是否可以通过R中的函数在某个范围之间运行每个可能的值组合？例如，假设我有四个变量
x1 = seq(from = 0.1, to = 35, by = 0.1)
x2 = seq(from = 0.1, to = 35, by = 0.1)
x3 = seq(from = 1, to = 20, by = 0.1)
x4 = seq(from = 1, to = 100, by = 1)
并希望将它们输入到函数中：
kk <- my.func(x1,x2,x3,x4)
我的问题：是否有可能将四个变量中每个值的每个可能组合合并到函数中？例如：
kk <- my.func(x1 = 0.1, x2 = 0.1, x3 = 1, x4 = 1)
kk <- my.func(x1 = 0.1, x2 = 0.2, x3 = 1, x4 = 1)
依旧......
我意识到这将导致大量的迭代，但我仍然希望看到它可以完成的方式。
