我英语不好。所以请您耐心等待并进行编辑。
我分析了韩国的人口普查数据。我使用“adaboost”作为分析方法，并为每个城市实现了 adaboost。目标变量、自变量、公式、选项、观测次数等，各个城市都是一样的。没有区别。我做了一个宏，为城市一一实现adaboost。在开始分析下一个城市之前，宏会删除除自身之外的所有对象。
我发现随着时间的推移，平均处理速度越来越慢。我的意思是，1-30 的城市平均所需时间约为 10 分钟，但 80-100 的城市则变为 25 分钟。所以我终止了 R session 并重新打开。我从第80个城市重新运行宏，然后第80-100个城市的平均时间减少到10分钟。
为什么会发生这种情况？我怎么解决这个问题？我需要你的帮助。提前致谢。
<小时/>r代码和宏如下。 'sgg' 宏变量表示城市代码。目标变量有六类。所以我使用“one-others”方法进行多类分类。

最佳答案
我的理解是，R 是作为写时复制实现的。
举个例子:
X <- 1:1000
y <- x # no copy made. x & y share the reference
y[1] <- 8 # now a copy is made.
如果 x 不断增长，副本所需的时间会越来越长，并且脚本速度会变慢。 我对宏变量不太熟悉，但我怀疑类似的事情正在发生。 如果您正在使用列表，则每次向列表添加新元素时，所有内容都会被重新复制。
y <- list()
y$this <- 1:5
y$that <- 6:10 # now every thing was recopied.
因此最好先分配。它确实有助于性能。
y <- vector("list", 2)
y[[1]] <- 1:5
y[[2]] <- 6:10
这些幻灯片非常好:a link看看吧!
