RVariable

RVariable

Methods: change_arg_name, add_arg, remove_arg

This class represents OpenSHAPA variables (columns) in Ruby. Each variable has an array called cells that contains cells in RCell format. The basic way to access these cells is to loop over them, for example:

# First get the variable from the OpenSHAPA 
# database and load it into a Ruby object called var
var = getVariable("trial")  

# Now we loop over all of the cells
for cell in var.cells
    # puts is a simple command for printing whatever 
    # comes after it to the console
    puts var.ordinal  
end

will print out the ordinal of each cell. Not super exciting, but it shows how easy it is to loop over each cell.
