	Dear Sir/Madam,

Sorry for my previous message. I am to call R from java. I did a search here and
I found some recommendations telling me to use jri which comes with rJava. I
have managed to install the package successfully on my machine. I also managed
to run the default example rtest successfully. I tried to find more tutorials or
or examples,but I could not find any. I am trying to do the following from the
java class:


  png('/home/saleh/figure13.png',height=480*5,width=480*5,res=72*5)  

  y1 <- cumsum(rnorm(100))

  y2 <- cumsum(rnorm(100, mean=0.2))

  par(mai=c(.8, .8, .2, .8))

  plot(1:100, y1, type="l", col="blue", xlab="X axis
label", ylab="Left legend")

  par(new=TRUE)

  plot(1:100, y2, type="l", ann=FALSE, yaxt="n")

  axis(4)

  legend(x="topleft", bty="n", lty=c(1,1),
col=c("blue","black"),

        legend=c("String 1 (left scale)", "String 2 (right
scale)"))

  dev.off()  


These commands can be run correctly from the R command, but I am trying to do
that from a java class.


Any help would be really appreciated.


Regards,

Saleh.
