I'm trying to use the RStudio Visual Editor more for Quarto notebooks.
I really like it, but I there's an issue that makes it unusable: when I print a data.frame
from a chunk, it gets printed in a very narrow rectangle that does not scale up (as it would with the normal source editor).
This makes it unusable because often I can't see the full variable names or the full values.
I tried looking at the options (Global Options > R Markdown > Visual) but I can't find anything that changes this: Editor content width only changes the width of the text and code, not the chunk output.
Coercing a data.frame to tibble also doesn't fix this.
I'm using RStudio 2022.07.2 Build 576.
Alright I know I answered this question before. I can't find that question or my answer in Stack Overflow, but I found the script I used to create & test the answer. I tested it because I think it was a few years ago. Everything seems to work.
This isn't a permanent solution. It will persist until you restart RStudio.
Step 1: Right-click anywhere in RStudio and select 'Inspect Element' from the dropdown to open developer tools. If you weren't aware, it's just like a browser that way.
Step 2: You need to use the console. Whether you use the console drawer (three dots) or the console tab (top of the inspector window, second from the left).
The first JS function
At the cursor, you'll paste two javascript functions. I store these in an RMD, within a JS chunk. They won't do anything when you knit.
allOf = document.querySelectorAll('[data-ordinal]'); //find them all
if (allOf==undefined || allOf==null) {
allOf = document.querySelector('[data-ordinal]'); // if there is only one
}
sAdd = "max-width: none;" // create style to add
try{
for(i = 0, n = allOf.length; i < n; i++){ //loop through them all
styler = allOf[i].getAttribute("style");
if (styler==undefined || styler==null) { // if there are no HTML styles set
styler = "";
console.log("No style attributes found for ", i);
}
if (styler!="width: 100%; max-width: 800px;") {// if this isn't a chunk output as expected
continue;
console.log("Attributes not changed for ", i);
}
allOf[i].setAttribute("style",styler+sAdd);
console.log("Attributes set for ", i);
}} catch(error) {
console.error(error);
}
The second JS function
allMore = document.querySelectorAll('.ace_lineWidgetContainer > div'); // first child of class
if (allMore==undefined || allMore==null) {
allMore = document.querySelector('.ace_lineWidgetContainer > div'); // if there is only one
}
sAdd2 = "overflow: visible;" // create style to add
try{
for(j = 0, m = allMore.length; j < m; j++){ //loop through them all
styler2 = allMore[j].getAttribute("style");
if (styler2==undefined || styler2==null) { // if there are no HTML styles set
styler2 = "";
console.log("No styles were found for ", j)
}
allMore[j].setAttribute("style",styler2+sAdd2); // append new styles
allMore[j].style.height = null; // remove the height style
console.log("Attributes set for ", j);
}} catch(error) {
console.error(error);
}
