如何从R中的变量名列表中调用变量 [英] How to call variables from a list of variable names in R

问题描述

我有一个变量名列表。

list = c("smoke", "ptd", "ht", "ui", "racecat", "visit")

我要绘制一系列图

plot(low[somevariable=="0"] ~ age[somevariable=="0"])

我想用列表中的每个变量名替换一些变量。例如，

I'd like to replace somevariable with each of the variable name in the list. For example,

plot(low[smoke=="0"] ~ age[smoke=="0"])
plot(low[ptd=="0"] ~ age[ptd=="0"])
......
plot(low[visit=="0"] ~ age[visit=="0"])

我尝试创建一个for循环并使用各种方法替换某些变量，例如

I've tried to create a for-loop and use a variety of things to replace somevariable, such as

list[i], paste(list[i]), substitute(list[i]), parse(list[i])

但它们都不起作用。我非常感谢您的帮助。提前致谢。

But none of them works. I would really appreciate some help. Thanks in advance.

推荐答案

您可以尝试：

for(i in list) {
  print(plot(low[get(i) == 0] ~ low[get(i) == 0]))
}
