问题 I searched a lot for this but couldn't find any package or a guide on how to view a ".ppt" file on a webpage using react.js. I'm allowing the user to upload a ".ppt" file, and I want him to be able to view that "Powerpoint" file in a web page, is that even possible? I tried the following but it didn't work ... <iframe src={`https://view.officeapps.live.com/op/embed.aspx?src=[${linkToPPTFile}]`} width="100%" height="600px" frameBorder="0" ></iframe> Any help will be appreciated. 回答1: It

问题 I'm trying to build a plot incrementally on one slide using Rmarkdown to create an ioslides (HTML) presentation. I've tried using {.build} but to no avail, and it seems there is no documentation on this in the Rmarkdown community. Does anyone know how to write this code in R? Here is a MWE where I try to build a plot in three steps, from a blank plot to a scatterplot to a lineplot, all in one slide where the plots unfold by clicking forward one at a time: --- title: "Untitled" author: "User"

I came across this question about presentation materials with a very good answer from Pascal. But I really need a demo project to actually show Maven in action, some sort of toy project, simple but complete enough to illustrate the
