I was just writing the same observation: it is when I run view().

gabx using magnolia [R] short_j <- journal(
...   timestamp = short$value,
...   amount = short$executed_qty,
...   price = short$price,
...   instrument = short$symbol
... )
gabx using magnolia [R] View(short_j)
Error in names[[i]] : subscript out of bounds

As you can see, I can build the short_j journal with no error, but it
is when I want to view it.
I use Rstudio on Archlinux.
When running 
R > utils::View(btc_journal)

a pop up window open with the journal in a correct view.

So there is something wrong with Rstudio ? Or any package of my linux
distro?
