The two methods implementing set and get variable to/from R are SetSym(<VarName>,<VarValue>)
and GetSym(<VarName>).
The first one returns nothing, second one returns the variable value. The second
method could be replaced by Eval(<VarName>).
For the purpose of these example Rp tool board must be loaded.
Example 1
Objective: Set variable "a" to 6, and get the same variable in result field.

Example 2
Objective: Set variable "z" to the matrix from dt1 data board, and get the same variable into another data board.

Example 3
Objective: Set Sicyon variables "a" and "d" to R, and get the variable "d" to result field.

Example 4
Objective: Copy Sicyon variables "a" and the matrix "dt8" from Sicyon to R and then get the last one in result field.
Similar to the example 3 above but using matrices: dt8 is control data board for Sicyon and CopySVars makes a copy of it in R.
