tableOne

#以“trt作为分层变量”，factorVars 定义因子型变量

print(tableOne,showAllLevels = TRUE)

#showAllLevels = TRUE显示所有水平的频数和百分比

#默认对定量变量进行t检验或方差分析，对分类变量进行卡方检验，并输出P值

tableOne$CatTable

#仅输出分类变量结果

tableOne$ContTable

#仅输出定量变量结果

summary(tableOne$CatTable)

#分类变量统计描述详细信息

summary(tableOne$ContTable)

#定量变量统计描述详细信息

print(tableOne,nonnormal= c("bili","chol","copper","alk.phos","trig"),

exact= c("status","stage"), showAllLevels = TRUE )

#nonnormal指定非正态变量，对其进行wilcox.test或 kruskal.test；exact指定进行fisher.test的变量

print(tableOne,nonnormal= c("bili","chol","copper","alk.phos","trig"),

exact= c("status","stage"), showAllLevels = TRUE，quote = TRUE)

#将输入结果复制到txt文件中

#打开Excel，依次点击“数据”菜单——“自文本”——“分隔符号”——“空格”——“确定”，即可将结果输入到excel表格中。
