I'm facing an issue when trying to use the tbl_summary function from the gtsummary package in R. When I run the following code: library(gtsummary) tbl_summary(mtcars) I receive the following error: Error in value[[3L]](cond): Output format 'html' is not supported in...
you'll get an error, because the mtcars data frame does not have a column called class. The mpg data frame is built into the ggplot2 package. Run data(package="ggplot2") to see which data sets come with ggplot2. The mtcars data frame is included in base R. Run data() to see da...

的输出,我们可以使用下面的代码构建我们自己的data.frame。 library(dplyr, w = F) mtcars %>% group_by(cyl) %>% summarize( bind_rows( summarize(group_by(across(everything()), gear), n = n()), tibble(gear = NA, n = n()), ), .groups = "drop", ) #> # A tibble: 11 × 3 ...
