Julian's questions

我有以下应用程序：

library(bslib)
library(shiny)

id <- "hi"
ns <- NS(id)
page_navbar(
  id = ns("navbar"),
  title = "Example App",
  sidebar =  sidebar(
    id = ns("sidebar"),
    open = "open"
  ),
  nav_panel(
    title = "Overview", 
    h1("Overview")),
  nav_panel(
    title = "Table", 
    h1("table"))
)
)

我想在右侧添加第二个（关闭的）侧边栏。根据可能链接的文档page_fillable()，当我坚持时，我的方法不会让我走上正确的轨道page_navbar。有什么提示吗？

我的做法：

page_navbar(
  layout_sidebar(
    sidebar = sidebar("Left sidebar"),
    layout_sidebar(
      sidebar = sidebar("Right sidebar", position = "right", open = FALSE),
    )
  ),
  nav_panel(
    title = "Overview", 
    h1("Overview")),
  nav_panel(
    title = "Table", 
    h1("table"))
  )
)

我想从日历年变量（此处为 1991 到 2001）创建日历年的开始日期和结束日期，并找到了解决方案：

library(lubridate)
library(dplyr)
df <- tibble(calendar_year = seq(1991, 2001, 1)) 

df |>
  mutate(
    calendar_year_start_date = ymd("1991-01-01") + 
      years(calendar_year - 1991),
    calendar_year_end_date = ymd("1991-12-31") + 
      years(calendar_year - 1991 )
  )

结果：

# A tibble: 11 × 3
   calendar_year calendar_year_start_date calendar_year_end_date
           <dbl> <date>                   <date>                
 1          1991 1991-01-01               1991-12-31            
 2          1992 1992-01-01               1992-12-31            
 3          1993 1993-01-01               1993-12-31            
 4          1994 1994-01-01               1994-12-31            
 5          1995 1995-01-01               1995-12-31            
 6          1996 1996-01-01               1996-12-31            
 7          1997 1997-01-01               1997-12-31            
 8          1998 1998-01-01               1998-12-31            
 9          1999 1999-01-01               1999-12-31            
10          2000 2000-01-01               2000-12-31            
11          2001 2001-01-01               2001-12-31   

有用; 但我正在寻找更优雅的解决方案。谢谢您的任何提示！
