Kurt, here's what S does (I recall going to some effort to duplicate the, at times, seemingly unusual behaviour of cat) S-PLUS : Copyright (c) 1988, 1996 MathSoft, Inc. S : Copyright AT&T. Version 3.4 Release 1 for Sun SPARC, SunOS 4.1.3_U1 : 1996 Working data will be in /users/rdev/rgentlem/.Data
x <- factor(c(1:3, NA), exclude=numeric(0)) x
[1] 1 2 3 NA
levels(x)
[1] "1" "2" "3" "NA"
cat(x, sep = "&")
1&2&3&4> cat(x, sep = "&\n") 1& 2& 3& 4
so, the behaviour of cat is the same (whether it's correct or not .....) robert =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
