After migrating R from 3.2.3 to 3.4.3 predict function throwing an error #11

Closed rmodepalli closed 6 years ago

rmodepalli commented 6 years ago

Earlier we are running our model on R version 3.2.3 which use C50 package(version 0.1.0.24) and working as expected. Now we migrated to R 3.4.3 with C50 (version 0.1.1) . With this upgrade we are getting following error.

Error: *** line 2 of undefined.cases': bad value of(0' for attribute `contrib_bucket'

We are getting above error for below function call.

clean_data$segment <- predict(segmentationModel, clean_data, type='class')

Is there any known bug with latest version? Thanks in advance for looking at this issue.

Please find below the steps to reproduce and required dataframe, model is attached. Reproduce.zip

Steps:

library(C50) cleandata <- readRDS(file="cleandata.Rda") load('segmentationModel.rdata') predict(segmentationModel, cleandata, type='class')

And also I am not able to install C50 package on Ubuntu. Is C50 will support on Ubuntu?

topepo commented 6 years ago

The bug was in Cubist and should work now.

And also I am not able to install C50 package on Ubuntu. Is C50 will support on Ubuntu?

Can you elaborate?

rmodepalli commented 6 years ago

Thanks topepo for the fix. Do I need reinstall the package to get the fix? Regarding your question I am trying to install C50 on Ubuntu OS. I am not able to install on Ubuntu 16.0.

topepo commented 6 years ago

You should reinstall C50 and Cubist from GitHub. If you can't let me know and I can get the windows binaries built (if that's what you need).

I am not able to install on Ubuntu 16.0.

More details would help. Can you send the log of those installations?

rmodepalli commented 6 years ago

Thanks topepo. Now after downloading the C50 and Cubist from GitHub its working. I tried Ubuntu installation on new machine and its working. When can this fix will be available in CRAN?

topepo commented 6 years ago

I have a few more things to fix in C50 I would estimate it will be there within the month.
