R help - Oct 2011 - Drop ALL Levels of a Data Frame Object

I'm using the package 'gdata' and 'drop.levels' in the
following code as a
simplified example of what I want to do, pinpointing the issue of isolating
variable in a data frame:

/dfNamesAndHeight <- data.frame("Name" =
c('Bill','Bob','Bo'), "Height" c(73,68,83))
name_Bob <- drop.levels(dfNamesAndHeight[2,1])
cat(name_Bob, " is a good guy.") 
/

The output is "> 1  is a good guy". Print instead of cat returns
">Error in
print.default(xx, quote = quote, ...) : invalid 'quote' argument".
When you
just enter 'name_Bob' the output is:

 " >[1] Bob
Levels: Bob"

Is there any way to isolate 'Bob' without the 'Levels: Bob'?

Why aren't you using as.character instead of drop.levels?

No worries for the brevity. That worked exactly like I wanted. Thank you.
