Undefined control sequence in manual pages

[jeroen]

When I run R CMD build on drake, it errors as follows (both on linux and mac):

LaTeX errors when creating PDF version.
This typically indicates Rd problems.
LaTeX errors found:
! Undefined control sequence.
<argument> Rfn.\lifecycle
                          .Rlbrace.maturing.Rrbrace.
l.7394 ...s}{\lifecycle.Rlbrace.maturing.Rrbrace.}

It seems to pass on travis. Any idea what I am doing wrong?

I just started getting is error too, and here it is on Travis. I am not sure why, but I expect they are related to my use of lifecycle badges.

My apologies: there is one place where I put \lifecycle{} under @aliases instead of @title. Patch forthcoming.
