incorrect number of subscripts

[blackcoral]

I have been trying to use the iNEXT function from the following code. This worked in version 2.0.13 in R x64 3.3.2. For some reason I get the follow error and I am not sure what the problem is. The best I can tell is that this error started when I updated my install versions.

points <- 400
acc_curve <- iNEXT(species_data_matrix,q=0, datatype = "incidence_raw", endpoint = points, nboot = 1000, knots = points, conf = 0.95)

Error in arr[1, , ] <- t(as.matrix(ChaoSpecies(x, datatype, conf))) :
incorrect number of subscripts

The data matrix is listed as species in the row name and site name in the column name with 0 or 1 for presence/ absence. I can try to upload the data if needed.

Thanks for any help.

Have you find a solution to this problem? I'm getting the same error. Similar to your problem, this is a script that used to work.
Same error:

Error in arr[1, , ] <- t(as.matrix(ChaoSpecies(x, datatype, conf))) : 
  incorrect number of subscripts

I did solve the problem but didn’t post it. Put your matrix in a list and it should work. It appears that you can not directly use a matrix anymore but has to be a list of matrixes. I think it should be ok to just have one but this actually helped me more as I had several curves I was making so I am able to do run them together instead of individually. Good luck.

Thank you! This was very helpful, converting the matrix to a list works. Also, there is an error when plotting the iNEXT object. I solved based on the response here.

names(iNEXT_object$iNextEst) <- "random"
