我可以使用R中的下拉菜单制作线图而不使用Shiny或Plotly吗?

我想制作一个简单的销售报告折线图,显示从下拉菜单中给定产品的产品销售额。我使用情节和闪亮的方式做了一个报告,但我无法找到与同事分享报告的方法,而无需使用Shiny Server或Shinyapps.IO。理想情况下,我想要一个独立的html文件,但我找不到一种方法来将交互式图形插入R Markdown。

以下是一个示例数据框:

df = data.frame(month=rep_len(1:12, length.out=12*5), product=rep(1:5, each=12),sales=rnorm(12*5,100,50)) 

以下建议几乎可行,但下拉列表与正确的变量

不对应
set.seed(42)
library(plotly)

## Create random data. cols holds the parameter that should be switched
l <- lapply(1:100, function(i) rnorm(100))
df <- as.data.frame(l)
cols <- paste0(letters, 1:100)
colnames(df) <- cols
df[["c"]] <- 1:100


p <- plot_ly(df,
      type = "scatter",
      mode = "lines") %>% 
      add_lines(x = ~c, y=~df[[cols[[1]]]], name = cols[[1]])
## Add arbitrary number of traces
for (col in cols) {
  p <- p %>% add_lines(x = ~c, y = df[[col]], name = col, visible = FALSE)
}
p <- p %>%
    layout(
      title = "Dropdown line plot",
      xaxis = list(title = "x"),
      xaxis = list(title = "y"),
      updatemenus = list(
        list(
            y = 0.7,
            ## Add all buttons at once
            buttons = lapply(cols, function(col) {
              list(method="restyle", 
                args = list(
                  "visible", cols == col),
                  label = col)
            })
        )
      )
    )

print(p)

选择变量b2显示a1和v100的行。

selecting b2 shows the line for a1 and v100

虽然选择c3显示a1的行,d4代表b2,等等。看起来顺序是shiftet 2列。

selecting c3 shows the line for a1

以下示例完全符合您的要求,可以嵌入到RMarkdown中,然后转换为可以脱机查看或托管在服务器上的独立HTML页面:

## Create random data. cols holds the parameter that should be switched
l <- lapply(1:100, function(i) rnorm(100))
df <- as.data.frame(l)
cols <- paste0(letters, 1:100)
colnames(df) <- cols
df[["c"]] <- 1:100

## Add trace directly here, since plotly adds a blank trace otherwise
p <- plot_ly(df,
      type = "scatter",
      mode = "lines",
      x = ~c, 
      y= ~df[[cols[[1]]]], 
      name = cols[[1]])
## Add arbitrary number of traces
## Ignore first col as it has already been added
for (col in cols[-1]) {
  p <- p %>% add_lines(x = ~c, y = df[[col]], name = col, visible = FALSE)
}

p <- p %>%
    layout(
      title = "Dropdown line plot",
      xaxis = list(title = "x"),
      yaxis = list(title = "y"),
      updatemenus = list(
        list(
            y = 0.7,
            ## Add all buttons at once
            buttons = lapply(cols, function(col) {
              list(method="restyle", 
                args = list("visible", cols == col),
                label = col)
            })
        )
      )
    )

print(p)

不,这就是Shiny的观点 - 你有一个与R服务器的实时会话。如果您想将结果完全放在html文件中,您可能想要预先制作所有图表,然后显示降价文件的结果。我相信您可以使用bsselectR包在markdown中使用下拉菜单。
