R会话。
英文:
Setting the plan to sequential() will close the extra R sessions.
plan(sequential)
