The strptime object is a structured list object with 9 components. (Type "names(z)" to see the names of the individual components). You may want to convert the strptime object to a POSIXct object using
Z = as.POSIXct(z) This is just a vector (of the expected length).

Of course this implies that any replacement I want to do with dates etc. always fails with the error: Error in "[[<-.data.frame"(*tmp*, D[I], value = strptime(as.character(x[[D[I]]]), : replacement has 9 rows, data has 5970 > > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 1 minor 7.0 year 2003 month 04 day 16 language R > (platform Win2000 professional) Has anyone else encountered this?
