Rmarkdown docx中的R饼图

Question

I have a data and want to create a pie chart in Rmarkdown word_document.
Here is my data:

dt <- data.table::fread("
        TravelArea DayCounts  
            Others     98254  
             China    298705 
               USA     39048  
         SouthAsia    127046  
            Europe    114529  
        MIDAmerica      4270  
               AUS     21917 
            ENAsia    361727 
             Local   1819977 
            Africa      2473  
 AsiaPacificIsland      2943 
            ESAsia     25208  ")

My code in Rmarkdown is:

```{r echo=FALSE, message=FALSE, warning=FALSE}
plotly::plot_ly(dt, labels = ~ TravelArea, values = ~ DayCounts, type = 'pie', 
                 textposition = 'inside', 
                 textinfo = 'label+percent', 
                 insidetextfont = list(color = '#FFFFFF'), 
                 hoverinfo = 'text', 
                 text = ~paste(TravelArea, DayCounts),
                 marker = list(colors = colors,                                                                                                                               line = list(color = '#FFFFFF', width = 1)),
                 showlegend = T) %>%
    layout(title = 'Figure C.1.1',
           xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE),
           yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE))
```

However, this cannot output to docx . How can I create a pie chart that can output and present properly to word_document .

Answer 1

you can try solution given on this link: Plotly as png in knitr/rmarkdown .

```{r echo=FALSE, message=FALSE}
library(plotly)

dt <- data.table::fread("
         TravelArea DayCounts  
             Others     98254  
              China    298705 
                USA     39048  
          SouthAsia    127046  
             Europe    114529  
         MIDAmerica      4270  
                AUS     21917 
             ENAsia    361727 
              Local   1819977 
             Africa      2473  
  AsiaPacificIsland      2943 
             ESAsia     25208  ")



p <- plot_ly(dt, labels = ~ TravelArea, values = ~ DayCounts, type = 'pie', 
             textposition = 'inside', 
             textinfo = 'label+percent', 
             insidetextfont = list(color = '#FFFFFF'), 
             hoverinfo = 'text', 
             text = ~paste(TravelArea, DayCounts),
             marker = list(colors = colors,                                                                
             line = list(color = '#FFFFFF', width = 1)),
             showlegend = T)  %>%
             layout(title = 'Figure C.1.1',
             xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE),
             yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE))

tmpFile <- tempfile(fileext = ".png")
export(p, file = tmpFile)

```
