PTA with target=makePTAtarget()

[PKPDICU]

Hello everyone,
I am trying to calculate PTA/CFR for AUC/MIC > 80 for a range of MIC and their related distribution.
I have extracted epidemiological data from EUCAST website to do this, with makePTAtarget() command
The script ran well when it was simply a target list, but now it crashes with the error message :

Error in auc/randTarg : non-numeric argument to binary operator

Here is the script I used :

make<-data.frame(c(0.002,0.004,0.008,0.016,
                             0.03,0.06,0.125,0.25,0.5,
                          1,2,4,8,16,32,64,128,256,512),
                    c(0,0,0,0,0,15,217,1034,6359,44948,
                         68510,7728,68,39,23,4,6,0,1154))
makePTAtarget(make)

target     n

simiv<-c("a30mS12","c30mS8","e30mS6","g12hSci","i8hSci","k6hSci")
pta1_3 <- PM_pta$new(simdata = c("simout1.txt","simout3.txt","simout5.txt",
                                 "simout7.txt","simout9.txt","simout11.txt"), 
                     simlabels=simiv, target = makePTAtarget(make),target.type = "auc",
                     success = 80,
                     start = 0, end=24,
                     free.fraction=0.7)

Would anyone have the solution or an explanation? Thank you in advance
