I created a txt file with R commands in it and then a batch file to process the txt file. The batch file could be scheduled. The batch file is:
REM on Microsoft Windows (adjust the path to R.exe as needed) 
"C:\Program Files\R\R-2.13.2\bin\x64\R.exe" CMD BATCH    "C:\Users\Frank\Documents\R\Scripts\Multi_Graph.txt" "C:\Users\Frank\Documents\R\Scripts\Multi_Graph.out"
The text file is:
x <- seq(-4, 4, length=100)
hx <- dnorm(x)
degf <- c(1, 3, 8, 30)
colors <- c("red", "blue", "darkgreen", "gold", "black")
labels <- c("df=1", "df=3", "df=8", "df=30", "normal")
plot(x, hx, type="l", lty=2, xlab="x value",
  ylab="Density", main="Comparison of t Distributions")
for (i in 1:4){
  lines(x, dt(x,degf[i]), lwd=2, col=colors[i])
legend("topright", inset=.05, title="Distributions",
  labels, lwd=2, lty=c(1, 1, 1, 1, 2), col=colors)

This produces a nice plot.
