R语言 获取指定范围内的数字列表 – seq.int() 函数
R语言中的 seq.int() 函数用于返回指定范围内的数字列表。
语法: seq.int(from, to, by)
参数:
from: 指定范围 from
to: 指定范围 to
by: 指定的数字,通过它跳过返回的数字。
例1 :
# R program to illustrate
# seq.int function
# Calling seq.int() function
seq.int(0, 5)
seq.int(-2, 6)
seq.int(-3, 7)
seq.int(-7, 0)
输出
[1] 0 1 2 3 4 5
[1] -2 -1 0 1 2 3 4 5 6
[1] -3 -2 -1 0 1 2 3 4 5 6 7
[1] -7 -6 -5 -4 -3 -2 -1 0
例2 :
# R program to illustrate
# seq.int function
# Calling seq.int() function
seq.int(2, 10, by = 2)
seq.int(0, 5, by = 1)
seq.int(5, 50, by = 10)
输出
[1] 2 4 6 8 10
[1] 0 1 2 3 4 5
[1] 5 15 25 35 45
