|An R Graph in JMP|
JMP 9 is now able to talk to the popular open source statistical software R.
JMP Scripting Language (JSL) is what allows JMP and R to work together.
Here are the most useful JSL functions for R:
//initialize the R session: RInit() //send a JMP object to R: int RSend(JMPObject) //get an object from R: object = RGet(RVariableName) //submit R code to R for processing: int RSubmit(RCode) //get the last graph made by R: picture = RGetGraphics(format) //terminate the session: int RTerm()
Here is a simple program:
- Open a sample table in JMP
- Send the data to R
- Make a scatterplot matrix in R
- Return the graph to JMP and display it
//open a JMP table: dt = Open("$SAMPLE_DATA/Big Class.JMP", invisible(true)); //initialize the R session (R must be installed on your computer): RInit(); //send the JMP data table to R: result = RSend(dt); //execute the R code. Make a scatterplot matrix: RCode = "plot(dt)"; result = RSubmit(RCode); //get the plotted graphic from R: graphic = RGetGraphics(png); //plot the graphic in JMP: NewWindow("Graph from R", PictureBox(graphic)); //terminate the session: result = RTerm();
Easy huh? The graphic at the top of this posting was done via the above code.
