class_equals_linter

Usage like <code>class(x) == "character"</code> is prone to error since class in R
is in general a vector. The correct version for S3 classes is <code><a href="/link/inherits()?package=lintr&version=3.0.2" data-mini-rdoc="lintr::inherits()">inherits()</a></code>:
<code>inherits(x, "character")</code>. Often, class <code>k</code> will have an <code>is.</code> equivalent,
for example <code><a href="/link/is.character()?package=lintr&version=3.0.2" data-mini-rdoc="lintr::is.character()">is.character()</a></code> or <code><a href="/link/is.data.frame()?package=lintr&version=3.0.2" data-mini-rdoc="lintr::is.data.frame()">is.data.frame()</a></code>.

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'.
