Newbie question: R tool runs in workflow but does not work as a Macro

[PAFlores]

Newbie question/issue.

I have a "bit" of R that I use to prep data to generate some box and whisker charts that runs in the R Tool but when I try to turn it into a macro that I can reuse it returns a rather ambiguous error (Error: Quartile (4): R-QuartileBody: Error in `[.data.frame`(myList[[i]], c("Measurement")) : ).  Attached is a data file that can be used to test the script and what I am seeing.

Below is the body of the R.

Can anyone tell me what I am missing?  Or where I have gone wrong? 

Thanks in advance for the assistance!

mlinValue<-as.data.frame(minValue)

StdDevValue<-as.data.frame(StdDevValue)
Q1=quartile[1]
Q2=quartile[2]
Q3=quartile[3]
Q4=quartile[4]

CalcValues<-data.frame()
CalcValues<-data.frame(Q1,Q2,Q3,Q4,Q5,medianValue,minValue, maxValue,StdDevValue)
DataList[[i]]<-CalcValues
}
ResultSet=do.call(rbind, DataList)

write.Alteryx(ResultSet, 1)

Figured it out!  Configuration of the Macro Input to process a test input data source cleaned up the issue!
