invalid class errors of regressionBF with R3.3.3

[Smalboy]

Hi,

when trying "BF_score <- regressionBF(yval ~ xval,data=res_scores)", it works OK with R3.4.*, but the following error message was present when I ran the command line in the R3.3.3:

invalid class “BFBayesFactor” object: Some numerators are not BFmodel objects. Calls: logBF_scores[note: MY FUNCTION] ... BFBayesFactor -> new -> initialize -> initialize -> validObject

Best, Chunliang

Can you provide a reproducible example?

[Smalboy]

Yes. The following code was in a "BF_test.R" file, and I ran it in the terminal with: Rscript ./BF_test.R > BFtest.txt. The following error message is present.

This works fine for me in R 3.3.3:

library(coda)
library(BayesFactor)

set.seed(1)
res_scores <- data.frame("xval"=runif(60),"yval"=runif(60))
BF_score <- regressionBF(yval ~ xval,data=res_scores,progress=FALSE)
print(BF_score@bayesFactor$bf)
# [1] -1.335096

It could be related to how you've installed your library; have you tried re-installing the package under R 3.3.3?

Thanks Richard. I got it running in the R console ~Best, Chunliang.
