title: boxplots with missing values in R - ggplot
body: <p>I am trying to make boxplots for a matrix (athTp) with 6 variables (columns) but with many missing values, '</p>
  
  <pre><code>ggplot(athTp)+geom_boxplot()
  </code></pre>
  
  <p>But maybe sth I am doing wrong...</p>
  
  <p>I tried also to make many box plots and after to arrange the grid, but the final plot was very small (in desired dimensions), loosing many of details.</p>
  
  <pre><code>q1 &lt;- ggplot(athTp,aes(x="V1", y=athTp[,1]))+ geom_boxplot()
  </code></pre>
  
  <p>..continue with other 5 columns</p>
  
  <pre><code>grid.arrange(q1,q2,q3,q4,q5,q6, ncol=6)
  
  ggsave("plot.pdf",plot = qq, width = 8, height = 8, units = "cm")
  </code></pre>
  
  <p>Do you have any ideas?
  Thanks in advance!</p>
