For short:
1. I wonder if you cannot make the two steps one and hence only need one
lapply anway.
2. Why not just try out?
3. If it does not work, ordinary loops may be able to.

Dear all,
I want for a given data set to call a funciton many time. That bring us all to
the notion of lapply (or any other variance). My problem is that this data set
should also be created from another lapply
As for example
DataToAnalyse<- return_selected_time_interval(TimeStamps,Time[[1]],
Time[[2]]) # Where Time[[1]] and Time[[2]] are lists
return(lapply(do_analysis(DataToAnalyse)))
as you can see the DataToAnalyse should be also an lapply. For the list of give
Time (Time[[1]] and Time[[2]]) should create a list DataToAnalyse.
My concern though is that the DataToAnalyse for all the Time is huge so I was
looking for something memory efficient that can do something like that
Create Data To Analyse-->feed it into do_analysis-->store result into a
list(The result is small). Repeat that sentence for all Time
How I can do something like that efficiently in R?
