bootstrap_p issue, could not find function "get_n" #53

Closed AnaCG closed 9 years ago

AnaCG commented 9 years ago

Greetings. I am working with a very large dataset, in the form of dataframe (4635810 elements). The error is at the end of the message, I hope you have had this issue before and can tell me what I am doing wrong. It is really complicated to provide the dataset, never the less these are the commands I am applying: alldeg<-the 4635810 elements deg_pl<-displ$new(alldeg) est<-estimate_xmin(deg_pl) deg_pl$xmin<-est

print("KS statistic for power law distribution") print(est$KS)

bs<-bootstrap_p(deg_pl)

At this point, I get the following error: Error in checkForRemoteErrors(val) : one node produced an error: could not find function "get_n" Calls: bootstrap_p ... clusterApply -> staticClusterApply -> checkForRemoteErrors

Ok. I think I know what's wrong. I'll fix on Monday.

I couldn't reproduce your error, but I think I may still be able to fix it. Would you try out the fix and let me know. Thanks

AnaCG commented 9 years ago

Ok thank you, I'll let you know if this helped!

Hey! so I am still getting the error, do I need any sort of special permissions for this? Because I am trying to run this code on a cluster, and when trying to do so on my own computer it required administrative permissions.

To double check I presume you used the github version

Hey! sorry but I could not solve the error, I have a smaller 685KB dataset that I can email to you for you to replicate the error.
