different subscripting behaviour using $<- or [<- for data.frames (PR#387)
I observe if> char <- letters[1:2] > fac <- factor(char) > dd <- data.frame(char=I(char), fac=fac)then> dd[,"char"] <- char > dd[,"char"][1] a b Levels: a b and> dd$char <- char > dd$char[1] "a" "b" are different. After the latter operation the data.frame contains a character column, which neither has attribute "AsIs" nor has been converted to class factor. Is this intended? platform Windows arch x86 os Win32 system x86, Win32 status major 0 minor 90.1 year 1999 month December day 15 language R -- Dr. Jens Oehlschlägel-Akiyoshi MD FACTORY GmbH Bayerstrasse 21 80335 München Tel.: 089 545 28-27 Fax.: 089 545 28-10 http://www.mdfactory.de Standard Disclaimers: Opinions expressed here are personal and are not otherwise represented. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- 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 !)
