R custom component using 'recommenderlab' library returns a general error, works in R - why?
I am trying to run 'recommenderlab' library of R with SAP PA custom component.
I have tested it in many ways - it is a new library, so I thought that maybe it is not keen on those, that haven't been included in the default installation. I found a place, where SAP PA configures stuff what to include in the installation of R and reinstalled but to no avail.
Then I tried another library - seriation - that that had not been included, but this worked, even without being included in SAP PA installation script (I had seriation previously in my local R installation, though). Whereas the recommenderlab library, once I give the first command: q<-as(mydata, "realRatingMatrix”): which coerces the original SAP data to a realRatingMatrix form with the help of the package, just gives an error.
The SAP PA error message, once I add the row is a general one:
Error, could not find function MyMain.
In the SAP PA logs, I get a more detailed error message:
Error during processing response.: boolean is not a function
The script works fine in my R installation and thus I don't know what to do next?
mymain <-function(mydata, howmany)
r<- Recommender(q, method = "POPULAR")
recom <- predict(r, q, n = howmany)
res<-cbind(rep(seq_along(l), times=sapply(l, length)), unlist(l))
output <- as.data.frame(res)
