Repeated-measures ANOVA error with high(ish) number of cells

Hi all,

JASP is great, thanks for developing it! An issue that has persistent over the past and current versions occurs when the number of cells in a repeated-measures ANOVA is relatively high.

When running a 3x9 rm-ANOVA, I get the following in JASP 0.8.2:

Error message, including stack trace:

This analysis terminated unexpectedly.

Error in complete.cases(x, y): not all arguments have the same length

Stack trace
analysis(dataset = NULL, options = options, perform = perform, callback = the.callback, state = state)

.resultsPostHoc(referenceGrid, options, dataset, fullModel)

t.test(unlist(postHocData[listVarNamesToLevel[[k]]]), unlist(postHocData[listVarNamesToLevel[[i]]]), paired = T, var.equal = F)

t.test.default(unlist(postHocData[listVarNamesToLevel[[k]]]), unlist(postHocData[listVarNamesToLevel[[i]]]), paired = T, var.equal = F)

complete.cases(x, y)

To receive assistance with this problem, please report the message above at: https://jasp-stats.org/bug-reports

The message in 0.7.1.12 used to be Invalid comparison with complex values, and has been reported on GitHub before (raised in September 2015; closed in March 2017 in anticipation of whether it was still a bug in the latest version).

Please note that the issue does not seem to be with the data: Running 2x9 rm-ANOVAs on the same data does work, and I've had the same issue with a completely different dataset. The only common factor seems to be the number of cells.

UPDATE (2017-09-14, 12:34 UTC+0): The same data does work with 2x9 rm-ANOVAs on JASP 0.7.1.12, but not on 0.8.2. On 0.8.2 it does work in a 3x6 design.

Any idea what might be going on?

Cheers,

Edwin

    No idea! Can you attend us to this problem again please (on GitHub)? It would be good to sort this out
