From your question it is not clear what your question/concerns really are,
and from what we can see it could very well be that you do not understand
the statistics that you are computing (not just the R implementation). We
ask for a reproducible example because that helps us to

I will likely go with a list of data frames as each data frame will
represent independent entities and as the syntax will probably be

I did find it puzzling that multidimensional data frame or the ability

Hi,
I'm trying to combine 15 different data frames but all have time field as
common. But the thing is time intervals are different (like min's and
sec's).
So I have to check the common time from all the 15 data frames and merge it
to a single data frame and then export it to excel or csv.
You might want to use the profiler (Rprof) on a subset of your code to
see where time is being spent. Find a subet that runs for a minute,
or so, and enable profiling for the test. Take a look and see which
functions are taking the time. This will be a start. You can also
watch the task monitor
You at least need to provide a subset of what the data looks likes.
Since you are merging on 'time', if there are not the same times in
each set, then you will have missing values. For example, in the
merges that you are doing, have you looked at the size of the
resulting object compared to the

Hi Bert,
Thank you for the code.
However, I don't see what I am doing different, but my output is different.
I would much rather have output similar to yours where only the input
objects are returned (instead of the fn name, the encapsulating
parentheses, etc.):
That's because I screwed up! I gave you the wrong function, f instead of g .
Here's g:
g - function(...){
sapply(as.list(match.call())[-1],deparse)
}
and the example should now work.
