[R] Calculate AUC Using the Trapezoidal Method

[Chris Campbell]

The arguments time, id and dv take character strings.

AUC(Data, time = "Time", id = "Fraction", dv = "Variable")  
  Fraction      AUC
1       C1 4413.549

Subject: [R] Calculate AUC Using the Trapezoidal Method

Hello,
I want to use function AUC {MIfuns} but I have problem with arguments.
My data:
 Fraction Time Variable
C1     0  0.00000
C1   15  20.95475
C1    30 28.55030
C1    60 36.33064
C1    90 48.80438
C1  120 60.18636
 
AUC(data, time = Time, id = Fraction, dv = Variable)  ##this is not working!



Thx!
