is_installed

When running automatic tests without building and installing the package,
i.e. with <code><a href="https://devtools.r-lib.org/reference/test.html">devtools::test()</a></code>, the package file structure is different
from the structure of a built and installed package (obtained with
<code><a href="https://devtools.r-lib.org/reference/check.html">devtools::check()</a></code>). For instance, the directory <code>inst/include</code> is
replaced by <code>include</code>, or <code>src</code> by <code>lib</code>. Check functions inside <code>rkeops</code>
have different behavior between these two cases.
The function <code>is_installed</code> checks the availability of the compiled
function <code>is_compiled()</code>. If available, it means that <code>rkeops</code> is
installed on the system.

The 'KeOps' library lets you compute generic reductions of very
large arrays whose entries are given by a mathematical formula with CPU and
GPU computing support. It combines a tiled reduction scheme with an
automatic differentiation engine. It is perfectly suited to the efficient
computation of Kernel dot products and the associated gradients, even when
the full kernel matrix does not fit into the GPU memory.

When running automatic tests without building and installing the package,

The function <code>is_installed</code> checks the availability of the compiled

Check if rkeops is installed on the system — is_installed

Check if <code>rkeops</code> is installed on the system
