Thanks so much for the tips, I was able to use both parse() and eval()... I
found eval(), quote(), bquote() easier and more flexible to use and to pass
as arguments to a function.
I can't say enough that you really made my day! :)
Thanks,

Dear R gurus..
I had tried out some suggestions sent to me privately..and unfortunately,
they did not work..
To use a condiition in a subset, the associated dataframe needs to be
attached and detached, which I found cumbersome to use if using more than 1
dataframe (with different dimensions) with

Hi,
an alternative to parse() is to use quote and bquote,
set.seed(123)
d = data.frame(a=letters[1:5], b=1:10, c=sample(0:1, 10, repl=TRUE))
cond1 - quote(a==b)
cond2 - quote(b 6)
cond3 - bquote(.(cond1) .(cond2))
subset(d, eval(cond1))
subset(d, eval(cond2))
subset(d, eval(cond3))
