在R标记中嵌入标准输出 [英] Embedding plotly output in R markdown
问题描述
有 。然而,RPub似乎并不喜欢这一点。你也可以玩弄 borderwidth
来查看是否可以关闭边框。
完全可以这样说:图表不会显示在预览中。我相信这是一个浏览器限制,因为RStudio不允许发布实时Web内容(还)。
如果您有兴趣并想要一些示例代码, 这里是 2014/04/17 / plotly /rel =nofollow noreferrer>一篇博文,内嵌了Plotly和ggplot2图。希望这可以帮助!披露:我为Plotly工作。

请通过Plotly文档查看此答案的 R Markdown 版本。在R控制台中打印图形对象会创建一个在线图形。例如:
p < - plot_ly(经济学,x =日期,y = uempmed,文件名=r-docs / knitr-example)
如果您使用带有HTML输出的knitr / R Markdown, c $ c> plotly 对象现在将作为iframe嵌入到HTML中。如果您使用R Markdown编写文档,只需打印 p
即可嵌入该图。
您也可以设置宽度和高度代码块参数的情节的宽度和高度。例如:{r,height = 800}设置高度。
如果您使用 Plotly Offline with R Studio ,然后在knitr中打印plotly对象还将包含必要的plotly.js文件以绘制图形:图形在文档内本地呈现。
到将knitr文档转换为独立的HTML文件,使用 knitr :: knit
和 markdown :: markdownToHTML
。例如:
knitr :: knit('plotly-report.Rmd','plotly-report.md')
markdown :: markdownToHTML('plotly-report.md','plotly-report.html')
There is a blog entry which describes embedding from the plotly API for R into R markdown. I just used the code to create the iframe for an html document
When I have the prieview in R studio there is no error message and the iframe is created in the html document. However, it is just empty. Apparently it does not load the content somehow. I did not create the plot in the R API beforehand (but that should not matter as this is just embedding a picture into html) isn't it?
My code in r markdown as it is is currently
```{r}
library("knitr")
library("devtools")
url<-"https://plot.ly/~etpinard/251"
plotly_iframe <- paste("<iframe scrolling='no' seamless='seamless' src='", url,
"/800/600' width='800' height='600'></iframe>", sep = "")
```
`r I(plotly_iframe)`
We had this same issue the first time we published an RPub. Here is your code in a published RPub.
Once it's published at RPubs.com rather than in preview, the graphs should show up. You can test it by using the "open in browser" option in RPubs:
A note. I changed height
to 800 and width
to 650, as that graph is a bit tall. I also added a <center>
tag to place it in the center of the published version.
Plotly also has a target URL for embedding. In this case, it's https://plot.ly/~etpinard/251.embed. RPubs doesn't seem to like that though. You also might play around with borderwidth
to see if you can turn off the border.
That's all to say: the graphs won't show up in the preview. I believe this is a browser limitation, as RStudio doesn't allow for publishing live web content (yet).
If you're interested and would like some example code, here is the source for a blog post that has embedded Plotly and ggplot2 plots. Hope this helps! Disclosure: I work for Plotly.

Head to the Plotly documentation to see the R Markdown version of this answer. Printing plotly objects in the R console creates an online figure. For example:
p <- plot_ly(economics, x = date, y = uempmed, filename="r-docs/knitr-example")
If you are using knitr/R Markdown with HTML output, printing the plotly
object will now embed the plot in the HTML as an iframe. If you are writing a document with R Markdown, simply printing p
will embed the plot.
You can also set the width and the height of the plot with width and height code chunk parameters. For example: {r, height=800} sets the height.
If you are using Plotly Offline with R Studio, then printing the plotly object in knitr will also include the necessary plotly.js files to draw the graph: the graph is rendered locally inside the document.
To convert the knitr document to a standalone HTML file, use knitr::knit
and markdown::markdownToHTML
. For example:
knitr::knit('plotly-report.Rmd', 'plotly-report.md')
markdown::markdownToHTML('plotly-report.md', 'plotly-report.html')
