title: Scatterplot: color and italicize axis labels
body: <p>in a R scatterplot I want to give the Y-Axis labels colours and make part bold, other parts italic. I start from a very simple plotting script, where everything is done, except the making the font bold, italic and giving it a colour:</p>
  
  <pre><code>png("test.png", height=800, width=600, pointsize=15)
  par(mar=c(5,12,.25,1))
  textA=seq(0,100,25)
  textB=c("start","intermediate1","intermediate2","intermediate3","stop")
  plot(c(0,runif(8),1),c(0,runif(8),1),axes=F,ylab=NA)
  axis(1)
  axis(2, at=seq(0,1,.25), labels=paste(textA,"-",textB,sep=""),las=2,cex.axis=1.5)
  dev.off()
  </code></pre>
  
  <p>Question: How can I make the textA bold and coloured (red) and at the same time make the textB just italic, not bold, standard colour (black).</p>
  
  <p>Thanks so much.</p>
