title: How make labels for bar names a smaller font size in barplot()?
body: <p>Using the barplot() function here below:</p>
  <pre><code>barplot(
  norm_clade_counts[[tax_level]][ok,all],
  col = mycols(length(ok)),
  las = 2,
  names.arg = paste(sample_type[all], sample_name[all])
  )
  
  legend(
  &quot;bottomleft&quot;, bty = &quot;n&quot;, pch = 19,
  col = mycols(length(ok))[1:length(ok)],
  cex = 1, inset = c(1,0), 
  legend = rownames(clade_counts[[tax_level]])[ok]
  )
  </code></pre>
  <p>And the barplot I get looks like this, where the names of the bars are not fully visible in the window. How do I change the fontsize of these labels? <a href="https://i.stack.imgur.com/fuC7R.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fuC7R.png" alt="enter image description here" /></a></p>
