I want to apply a sample function to a nested list (I will call this list `bb`) and I also have a list of numbers (I will call this list `k`) to be supplied in the sample function. I would like each of the numbers in k to iterate through all the values of each list in bb. How to do this using `mapply` or `lapply`?
Here are the data: k <- list(1,2,4,3) #this is the list of numbers to be supplied in the ` sample.int` function b1 <- list(c(1,2,3),c(2,3,4),c(3,4,5),c(4,5,6)) #The first list of bb b2 <- list(c(1,2),c(2,3),c(3,4),c(4,5), c(5,6)) #The second list of bb bb <- list(b1,b2) #This is list bb containing b1 and b2 whose values are to be iterated through ``` I created this `mapply` function but it didn't get the expected outcome: mapply(function(x, y) { x[sample.int(y,y, replace = TRUE)] }, bb,k, SIMPLIFY = FALSE) This only returns 10 output values but I would like each number of k to loop through all values of the two lists in `bb` and so there should be 10*2 outputs for the two lists in `bb`. I might be using `mapply` in the wrong way and so I would appreciate if anyone can point me to the right direction!
