Many thanks Bert for being so cooperative.
Deviding the data into small bites would be
a good suggestion but I will wait first to see
If someone else may have another idea.
Many thanks

Perhaps some modification of
masterList <- list()
for( dfnum in seq_along(ListOfDFs)){
masterList <- rbind(masterList, ListOfDFs[[dfnum]])
}
masterList

1. "Similar" or "same" column names. The former is probably not going to
work.
2. Manipulations with data frames can consume a lot of memory. rbinding
8000 data frames is likely to be very slow with lots of time swapping
memory around(???). Perhaps try taking smaller bites (say 1000 at a time)
Hi dear Patrick ,
Thanks for your replay. Below is a reproducible example . First, I generated
two similar Dfs with one column contains the interval. Then, I put the 2 dfs
in a list. Now, converting this list into df provides different results
depending on the code. See below for more
You didn't provide a reproducible example for testing (or post in
plain text), but lubridate has an as.interval() function. You'll need
to be able to extract the start time, though, for use in the function.

Hi dear group ,
I have list of datframes with similar column names. I want to rebind all
dataframes so I have a single dataframe. One of the column's in each df is of
'interval' time class which was generated from 'lubridate' package.
The problem is that when I convert the list of dfs into a
