EQO_ga no applicable sendData error

[AroneyS]

Hi @Xiaoyu2425,

I've installed mEQO using devtools into R version 4.2.3. It seems to install fine and I can access Microbiome and trait, but when I run EQO_ga("c",Microbiome,trait,maxIter=100), I get the following error:

Error in UseMethod("sendData") : 
  no applicable method for 'sendData' applied to an object of class "NULL"

Any ideas?

Hi! I haven't seen this error before, but it seems to be related to parallel computing. Could you please try to test "parallel=F" and see what happens?

[AroneyS]

Thanks for the prompt reply! Unfortunately I still get the same error.

r$> parallel=F

r$> EQO_ga("c",Microbiome,trait,maxIter=100)
Error in UseMethod("sendData") : 
  no applicable method for 'sendData' applied to an object of class "NULL"

Oh sorry I mean EQO_ga("c",Microbiome,trait,maxIter=100,parallel="F")

[AroneyS]

Oh right, haha. I get:

r$> EQO_ga("c",Microbiome,trait,maxIter=100,parallel="F")
Error in startParallel(parallel) : 
  Only 'snow' and 'multicore' clusters allowed!

If I change it to FALSE, it seems to work:

r$> EQO_ga("c",Microbiome,trait,maxIter=100,parallel=FALSE)

ah, sorry, I did mean FALSE... Ok cool, thank you for sharing with us this information. It seems that doParallel R package leveraged for genetic algorithm does not work well on your computer, which might take some time to figure out why. For the time being perhaps just run it without parallel :)
