# Basic syntax of for loop:
for (i in sequence) {
code to be repeated
}
# Example usage of for loop:
for (i in 1:5) {
print(i)
}
# Basic syntax of while loop:
while (condition_is_true) {
code to be repeated
}
# Example usage of while loop:
i = 1
while (i < 5) { # True while i is less than 5
print(i)
i = i + 1 # Increment i each iteration
}
# Note, you can completely exit from a loop with "break", or skip to the
# next iteration of a loop with "next"
# Example of next and break:
for (i in 1:5) {
if (i == 2) { # Skip to next iteration if i = 2
next
}
if (i == 4) { # Exit loop entirely if i = 4
break
}
print(i)
}
# Returns:
[1] 1
[1] 3
