How to use the counter in a for loop as a number to define a new array

To make it simple: How can i change this expression?

for (i in 1:5){ai=i}

in a way that in "ai" the i is interpreted as a counter and not as a letter "i", so that it creates

a1=1, a2=2,...

I remember a language where you could just use $i to solve this

for (i in 1:5){a$i=i}

but i didn't find the equivalent in R, can someone help me ??

You can use assign

for (i in 1:5) 
  assign(paste0("a", i), i)

but I do not recommend this approach. You can use a vector or a list instead:

a <- list()
for (i in 1:5)
  a <- append(a, i)

Try:

a <- NULL
for (i in 1:5) a[i] <- i

in C++ it is done as:

a[i] = i;

where a[i] signifies i+1th element in array
