I am also getting the following warning with respect to package ichimoku(1.2.5) which was reported in #225.

Just wanted to bring to your attention in case it needs fixing.

  [UP] ignoring variable <unnamed var:   %4 = alloca %struct.SEXPREC*, align 8> as it has address taken, results will be incomplete
