BN Learn Error

[rpazo001]

Here is the error I keep getting. The data = RATBN and the network is BN13a. Compile comes from the "gRain" package.


library("tidyverse")
library("bnlearn")
library("gRain")

#### Class BN
> class(Bn13a)
[1] "bn"

> class(RATBN)
[1] "data.frame"

> bn.bayes<-bn.fit(Bn13a,data=RATBN,method="bayes",iss=1)
>
> ### Compile data
> junction <-compile(as.grain(bn.bayes))
