Good day,
My question is: Does the lapply function guarantee a particular sequence in
which elements are mapped? And, are we guaranteed that lapply will always be
sequential (i.e. never map elements in parallel) ?
No.
The reason I ask is if I use lapply with the mapping function set to
something that has side-effects that need to be executed in a particular
sequence.
Use a for loop.
If this is not possible, is there an alternate method other than using a for
loop?
while or repeat.
