我想从 rpivotTable 库生成一个数据透视表带有垂直滚动条以允许查看长输出。

数据透视表是在 RStudio 中用 knitr 生成的,嵌入在 flexdashboard 模板中。

我没有使用 Shiny 的仪表板,问题已经解决,我的只是用 knitr 生成的 html 仪表板

在你给我减号之前......我真的试过了,认为可能没有记录设置:我的 Rmd 代码部分如下所示(在两种情况下滚动都没有结果):

---
title: "Untitled"
output:
flexdashboard::flex_dashboard:
orientation: columns
vertical_layout: fill
---

```{r setup, include=FALSE}
library(flexdashboard)
library(rpivotTable)

state_table <- data.frame(key=c("CA", "NY", "WA", "ON", "QU"),
name=c("California", "new York", "Washington", "Ontario", "Quebec"),
country=c("USA", "USA", "USA", "Canada", "Canada"))

month_table <- data.frame(key=1:12,
desc=c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"),
quarter=c("Q1","Q1","Q1","Q2","Q2","Q2","Q3","Q3","Q3","Q4","Q4","Q4"))

prod_table <- data.frame(key=c("Printer", "Tablet", "Laptop"),
price=c(225, 570, 1120))

# Function to generate the Sales table

gen_sales <- function(no_of_recs) { # Generate transaction data randomly
loc <- sample(state_table$key, no_of_recs, replace=T, prob=c(2,2,1,1,1))
time_month <- sample(month_table$key, no_of_recs, replace=T)
time_year <- sample(c(2012, 2013), no_of_recs, replace=T)
prod <- sample(prod_table$key, no_of_recs, replace=T, prob=c(1, 3, 2))
unit <- sample(c(1,2), no_of_recs, replace=T, prob=c(10, 3))
amount <- unit*prod_table[prod,]$price

sales <- data.frame(month=time_month,
year=time_year,
loc=loc,
prod=prod,
unit=unit,
amount=amount)

# Sort the records by time order

sales <- sales[order(sales$year, sales$month),]

row.names(sales) <- NULL
return(sales)
}

# Now create the sales fact table

sales_fact <- gen_sales(100000)


```

Column {data-width=650}
-----------------------------------------------------------------------

### Table

```{r}
library(rpivotTable)
rpivotTable(
sales_fact,
rows = c("year","month"),
cols = c("prod"),
aggregatorName = "Sum",
vals = "amount",
rendererName = "Heatmap",
height = "600px",
overflow = "scroll")

```

Column {data-width=350}
-----------------------------------------------------------------------

### Chart B

```{r}

```

### Chart C

```{r}

```

我将非常感谢任何指示如何实现 rpivottable 的垂直滚动。

最佳答案

这是一个更简单的选择:

  1. 将顶部保留为:

    ---
    title: "Untitled"
    output:
    flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
    ---
  2. 然后只需在数据透视表 block 之后添加一个 CSS block ,如下所示:

    .rpivotTable{ overflow : scroll; }
  3. 这个 block 的头可以是这样的:

    {css, 数据透视表 CSS, echo = FALSE}

希望这对您有所帮助!
