如何在我的 R 数据集上应用 propt.test？
How to apply propt.test on my dataset in R?
我试图分析 Aids2，我想将 "prop.test" 应用于男性与女性中通过 "hs" 方法感染的比例。我该怎么做？

您可以创建一个包含按性别分类的 hs/其他感染计数的数据集，并应用 prop.test 函数
library(dplyr)
library(tidyr)
df_counts = df %>%
mutate(T.categ2 = ifelse(T.categ == "hs", T.categ, "other")) %>% # flag hs or other
count(sex, T.categ2) %>% # count how many times each sex was infected by hs or other
spread(T.categ2, n, fill = 0) %>% # reshape dataset
mutate(Total = hs+other) # count totals
# see how your aggregated dataset with counts looks like
df_counts
# # A tibble: 2 x 4
# sex hs other Total
# <chr> <dbl> <dbl> <dbl>
# 1 F 0 4.00 4.00
# 2 M 78.0 16.0 94.0
# apply prop test using the appropriate columns
prop.test(df_counts$hs, df_counts$Total)

您可以创建一个包含按性别分类的 hs/其他感染计数的数据集，并应用 prop.test 函数
library(dplyr)
library(tidyr)
df_counts = df %>%
mutate(T.categ2 = ifelse(T.categ == "hs", T.categ, "other")) %>% # flag hs or other
count(sex, T.categ2) %>% # count how many times each sex was infected by hs or other
spread(T.categ2, n, fill = 0) %>% # reshape dataset
mutate(Total = hs+other) # count totals
# see how your aggregated dataset with counts looks like
df_counts
# # A tibble: 2 x 4
# sex hs other Total
# <chr> <dbl> <dbl> <dbl>
# 1 F 0 4.00 4.00
# 2 M 78.0 16.0 94.0
# apply prop test using the appropriate columns
prop.test(df_counts$hs, df_counts$Total)
