trelliscopejs我在使用 Rmarkdown 创建的 html 文件中呈现多个显示时遇到问题。我正在使用self_contained=TRUE以在 html 中呈现显示。问题是只有第一个显示被正确呈现：而其余的被呈现为空格：我正在使用官方教程中的一些示例。整个 .rmd 文件发布在下面：

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
knitr::opts_chunk$set(message = FALSE, warning = FALSE) #suppress ggplot2 warnings
```

```{r}
library(trelliscopejs)
library(ggplot2)
library(dplyr)
```

```{r}
library(tidyr)
library(rbokeh)

d <- mpg %>%
  group_by(manufacturer, class) %>%
  nest() %>%
  mutate(panel = map_plot(data,
    ~ figure(xlab = "City mpg", ylab = "Highway mpg") %>%
        ly_points(cty, hwy, data = .x)))
d
```

```{r}
d %>%
  trelliscope(name = "city_vs_highway_mpg", self_contained = TRUE)
```

```{r}
mpg %>%
  group_by(manufacturer, class) %>%
  summarise(
    mean_city_mpg = cog(mean(cty), desc = "Mean city mpg"),
    mean_hwy_mpg = cog(mean(hwy), desc = "Mean highway mpg"),
    panel = panel(
      figure(xlab = "City mpg", ylab = "Highway mpg",
        xlim = c(7, 37), ylim = c(9, 47)) %>%
        ly_points(cty, hwy,
          hover = data_frame(model = paste(year, model),
            cty = cty, hwy = hwy)))) %>%
  trelliscope(name = "city_vs_highway_mpg", nrow = 1, ncol = 2,
              self_contained = TRUE)
```

```{r}
qplot(x = 0, y = cty, data = mpg, geom = c("boxplot", "jitter")) +
  facet_trelliscope(~ class, ncol = 7, height = 800, width = 200,
    state = list(sort = list(sort_spec("cty_mean"))), self_contained = TRUE) +
  ylim(7, 37) + theme_bw()
```

看来我正在使用最新版本的trelliscopejsasdevtools::install_github("hafen/trelliscopejs")返回：

Skipping install of 'trelliscopejs' from a github remote, the SHA1 (4be901e4) has not changed since last install.
  Use `force = TRUE` to force installation
