Error in sprintf("%s not found! Interpreting dose as nanomolar concentrations.") issue

[platanus]

I have the problem associated with sprint error in R 3.6.3(using Rstudio terminal tab).
Let me know how to solve below error.

-Command used in Rstudio terminal tab-

   Rscript AP_simulation.R -d drug1 -x "1-10,15,20,25" --cmaxfile="my_cmax_table.csv" --hergpath="path/to/herg/results/" --hillpath="path/to/hill/results/"-

-Error result example-

   loaded via a namespace (and not attached):
   [1] compiler_3.6.3 getopt_1.20.3
   Error in sprintf("%s not found! Interpreting dose as nanomolar concentrations.") :

   Calls: print -> sprintf

-Rcode part(AP_simulation.R) that may occur error-

  #--- get therapeutic concentration (Cmax)
      if(drug=="control"){
        cmax<-0
      }else{
      if(!file.exists(cmaxfile)){
        cmax<-1
       print(sprintf("%s not found! Interpreting dose as nanomolar concentrations."))
      }else{
      drugtable<-read.csv(cmaxfile)
      cmax<-drugtable[as.character(drugtable$drug)==drug,"therapeutic"] # should be in nanomolar
      if(length(cmax)==0){
       cmax<-1
       print(sprintf("Cmax undefined, interpreting dose as nanomolar concentrations."))
      }else if(length(cmax)==1){
       print(sprintf("Cmax set to %g nM, interpreting dose as multiples of Cmax.",cmax))
      }else{
        stop("Multiple entries for %s therapeutic concentration!",drug)
      }
    }
   }

The command that you entered is for your own data and needs "my_cmax_table.csv" in the current working directory but I believe that you don't have it.

If you're just testing the scripts and do not possess your experiment data, you do not need to run this command. (Optional)
