you can find it by use of indexing with setting 1=T and 0=False in your

It probably doesn't make much difference in this small example, but
maybe it's worth noting that **if possible** (it typically is not),
things can be speeded up by generating all the random numbers at once
then applying a vectorized operation to the entire ensemble. In this
case, this becomes:

Data is not information. Information is not knowledge.
My intention is to include certain columns if they meet certain criteria.
For example, if b is one of the columns of a1, then keep otherwise don't.

Don's response seems apropos to me. Do you understanding indexing,
i.e. the [ operator? If not, you should read An Introduction to R or
other tutorial (there are many good ones on the web). If that is not
the issue, you need to explain more clearly why his answer does not
suffice.
Cheers,
Bert
I don't think apropos or indexing would help. I am open to your
suggestions/tips.
I usually get multiple versions of a dataset (even with the same column
names). In the source data, I occasionally notice inconsistencies...
formatting issues, column naming issues etc..
As shown In the a1
At the risk of being annoying ...
Your original question was,
Is there a way to dynamically include columns in a dataframe?
The answer is yes. One way, and I think the simplest, is to calculate the
names of the columns you want to keep, and then use an expression like I
suggested, that is, one
I agree with Don... focus on identifying the names of the columns and then use
column name indexing to extract the columns you want. You will probably want to
rename them to a standard set of names once you have gone to all this
trouble... just assign the new vector of names to the names

This probably doesn't answer your question, but, amazingly enough, try
googling the class name.
It worked for GAlignmnets.
Incidentally, there's no reason class names have to be unique among R
packages.. And they can be hidden in namespaces.
