Rmd was hit and miss, and polymode was just a mystery to me. More recently, however, my go-to methods for configuring Emacs+ESS were failing indentation was all over the shop, the smart _ stopped working or didn’t work as it had for over a decade, syntax highlighting of R-related files, like. For years this has served me well, though I wouldn’t call myself an Emacs expert not even close! With a bit of help from some R Core coding standards document I got indentation working how I like it, I learned to contort my fingers in weird and wonderful ways to execute a small set of useful shortcuts, and I even committed some of those shortcuts to memory. I’ve done so for nigh on a couple of decades now, ever since I switched full time to running Linux as my daily OS.During that search I came across radian, a neat, attractive, simple console for working with R.Answer (1 of 3): Many will tell you you need an IDE. So, in a fit of pique following one to many reconfiguration sessions of Emacs+ESS, I went in search of some greener grass. Also, fiddling with this stuff just wasn’t fun any more.
![]() Best Text Editor With R Full Time To![]() ![]() Pressing the up cursor ↑ will retrieve the previous set of commands pasted or piped into radian, and repeatedly pressin ↑ will scroll back through the history. Code completion in radianWe also get nice syntax highlighting of R code using the colour schemes from pygments: Syntax highlighting in radian using the monokai themeAnd, if you’re copying & pasting code into the terminal or piping code in from a editor with an embedded terminal (that’s running radian) then you also get rather handy multiline editing. Hit Tab again or press the down cursor and you can scroll through the potential completions. To activate this you start typing, hit Tab and the relevant completions pops up. On Fedora, you configure this alias in your ~/.bashrc file alias r="radian"Having started radian you’ll see something like this radian at start-up running in a bash shell on FedoraRadian starts up with a simple statement of the R version running in radian and the platform (OS) it’s running on so is it just a less-verbose version of the standard R console? The radian prompt hints at the greater capabilities however.Code completion is a nice addition yes, you have some form of code completion in the standard R console but in radian we have a more RStudio or Emacs+ESS-like experience with a drop-down menu for object, function, argument, and filename completion. Mac app to scan folder for picturesThe only issue I’ve noticed is that it is a little slow to print tibbles, and clearly it’s not going to replace my current IDE — that’s not what it is designed for. This is useful for entering the assignment operator <-, which I have bound to Alt + - using options(radian.escape_key_map = list(Where I’ve added spaces around the operator to mimic how the smart underscore works in Emacs+ESS.I’m really liking using radian for my throw-away R sessions that I typically do in a terminal. I’ll probably play with both options and see which I like best after a few more weeks of use.You can also define shortcuts. Setting radian.insert_new_line = FALSE, as I have it on the laptop results in more standard behaviour but it can feel a little cramped. The options I’m currently using on the computer used for the screenshots in this post are: options(radian.auto_indentation = FALSE)But on my laptop I’m currently using # auto match brackets and quotes# auto indentation for new line and curly braces# timeout in seconds to cancel completion if it takes too longOptions(radian.completion_timeout = 0.05)The last option is something I’m not sure about yet as you can see in the screenshots, there’s a new line between the prompts, which makes it super easy to read the R code you’ve entered, but with the font I’m currently using ( Iosevka) things look a bit too spread out. Hitting enter will run the entire chunk of code for you, edits and all: Multiline editing a ggplot call in radianYou can configure aspects of the behaviour of radian via options() in your.
