title: Bar plot from dataframe by row values using ggplot
body: <p>I have a following dataframe:</p>
  
  <pre><code>      Alue  SDP   PS  KOK KESK VIHR  VAS RKP  KD SIN PIR STL KP  FP LIB SKP EOP  IP SKE KTP Muut Vaalipiiri
  1 Helsinki 13.5 12.3 21.8  2.9 23.5 11.1 5.3 1.9 0.5 1.5 0.3  0 0.9 0.3 0.2 0.2 0.1 0.1   0  3.5   Helsinki
  </code></pre>
  
  <p>I would like to draw a bar plot showing the 1st row value of each column on its own bar. The problem seems to be that i can't draw bar plot by row, only by column. I have tried to draw a plot like this:</p>
  
  <pre><code>ggplot(testi2, aes(testi2[0,], testi2[1,))+
    geom_col()
  </code></pre>
  
  <p>but it doesn't work :(</p>
