[R] Words appear to be bolded in the PDF output

Hi all, I have written a note near each of my graphs using mtext. mtext(text,side=1,line=4,cex=0.5,adj=0) Then I have exported the graphs as a PDF file. pdf(file=name,paper='a4',width=7.27,height=10.69) The mtext appears OK in R. But it looks like it is bolded in the PDF file. http://n4.nabble.

[R] Polynomial equation

Hi all, I have got a dataset. In Excel, I can fit a polynomial trend line beautifully. However, the equation that Excel calculates appear to be incorrect. So I am thinking about using R. My questions are: (1) How do I fit a polynomial trendline to a graph? (2) How do I calculate and display the
