for loop r value code example
Example 1: r for loop
# Basic syntax:
for (i in sequence) {
code to be repeated
}
# Example usage:
for (i in 1:5) {
print(i)
}
# Returns:
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
# 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
