将迷你图表添加到表格中

Question

我试图将我的所有数据运算转移到Rmarkdown而不是SPSS + Excel,但无法弄清楚如何创建带有附加图的表.

在Excel中,这可以使用迷你图功能完成,或者像我一样,只需创建一个图表并非常准确地放置它.

上表是使用Tables包(和Pander)中的表格函数创建的.并粘贴到Excel中以创建图形(以及图形的标题).

library(tables)
library(pander)
pander( #convert table to rmarkdown table
  tabular( 
  (Species + 1) ~ (n=1) + Format(digits=2) *
         (Sepal.Length + Sepal.Width) * (mean + sd), 
  data = iris),
  caption = "Table 1. Iris") #Heading for table

有没有人创造过这样的东西？也许使用gridExtra包解决方法,虽然我怀疑包可以匹配表和图.

编辑 - 迄今为止的解决方案.
HTML已完成.在那里用pdf中途.对于doc,我认为不可能(复制粘贴到Excel).

HTML表
首先,所以R知道我是否正在渲染html,pdf或doc.out_type取值:"html","pdf"和"docx".我可以在if语句中使用这个对象.

out_type <- knitr::opts_knit$get("rmarkdown.pandoc.to")

现在吧:

    if(out_type == "html"){ #if output is html then:
        my_table$Mean_Sepal_Length <- paste0( #I have a table saved as a dataframe. I add a column to it called Mean_Sepal_Length
"<span style=' width: 100%; display: flex;'><span style='display: inline-block; border-radius: 3px; padding-right: 0; background-color: #00457C; width:", #create the bar
        MEAN_SEPAL_L_OBJECT, #set the with of the bar. I have an object with these proportions
"%; margin-right: 5px;'>&nbsp;</span><span>", MEAN_SEPAL_L_VARIABLE, "%</span></span>") #finally add the value behind the bar.
    }

也可以有两列.

在这里,我有一个比例表,我有两个对象,男性和女性的比例.

    my_table$male_female <- paste0(
"<span style=' width: 100%; display: flex;'><span>", MALE_BAR, #the proportion of males
 "%</span><span style='display: inline-block;border-top-left-radius: 3px; border-bottom-left-radius:3px; padding: 0; background-color: #00457C; width:", MALE_BAR, #width of the bar for males
 "%; margin-left: 5px;'></span><span style='display: inline-block; border-top-right-radius: 3px; border-bottom-right-radius:3px; padding:0; background-color: #AC1A2F; width:",
 FEMALE_BAR, #width of bar for females
 "%;margin-right: 5px;'></span><span>", FEMALE_BAR, #proportion of females
 "%</span></span>")

当然,如果你愿意的话,你也可以把数字放在栏内,但是当栏很小时你就会有问题.

PDF格式
我还没有达到目标.这是我到目前为止的解决方案:

\begin{tabular}{>{$\rhd$ }lrl}
Loop at line 151 in divergence  & \mybar{3.420}\\
Loop at line 1071 in radiation  & \mybar{3.270}\\
scalar face value               & \mybar{3.090}\\
Loop at line 102 in get         & \mybar{1.700}\\
get sensible enthalpy           & \mybar{1.250}\\
\end{tabular}

它看起来不太好.我是Latex的新手.我仍然需要找出如何将数字放在条形后面.以及如何将它放入我的函数中的if语句中.如果HTML然后:if pdf then ...

我希望这可以帮助别人.但是请考虑一下这个帖子中提到的包.他们很优秀,我的解决方案非常基于他们.我只是无法得到我正在寻找的包,所以我手动完成.

只需在上一个答案中添加一个迷你示例.希望能帮助到你.

```{r results="asis"}

library(dplyr)
library(formattable)
library(sparkline)


res <- 
  iris %>% 
  group_by(Species) %>% 
  summarise(N=n(),
            SL_Mean=round(mean(Sepal.Length),3),
            SL_SD=round(sd(Sepal.Length),3),
            SW_Mean=round(mean(Sepal.Width),3),
            SW_SD=round(sd(Sepal.Width),3)) %>%
  mutate(sparkline = as.character(Species))

#using formattable
formattable(
  res,
  list(
    SL_Mean=color_bar("pink", proportion),
    "sparkline"=function(z){
      sapply(
        z,
        function(zz){
          knitr::knit(
            text = sprintf(
              '`r sparkline(c(%s))`',
              paste0(
                iris[which(iris$Species == zz),"Sepal.Length"],
                collapse=","
              )
            ),
            quiet = TRUE
          )
        }
      )
    }
  )
)


```

此外,我认为一个非rmarkdown实例可能会让一些人感到高兴.

library(dplyr)
library(formattable)
library(sparkline)


res <-
  iris %>%
  group_by(Species) %>%
  summarise(N=n(),
            SL_Mean=round(mean(Sepal.Length),3),
            SL_SD=round(sd(Sepal.Length),3),
            SW_Mean=round(mean(Sepal.Width),3),
            SW_SD=round(sd(Sepal.Width),3)) %>%
  mutate("sparkline" = as.character(Species))

#using formattable
ft <- formattable(
  res,
  list(
    SL_Mean=color_bar("pink", proportion),
    "sparkline"=function(z){
      sapply(
        z,
        function(zz){
          sprintf(
            '<span class="sparkline-bar">%s</span>',
            paste0(
              iris[which(iris$Species == zz),"Sepal.Length"],
              collapse=","
            )
          )
        }
      )
    }
  )
)

library(htmlwidgets)
browsable(
  attachDependencies(
    tagList(
      onRender(
        as.htmlwidget(ft),
        "function(el,x){$('.sparkline-bar').sparkline('html',{type:'bar'});}"
      )

    ),
    htmlwidgets:::widget_dependencies("sparkline","sparkline")
  )
)

Answer 2

我认为你需要的是可格式化的包.还有一个将迷你图与格式表混合的例子,但我无法根据您的需要进行调整.

```{r cars}

library(dplyr)
library(formattable)

res <- 
  iris %>% 
  group_by(Species) %>% 
  summarise(N=n(),
            SL_Mean=round(mean(Sepal.Length),3),
            SL_SD=round(sd(Sepal.Length),3),
            SW_Mean=round(mean(Sepal.Width),3),
            SW_SD=round(sd(Sepal.Width),3))

#using formattable
formattable(res,
            list(
              SL_Mean=color_bar("pink", 0.5)))
