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

问题 After having set the path for the default working directory as well as my first (and only) project within RStudio options I wonder why RStudio keeps creating an empty folder named "R" within my "/home" directory every time it is started. Is there any file I could delete/edit (eventually create) to stop this annoying behaviour and if so, where is it located ? System: Linux Mint v. 19.3 Software: RStudio v. 1.3.959 / R version 3.4.4 Thanks in advance for any hints. 回答1: Yes, you can prevent the

问题 What is the command or keyboard shortcut equivalent to pressing the little broom button in the History window of RStudio which clears out the entire history buffer in the current session? Note that I don't mean Ctrl + L which clears the command window, I mean clearing history which is accessed by pressing the up-arrow. 回答1: Function based on Carl Witthoft's helpful comment which clears the history (assumes you can write to the working directory): clearhistory <- function() { write("", file="

问题 I regularly code in R, and I just realized how much of a pain it is for me to move my hand down to the arrow keys and then back to they letters on the keyboard. In Rstudio, I have to do this regularly because the studio completes certain synax automatically, (like parentheses and quotation marks) and then I have to press the arrow key to move out of the parentheses (or quotation marks), this then removed any possible advantage from having R complete the syntax for me. This is extra costly for

问题 I am trying to create a dummy variable for R. The thing is there are many categorical variables under my dataset of restaurants 'type'. Among them, I want Vegan restaurants to have value 1 and the rest to be 0. So when I run summary of the regression, I get the intercept, and b1 as reviews_number and b2 as vegan restaurants. For example, a non-vegan restaurant would be y=b0+b1(reviews_number) and a vegan restaurant will be y=b0+b1(reviews_number)+b2(Vegan). The hint is to use ifelse()command,

问题 Possible duplicate question, but I don't know the startup process of RStudio to tell if the problems are the same. I'm using RStudio Desktop v0.99.442 on Linux. From the console inside RStudio, I run system("echo $PATH") /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games However, my real $PATH (which I see when I echo $PATH from the console) has a lot of other programs on it that I'd like to be able to call using system() from R. For example, in my
