adjust font in ggplot2 to LaTeX document
Hi, how can i adjust the font in a ggplot2 qplot so that it will look similar to the LaTeX font? Computer Modern Sans Serif in the same size would be nice.

par.plot() for repeated measurements
Hello, I am using the package gamlss in R to plot repeated measurements. The command I am using is par.plot(). It works great except one thing about the label of the axises. I tried to label both x and y axises using ylab and xlab options. But the plot only gives variable variables. The labels did not show up. Below is the code I used. Any comments are appreciated!
