Someone who was running into an integer overflow warning (and downstream error) with mantelhaen.test() on a large data set asked about it on StackOverflow:
https://stackoverflow.com/questions/48422398/na-nan-inf-in-foreign-function-error-with-mantelhaen-test/48428596#48428596 Coercing ntot to double (i.e. ntot -> as.numeric(ntot)) on lines 283 and 285 here: https://github.com/wch/r-source/blob/af7f52f70101960861e5d995d3a4bec010bc89e6/src/library/stats/R/mantelhaen.test.R#L283 seems to fix the problem, fairly harmlessly (*maybe* there are some edge cases where the integer and floating-point computations give different answers??? these values are going to get sent to qr.solve() a few lines later in any case ...) If people think this is worthwhile I could submit a bug report. cheers Ben Bolker ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
