in Chap 13, we hit the following error

[vkjuju]

nbTraining <- training[, c("Class", nbPredictors)] Error in [.data.frame(training, , c("Class", nbPredictors)) : undefined columns selected

any advice would be appreciated

any advice would be appreciated.

Hi, Max, our professor selected your book as our courseware, please take a look at this issue once you get a chance , Thanks... your book: Applied predictive modeling->Chap13->computing

We also found some syntax errors and solution on Chap10, we're glad to provide you our findings... please also check your email(mxkuhn@gmail.com) once available.. Regards, .jOe

There are no solutions to the chapter 13 exercises posted here. You will need to provide a lot more detail about what exactly you are doing, with what code, what versions of R and other packages, etc.

[vkjuju]

in this link: https://github.com/cran/AppliedPredictiveModeling/blob/master/inst/chapters/13_Non-Linear_Class.R from Line 357 to Line 367(error occured on Line 367):

Section 13.6 Naive Bayes

Create factor versions of some of the predictors so that they are treated as categories and not dummy variables

factors <- c("SponsorCode", "ContractValueBand", "Month", "Weekday") nbPredictors <- factorPredictors[factorPredictors %in% reducedSet] nbPredictors <- c(nbPredictors, factors)

The following code hit error message:

nbPredictors <- nbPredictors[nbPredictors != "SponsorUnk"] nbTraining <- training[, c("Class", nbPredictors)] Error in [.data.frame(training, , c("Class", nbPredictors)) : undefined columns selected

Required packages installed as follows: AppliedPredictiveModeling, caret, doMC , kernlab, klaR, lattice, latticeExtra, MASS, mda, nnet, pROC

R 3.4 on windows , Ubuntu, Mac, none of them worked

I have also sent your original files and csv to your gmail(mxkuhn@gmail.com), email subject: "Applied predictive modeling chap13 error" , all my classmates hit the same error, we could be flunked without your advice .

Steps to reproduce:

1. Run CreateGrantData.R to generate grantData.RData
2. Run 13_Non-Linear_Class.R and see if you can reproduce it on Line 367
3. all associated files have been sent to your gmail

BTW: Have you got my email ? from: joeyangx@yahoo.com, Thanks
