title: Error: package or namespace load failed for ‘ChemmineOB’
body: <p>I installled ChemmineR and ChemmineOB on my MacOSX (MacOS Big Sur; R version 4.1.2) like this:</p>
  <pre><code>if (!require(&quot;BiocManager&quot;, quietly = TRUE))
  install.packages(&quot;BiocManager&quot;, dependencies = TRUE)
  BiocManager::install()
  library(&quot;BiocManager&quot;) #Loads the package
  BiocManager::install(c(&quot;ChemmineR&quot;,&quot;ChemmineOB&quot;))
  BiocManager::install()
  library(&quot;ChemmineR&quot;) #Loads the package
  library(&quot;ChemmineOB&quot;) #Loads the package
  </code></pre>
  <p>However, when loading ChemmineOB I repeatedly get this error:</p>
  <pre><code>Error: package or namespace load failed for ‘ChemmineOB’:
  .onLoad failed in loadNamespace() for 'ChemmineOB', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)

  <p>Is there something I'm missing? I would be grateful for any help.</p>
