INTPLOT

This program produces interaction plots. The user inputs the information from the experimental design as a matrix. The information in this matrix will be stored in Matrix A and copied in Matrix B, in case of a mistake or if some other small modification needs to be made. The program will then ask for the number of levels in the ROW VARIABLE. For example if you have a 2 x 3 design where Factor A (the row factor) has 2 different categories, say old and new, then the number of levels is 2. The number of columns in the matrix will dictate the number of levels in Factor B (the column factor). After the matrix is entered in, the program will generate interaction plots. Great for experimental design classes or other classes where interactions are studied. Enjoy!
