Well I didn't have to make a beast of myself.
So I was able to use purrr to get exactly what I want
It puts all the components of the H5 files into a dataframe regardless of the number of files that I have. I have so many layer that it can get out of hand trying to explain them all. These were files I was give so I have to work with what I have. LOL
data_subsets<- purrr::map2(H5_files, askUser_test_1, h5read)
df <-purrr::map_dfc(data_subsets, "Data", H5Fopen)
Thanks so much for directing me to the correct package.
