问题 I'm working on a shiny app and I'm running into difficulty with observeEvent() function when creating a complex expression of multiple inputs that all derive from selectInput() . My issue is some of the expressions within the observeEvent() function are triggered at startup, causing the event to prematurely execute (i.e. my actionButton() is disabled at startup, as it should be, but becomes enabled when at least one of the inputs are selected when ideally I would want it to become enabled

问题 Say I have a simple rmarkdown document called test.Rmd --- output: pdf_document --- This code tries to save output to a file called 'example.txt' ```{r} sink(file='example.txt') sink.number() library(MASS) summary(cars) sink() sink.number() ``` If I run this in RStudio (using the knit PDF button) then I get lots of output but I believe the most important is the following (I can include the other output on request) processing file: test.Rmd "C:/Program Files/RStudio/bin/pandoc/pandoc" +RTS

问题 I can't find a way to insert an inline image on a markdown document I'm producing with RStudio. Seems like the RmarkDown Style Cheat sheet (https://www.rstudio.com/wp-content/uploads/2016/03/rmarkdown-cheatsheet-2.0.pdf) does not mention such feature. Is this currently possible? Here's an example using html for a svg image: link: http://www.herongyang.com/HTML/HTML5-Add-Inline-SVG-Image-HTML5-Documents.html 回答1: Markdown syntax allows inline images: foo  bar 回答2: Could also use
