# Set up data for example

		                     FORTYPCD = c(182, 184, 201, 221, 221, 184, 221, 182,
		                                  182, 201, 182, 221)))

# Frequency table with "FORTYPCD"       
datFreq(x = tab,
        xvar = "FORTYPCD")
		                                  
# Frequency table with "CONDCLASS" and "FORTYPCD" 		                                   
datFreq(x = tab,

# Frequency table with "CONDCLASS" and "FORTYPCD", adding total and subtotal
# rows

        xvar = c("CONDCLASS", "FORTYPCD"), 
        total = TRUE, 
        subtotal = TRUE)
        
# Frequency table for WYtree, multiple variables, subtotal options
