[R] specific package to laply

[Benjamin]

Hi,

I have a batch jobs problem for parallel code without sudo.  When I try to
send a package to the different nodes, as follows:

.libPaths( c(.libPaths(),
             "/my/first/library",
             "/my/second/library")
          )
library(foreach)
library(iterators)
library(parallel)
library(doParallel)
library(rvest)
cl <- makeCluster(detectCores())
registerDoParallel(cl)
sites <- paste0("https://www.site",1:2,".com")

html0 <- foreach(i=sites,.packages='rvest') %dopar% html(i)


I get the following output:

Error in e$fun(obj, substitute(ex), parent.frame(), e$data) :
  worker initialization failed: there is no package called ‘rvest’
Calls: %dopar% -> <Anonymous>

Presumably, I need a way to export my .libPaths() to the nodes.  Any
suggestions?

Thanks,
Benjamin
