createVector function

Create a GUI with a Vector Widget

Create a basic window containing a vector and a submit button. This provides a quick way to create a window without the need for a window description file.

createVector(vec, vectorLabels=NULL, func="", 
    windowname="vectorwindow", env=NULL)

Arguments

• vec: a vector of strings representing widget variables. The values in vec become the default values for the widget. If vec is named, the names are used as the variable names.
• vectorLabels: an optional vector of strings to use as labels above each widget.
• func: string name of function to call when new data are entered in widget boxes or when "GO" is pressed.
• windowname: unique window name, required if multiple vector windows are created.
• env: an environment in which to evaluate widget callback functions.

## Not run:

local(envir=.PBSmodEnv,expr={
#user defined function which is called on new data  
drawLiss <- function() {
  oldpar = par(no.readonly=TRUE); on.exit(par(oldpar))
  getWinVal(scope="L");
  tt <- 2*pi*(0:k)/k; x <- sin(2*pi*m*tt); y <- sin(2*pi*(n*tt+phi));
  plot(x,y,type="p"); invisible(NULL); };

#create the vector window
createVector(c(m=2, n=3, phi=0, k=1000), func="drawLiss",
  vectorLabels=c("x cycles","y cycles", "y phase", "points"));
})
