r loops

# 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
