your VAL is still data frame. See ?"[" and link to data.frame method. Use str(object) to see the structure of your object not just printing it to console as print is a function which has also different methods for different objects and does not inform you about nature of your object. You shall profit from reading R-intro which I believe you have overlooked. It shall be installed in doc/manual directory of your R installation.
