R中的filled.contour（）：标记轴 - cex，las，et al

Question

I want to use filled.contour() to plot some data I have in a matrix.

Everything is perfect until when I import the graphics into my tex file and realize I need to play with the font size for it to be readable in the final document.

Unfortunately, it seems I am unable to tune the parameter cex in filled.contour(), and the same goes for las (I'd like the ylabel to be parallel to the x axis).

Below is a simple example. Although I expected the output to be different in each case, namely the font size, the produced plot is pretty much the same.

Thanks a lot for any help you can give me on this.

    x=1:10
    y=1:10
    z=array(rnorm(100),dim=c(10,10))
    filled.contour(x,y,z)
    filled.contour(x,y,z,xlab='x',ylab='y')
    filled.contour(x,y,z,xlab='x',ylab='y',las=1)
    filled.contour(x,y,z,xlab='x',ylab='y',las=1,cex=2)
    filled.contour(x,y,z,xlab='x',ylab='y',las=1,cex=20)

@QuantIbex is right, though you can also pass through other graphics parameters by specifying in the plot.title , plot.axes , key.title and key.axes arguments.

This is necessary because the usual graphics parameters are not passed straight through, as described in ?filled.contour :

 ...: additional graphical parameters, currently only passed to
      ‘title()’.

Eg:

x=1:10
y=1:10
z=array(rnorm(100),dim=c(10,10))

filled.contour(x,y,z,las=0,
  plot.axes={
              axis(1,cex.axis=2)
              axis(2,cex.axis=2)
            },
  plot.title={
              title(xlab="x",cex.lab=2)
              mtext("y",2,cex=2,line=3,las=1)
  }
)
