当我创建“ add_p()的自定义pvalue函数”时,我试图调整p值的位数,但是发现“舍入”函数不起作用。 (请参见代码“ result $ p <-round(result $ p,3)”)
此外,我发现我无法更改汇总表中计数数字百分比的数字。
ttest1 <- function(data, variable, by, ...) {
result <- list()
result$p <- stats::t.test(data[[variable]] ~ data[[by]])$statistic
result$p <- round(result$p, 3)
result$test <- "t test"
result
}
ttest2 <- function(data, variable, by, ...) {
result <- list()
result$p <- stats::t.test(data[[variable]] ~ data[[by]])$p.value
result$p <- round(result$p, 3)
result$test <- "t test"
result
}
add_p_ex1 <-trial[c("age","grade", "response", "trt")] %>%
tbl_summary(by = trt,
statistic = list(all_continuous() ~ "{mean} ± {sd}",
all_categorical() ~ "{n} ({p})"),
digits = list(all_continuous() ~ c(2, 2))) %>%
add_p(test = list(all_continuous() ~ "ttest1", all_categorical() ~ "chisq1")) %>%
modify_header(p.value = md("**t/X2**"))
add_p_ex2 <-
tbl_summary(by = trt,
statistic = list(all_continuous() ~ "{mean} ± {sd}",
all_categorical() ~ "{n} ({p})"),
digits = list(all_continuous() ~ c(2, 2))) %>%
add_p(test = list(all_continuous() ~ "ttest1", all_categorical() ~ "chisq2"))
tbl_merge(list(add_p_ex1, add_p_ex2)) %>%
as_gt(include = -tab_spanner) %>%
cols_hide(columns = vars(stat_1_2, stat_2_2))

首先,请您在您制作的桌子上称赞我,我印象深刻!
要更改表中p值的格式,请使用add_p(pvalue_fmt=)
参数传递函数。该函数应采用数字矢量,并返回格式化/四舍五入的字符矢量。
我们仍在为用户修改tbl_summary()
输出中百分比的默认格式的最佳方法。在gtsummary的开发版本中,我们引入了主题,使您可以指示输出显示方式的首选项。我在下面提供了一个示例,如果您想了解更多信息,这是小插图的链接。 (仅供参考,您还可以设置主题的p值格式功能。)
