Error in plot.window(...) : need finite 'ylim' values to generate graph in R-CodePudding

Could you help me plot the graph for the day 02/07, category ABC. The following error appears: Error in plot.window(...) : need finite 'ylim' values. If you try to generate for another day/category, thais is 30/06 (ABC category) and 01/07 (ABC category) it works, only for the day 02/07 that not. Could you help me? Thank you in advance!

CodePudding user response：

When there are only NA elements, and if we use range/min/max with na.rm = TRUE, it returns Inf

> min(NA, na.rm = TRUE)
[1] Inf
Warning message:
In min(NA, na.rm = TRUE) : no non-missing arguments to min; returning Inf
> max(NA, na.rm = TRUE)
[1] -Inf
Warning message:
In max(NA, na.rm = TRUE) : no non-missing arguments to max; returning -Inf
> range(NA, na.rm = TRUE)
[1]  Inf -Inf
Warning messages:
1: In min(x, na.rm = na.rm) :
  no non-missing arguments to min; returning Inf
2: In max(x, na.rm = na.rm) :
  no non-missing arguments to max; returning -Inf

One option is to return 0 if it is NA

...
 maxrange <-  range(min(0, datas$Numbers, na.rm = TRUE), na.rm = TRUE)
