plot(breakaway(frequencytablelist[[1]])) gives NULL

[Leran10]

Hi,

I'm trying to plot the breakaway() function but I got NULL:

> plot(breakaway(frequencytablelist[[1]]))
NULL

I tried the toy_otu_table and it worked well. I'm wondering if there is anything wrong with my breakaway(frequencytablelist[[1]]) result?

> breakaway(frequencytablelist[[1]])
Estimate of richness from method breakaway:
  Estimate is 44
 with standard error 0.21
  Confidence interval: (44, 44)
  Cutoff:  10

Thanks!
Leran

Thanks, Leran. Can you show us the output of

frequencytablelist[[1]]

? Then we can diagnose and fix if needed.

Thanks for your reply! Here is the result:

I am also having this issue.

breakaway version 4.8.4. Interestingly the example on the GetStarted vignette runs fine.

My example freq table is: (yes I know I may have too many singletons right now)!
