Can I tell the R plyr package to work in parallel by default?
default, parallel-processing, plyr, r
Solution
library(Defaults)
setDefaults(llply, .parallel=TRUE)
You'd have to `setDefaults` on every function for which you want to change the default formals. You can put this in your .Rprofile if you like.
You can also mess with the formals directly. e.g. `formals(llply)$.parallel <- TRUE` should work.
Problem
I'm doing some analysis something like this: ``` library(plyr) input.files <- c("file1.txt", "file2.txt", "file3.txt") input.data <- llply(input.files, load.file, .parallel=TRUE) step.one.results <- llply(input.data, step.one, .parallel=TRUE) step.two.results <- llply(step.one.results, step.two, .parallel=TRUE) ... step.N.results <- llply(`step.N-1.results`, step.N, .parallel=TRUE) ... ``` Is there any way to make all the plyr functions parallel by default, so I don't always have to specify `.parallel=TRUE` for each step?
