当我

在 SPSS 中进行操作时，结果是 48.5% 男性 (1) 和 51.5% 女性 (2)。
如果我这样做，
round(prop.table(xtabs(test[,2] ~ test[,1], test)),3)
我会得到 49.2% 的男性 (1) 和 50.8% 的女性 (2)，测试数据集有 47.8% 的男性和 52.2% 的女性。
有人知道它们为什么不同以及我如何像 SPSS 中那样设置权重，以便该权重对所有程序都有效，例如 pca...？

When I do
WEIGHT BY wGEDA09pop.
FREQUENCIES VARIABLES=sex
/ORDER=ANALYSIS.
in SPSS, I got 48,5% male (1) and 51,5% female (2) as result.
If I do
round(prop.table(xtabs(test[,2] ~ test[,1], test)),3)
I got 49,2 % male (1) and 50,8 % female (2) with the test dataset 47,8% male and 52,2% female.
Does someone know why they differ and how I can set a weight like in SPSS so that the weight is valid for all procedures e.g. pca... ?
Thanks a lot.
Dominik

通过在该问题的第 2 部分版本中的讨论，很明显调查包中的方法将为分析提供一致的基础。它具有列联表、平均值、分位数、绘图等方法。
With the discussion in your Part 2 version of this question, it became clear that the methods in the survey package would provide a consistent basis for analysis. It has methods for contingency tables, means, quantiles, plotting, etc.
