Good day,
A self-contained example which reproduces the problem is
packagesFolder <- tempdir()
latestFolder <- file.path(packagesFolder, "latest")
dir.create(latestFolder)
devtools::create(file.path(latestFolder, "statistics"), description =
list(Version = "1.1.0", Depends = "extras (>= 1.0.5)"

I don't think it has much to do with transform in particular:

The idea is that one wants to write the line of code below
in a general way which works the same
whether you specify ix as one column or multiple columns but the naming entirely
changes when you do this and BOD[, 1] and transform(BOD, X=..., Y=...) or
other hard coding solutions still require writ

I think you meant to call BOD[,1]
From ?transform, the ... arguments are supposed to be vectors, and BOD[1] is
still a data.frame (with one column). So I don't think it's surprising
transform gets confused by which name to use (X, or Time?), and kind of
compromises on the name "Time". It's also
