如何解决仪表板在闪亮的应用程序内运行，但不在Flexdashboard上运行
我正在尝试将闪亮的交互式工作表合并到我现有的flexdashboard中。
这是使用dput（）函数创建的数据结构
library(dplyr)
#>
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#>
#> filter,lag
#> The following objects are masked from 'package:base':
#>
#> intersect,setdiff,setequal,union
library(tibble)
dat <- tibble::tribble(
~group,~var1,~var2,"A","foo",NA,"bar","B","C","D","E","bar"
)
expected_output <- tibble::tribble(
~group,"bar"
)
expected_output
#> # A tibble: 5 x 3
#> group var1 var2
#> <chr> <chr> <chr>
#> 1 A foo bar
#> 2 B foo <NA>
#> 3 C foo bar
#> 4 D <NA> bar
#> 5 E foo bar
数据是关于8个不同的离线导航应用的评论中的常用词。
我使用以下代码创建了闪亮的小型应用程序（有效）
structure(list(words1 = structure(c(1L,10L,19L,20L,7L,8L,3L,15L,2L,9L,11L,14L,12L,4L,5L,6L,16L,18L,17L,13L

),"download","just","now","time","tom","tomtom","work","year"),pct2 = c(69.1,32.9,27.3,25,21.4,20,16.6,16.2,14.7,13.1,13,12.7,12.2,11.8,10.4,10.3,10.2
),words3 = structure(c(1L,13L,7L),"copilot","new","version",pct3 = c(57.9,45.7,30.1,21.7,19.5,19,18.5,18,17.1,16.7,14.9,14.6,14,12.5,11.5,10.9,10.6,10.5),words4 = structure(c(1L,17L),"doesnt","even","find","navmii","tri",pct4 = c(56.1,41.2,36.5,32.5,22.6,20.9,18.9,15.8,14.1,12.9,12.4,11.7,11.3,11.1,10.1),words5 = structure(c(1L,"best","gps","love","nice","offlin","sygic",pct5 = c(39.7,23.5,20.5,19.3,13.8,10.2,8.6,7.7,6.7,6.1,6,5.9,5.5,5.1,5,4.9),words6 = structure(c(1L,12L),"help","thank","travel",pct6 = c(37.4,23,20.7,13.3,13.2,9.1,6.5,5.6,5.4,4.9,4.8,4.6),words7 = structure(c(1L,2L),"drive","googl","traffic","waze",pct7 = c(57.9,32.4,24.6,20.3,15.9,15.2,12.8,12.3,10,9.9,9.7,9.1),words8 = structure(c(1L,3L),"better",pct8 = c(44.6,39.3,25.2,22.3,15.4,12.6,8.8,8.7,7.3,7.1,6.8,6.6,6.4,5.5)),class = "data.frame",row.names = c(NA,-20L))
现在我正在尝试使用以下代码，并使用以下代码将其合并到我现有的flexdashboard中，但是我无法使其正常工作。

如果我运行rmarkdown：render（“ filename.Rmd”），则会收到以下错误：未提供html_dependency的路径
如果我运行rmarkdown：run（“ filename.Rmd”），我得到的应用程序将不会显示任何过滤器或图表。我想尽可能地运行render函数，因为我以前用过以前的flexdashboard来做到这一点，如果将仪表板导出到.html文件，一切看起来都会更好。
解决方法
诀窍是仅使用{r}而忽略include = FALSE。另外，我已经更正了列和侧栏的定义。
