inner_combine_linter

<code>as.Date(c(a, b))</code> is logically equivalent to <code>c(as.Date(a), as.Date(b))</code>;
ditto for the equivalence of several other vectorized functions like
<code><a href="/link/as.POSIXct()?package=lintr&version=3.0.2" data-mini-rdoc="lintr::as.POSIXct()">as.POSIXct()</a></code> and math functions like <code><a href="/link/sin()?package=lintr&version=3.0.2" data-mini-rdoc="lintr::sin()">sin()</a></code>. The former is to be
preferred so that the most expensive part of the operation (<code><a href="/link/as.Date()?package=lintr&version=3.0.2" data-mini-rdoc="lintr::as.Date()">as.Date()</a></code>)
is applied only once.

Checks adherence to a given style, syntax errors and possible
semantic issues.  Supports on the fly checking of R code edited with
'RStudio IDE', 'Emacs', 'Vim', 'Sublime Text', 'Atom' and 'Visual
Studio Code'.
