When handed an argument with all NAs, supsmu() causes a sigfault causing termination of R. The following example reproduces the problem (on a linux gentoo system), but I have verified the same behavior on a solaris builds as well as several versions of R.
x <- (1:100)/10; y <- sin(pi*x) + rnorm(length(x)); tmp <- supsmu(x,y); # works y[c(2,5,10)] <- NA; # a few NAs is OK, warning generated tmp<- supsmu(x,y); y<- NA + y; # all NAs tmp <- supsmu(x,y); # oops *** caught segfault *** address 0xfffffff8, cause 'memory not mapped' Traceback: 1: .Fortran(R_supsmu, as.integer(leno), as.double(xo), as.double(y[ord]), as.double(wt[o rd]), as.integer(iper), as.double(span), as.double(bass), smo = double(leno), double(n * 7 ), double(1)) 2: supsmu(x, y) Possible actions: 1: abort (with core dump) 2: normal R exit 3: exit R without saving workspace 4: exit R saving workspace Selection: --please do not edit the information below-- Version: platform = i686-pc-linux-gnu arch = i686 os = linux-gnu system = i686, linux-gnu status = major = 2 minor = 4.1 year = 2006 month = 12 day = 18 svn rev = 40228 language = R version.string = R version 2.4.1 (2006-12-18) Locale: LC_CTYPE=en_US.utf8;LC_NUMERIC=C;LC_TIME=en_US.utf8;LC_COLLATE=en_US.utf8;LC_MONETARY=en_US.ut f8;LC_MESSAGES=en_US.utf8;LC_PAPER=en_US.utf8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASURE MENT=en_US.utf8;LC_IDENTIFICATION=C Search Path: .GlobalEnv, package:stats, package:graphics, package:grDevices, package:utils, package:datase ts, package:methods, Autoloads, package:base ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
