Here we are explaining how to write an R program to combine two given lists into one list by using a built-in combine function c(). This function helps to combine its arguments to form a list, where all the arguments are related to a common type and the type of the return value, The syntax of this function is
c(…) # Where ... indicates object to be concatenate
In this R program, we directly give the values to a built-in function c(). Here we are using variables lst1 and lst2 for holding the list elements of two different types. Call the function c() for merging the two lists and assigning them to a list variable merge_lst.
STEP 1: Assign variables lst1,lst2 with a list of two different types
STEP 2: Print the original lists
STEP 3: Merge the two lists by calling the combine function as c(lst1,lst2)
STEP 4: Assign merged lists into the variable merge_lst
STEP 5: Print the merged list merge_lst
lst1 = list(5,2,1)
lst2 = list("Red", "Green", "Black")
print("Original lists:")
print(lst1)
print(lst2)
print("Merge the lists:")
merge_lst = c(lst1, lst2)
print("New merged list:")
print(merge_lst)
[1] "Original lists:" [[1]] [1] 5 [[2]] [1] 2 [[3]] [1] 1 [[1]] [1] "Red" [[2]] [1] "Green" [[3]] [1] "Black" [1] "Merge the lists:" [1] "New merged list:" [[1]] [1] 5 [[2]] [1] 2 [[3]] [1] 1 [[4]] [1] "Red" [[5]] [1] "Green" [[6]] [1] "Black"
