Error when running AnomalyDetection with Rscript

[joaoborges]

Hello,

when running AnomalyDetection inside R (gui or interactive terminal) I have no errors, but when running with Rscript I've got the following error:

Error in .setupMethodsTables(fdef, initialize = TRUE) :
  trying to get slot "group" from an object of a basic class ("NULL") with no slots
Calls: AnomalyDetectionTs ... getMethodsForDispatch -> .getMethodsTable -> .setupMethodsTables
Execution halted

Thus, to fix this I had to include library(methods) in my script.

Although it is running ok with this, it is generating a Rplots.pdf file after each iteration, which may indicate the cause for the above error.

I'm having the same issue using Rscripts. Everything works fine with library(methods) in the script, or alternatively using R CMD BATCH.

These appear to be related:

It's because the graphics device is being opened even when "plot=FALSE" is set. Reference the "plot.new()" call at the end of ts_anom_detection.R and vec_anom_detection.R. This appears to be fixed in tag v1.0.1, but it's not in the master.

Try reinstalling with the tag explicitly specified:
devtools::install_github("twitter/AnomalyDetection", ref="v1.0.1")
