I'm trying to create a custom OrgDb for tomato.

First I tried to add Uniprot table to the OrgDb with 

https://github.com/kozo2/org.Sl.eg.db/blob/master/tomatoMakeOrgPkg.R

but I had an error like

May I ask for any advice?

I checked this error on R 3.2.2 + Annotation Forge 1.12.0 on Windows 10 and Mac OS X El Capitan‎.

You can reproduce this error with the following commands.

git clone git://github.com/kozo2/org.Sl.eg.db
cd org.Sl.eg.db

> install.packages("splitstackshape")
> source("https://bioconductor.org/biocLite.R")
> biocLite("AnnotationForge")
> source("tomatoMakeOrgPkg.R")

> fUniprot <- as.data.frame(fUniprot)
> library(AnnotationForge)
> #makeOrgPackage(gene_info = fSym, chromosome = fChr, go = fGO,
> # this does NOT work
> makeOrgPackage(gene_info = fSym, chromosome = fChr, go = fGO, uniprot = fUniprot,
