Error in helperTestData(data) : Each treatment group must have at least two replicates

[elcega]

I have 17 samples, they are grouped like this (1,1,2,2,2,3,3,3,4,4,5,6,6,6,7,7,7). When running the following code

ret <- plotPCP(data_st, dataMetrics, threshVal = 0.1, lineSize = 0.3,
  lineColor = "magenta", saveFile = FALSE)

I get the following error:

Error in helperTestData(data) : 
  Each treatment group must have at least two replicates
    in the data object. For more information about formatting the data
object, see https://lrutter.github.io/bigPint/articles/data.html

So I tried grouping them in bigger groups (1,1,1,1,1,2,2,2,2,2,2,3,3,3,3,3,3) and still have the same error. So where does it detect or get the "replicate numbers"? Could I still do the analysis as 7 groups but one of the groups has no-replicates (no error bars)?

Hello @elcega

Thanks for writing about this issue. Yes, I can definitely look into this problem. Would you be able to paste the structure of your data_st and dataMetrics objects (i.e. the output of running str(data_st) and str(dataMetrics))? Then, I can try to replicate the problem and hopefully come up with a solution.

Before looking into it more thoroughly, I naively/hypothetically think I can update the code so that plotPCP() does not require replicates. It could cause some unexpected problems, but if not, hopefully I can make this change. I can try it out (and update you) while I try to solve the fuller issue.

Thanks again. Sincerely, Lindsay
