I am using R currently and I want to know how can I label the list objects when I declare a list. For example: return(list(xhat,alpha,beta)), and xhat, alpha and beta are themselves arrays. I want to give each an appropriate label.
我目前正在使用R，我想知道如何在声明列表时标记列表对象。例如:return(list(xhat,alpha,beta))，而xhat、alpha和beta本身就是数组。我想给每个人一个合适的标签。
Thank you.

For simple cases Michael's answer will work. Sometimes though you have a vector of names my_names which you would like to use to name/rename the output. There are at least three ways:
对于简单的例子，迈克尔的答案是有效的。有时，虽然有一个mynames _names向量，但您希望使用它来命名/重命名输出。至少有三种方法:
-
use
names<-:使用名称< - - - - - -:
out <- list(xhat,alpha,beta) names(out) <- my_names out -
use
setNames():使用setNames():
setNames(out, my_names) -
use
structure():利用结构():
structure(out, names=my_names)

All you need is list(x=xhat, a=alpha, b=beta)
你只需要列表(x=xhat, a=alpha, b=beta)
