刚开始使用R并试图找出在创建“汇总表”时能满足我需求的因素。我习惯于在SPSS中使用自定义表,而gmodels包中的CrossTable函数几乎可以让我获得所需的位置;更不用说对于刚从R开始的人来说很容易导航。
也就是说,似乎Hmisc表非常擅长创建各种摘要并导出到LaTex(最终我需要做的事情)。
我的问题是:1)您可以在Hmsic页面轻松创建下表吗? 2)如果是这样,我可以互动变量(列中的2)吗?最后3)我可以访问显着性检验的p值(卡方)。
提前致谢,
布洛克

gmodels包有一个名为CrossTable
的函数,对于那些习惯于SPSS和SAS输出的人来说非常好用。试试这个例子:
library(gmodels) # run install.packages("gmodels") if you haven't installed the package yet
x <- sample(c("up", "down"), 100, replace = TRUE)
y <- sample(c("left", "right"), 100, replace = TRUE)
CrossTable(x, y, format = "SPSS")
这应该为您提供与您在问题上显示的输出相同的输出,非常SPSS-y。 :)

如果您来自SPSS,您可能会对Deducer包(http://www.deducer.org)感兴趣。它具有列联表函数:
> library(Deducer)
> data(tips)
> tables<-contingency.tables(
+ row.vars=d(smoker),
+ col.vars=d(day),data=tips)
> tables<-add.chi.squared(tables)
> print(tables,prop.r=T,prop.c=T,prop.t=F)

您可以使用xtable包获取计数并测试乳胶或html:
> library(xtable)
> xtable(drop(extract.counts(tables)[[1]]))
> test <- contin.tests.to.table((tables[[1]]$tests))
> xtable(test)
