Error while plotting series chart.

[13367356107]

This error occurred when I was drawing with sample data. The "series graph " made has no color and no legend of threshold.

library(mem)
data("flucyl")
full.series.graph("flucyl")
Error in sum(x, na.rm = T) : invalid 'type' (character) of argument
In addition: Warning messages:
1: In min(as.numeric(rownames(i.data)[1:3])) :
no non-missing arguments to min; returning Inf
2: In min(as.numeric(rownames(i.data)[1:(min(3, NROW(i.data)))])) :
no non-missing arguments to min; returning Inf
3: In max(as.numeric(rownames(i.data)[(max(1, NROW(i.data) - 2)):NROW(i.data)])) :
no non-missing arguments to max; returning -Inf

sorry! I found it should be "full.series.graph(flucyl)". ....SO! Why the threshold information is not presented on the graph？

full.series.graph(
  i.data,
  i.range.x = NA,
  i.range.y = NA,
  i.output = ".",
  i.graph.title = "",
  i.graph.subtitle = "",
  i.graph.file = T,
  i.graph.file.name = "",
  i.plot.timing = F,
  i.plot.intensity = F,
  i.alternative.thresholds = NA,
  i.color.pattern = c("#C0C0C0", "#606060", "#000000", "#808080", "#000000", "#001933",
    "#00C000", "#800080", "#FFB401", "#8c6bb1", "#88419d", "#810f7c", "#4d004b"),
  i.mem.info = T,
  ...
)

Set those two parameters to true:

  i.plot.timing = F,
  i.plot.intensity = F,

Concerning the first issue: "flucyl" is a char object that contains the string "flucyl", flucyl is a dataset that contains rates to draw the graph

oh！it worked，thank you！

When I use the example sentences of "roc.analysis", I find that if I set different parameter ranges (1-5 or 2-4), I get different sensitivity, specificity, etc. This phenomenon also occurs on "memapp" when I adjust the parameters from 1-5 to 2-4.
It seems to be related to "i.detection.values".
For the "mem" program, if I want to use the "fixed criterium method" to optimize the model and set the parameters to range from 2-4, which parameter do I need to set ("i.detection.value" or "i.param") , or they need to set the same range?

When I set "i.detection.values" it iterates from 1 to 5 regardless of the parameter range. Using the same criteria to select optimal parameters, Youden's index, results will vary due to differences in specificity and sensitivity. Setting a different "i.param.values" parameter range does not affect the result. The results for specificity and sensitivity were consistent. When setting different "i.param.values" parameter ranges does not affect the result. The results of specificity and sensitivity were consistent.
My problem may be not understanding the difference and connection between "i.param.values" and "i.detection.values".
