[R] assignment of inidividual variables from spss save files

[BXC (Bendix Carstensen)]

The key to solving your problem is that read.spss per default
gives you a *list* and not a *dataframe* (can anyone explain this
choice of default?).

So most likely wou want:

children = read.spss(filename,to.data.frame=TRUE)
attach(children)

or to get things a little more handy:

children <- read.spss(filename,to.data.frame=TRUE)
names(children) <- tolower( names( children ) )
attach(children)

best,
