I’d like to solicit some advice on a debugging problem I have in the quantreg package. Kurt and Brian have reported to me that on Debian machines with gfortran 9
library(quantreg) f = summary(rq(foodexp ~ income, data = engel, tau = 1:4/5)) plot(f) fails because summary() produces bogus estimates of the coefficient bounds. This example has been around in my R package from the earliest days of R, and before that in various incarnations of S. The culprit is apparently rqbr.f which is even more ancient, but must have something that gfortran 9 doesn’t approve of. I note that in R-devel there have been some other issues with gfortran 9, but these seem unrelated to my problem. Not having access to a machine with an R/gfortran9 configuration, I can’t apply my rudimentary debugging methods. I’ve considered trying to build gfortran on my mac air and then building R from source, but before going down this road, I wondered whether others had other suggestions, or advice about my proposed route. As far as I can see there are not yet binaries for gfortran 9 for osx. Thanks, Roger Roger Koenker r.koen...@ucl.ac.uk<mailto:r.koen...@ucl.ac.uk> Department of Economics, UCL London WC1H 0AX.
