R Loops & Conditionals: Complete Guide

In R language, you can use if statements for conditional evaluation, and control loops with for loops, while loops, repeat loops, and similar statements.

1. Make conditional statements using if statements.

x <- 10
if (x > 5) {
  print("x大于5")
} else {
  print("x小于等于5")
}

1. Control the loop using a for loop.

for (i in 1:5) {
  print(i)
}

1. Control the loop using a while loop.

i <- 1
while (i <= 5) {
  print(i)
  i <- i + 1
}

1. Use the repeat loop for loop control.

i <- 1
repeat {
  print(i)
  i <- i + 1
  if (i > 5) {
    break
  }
}
