The output of `glimpse()` is too wide in RStudio Visual Editor mode

[GegznaV]

In RStudio Visual Markdown mode, the output of glimpse() is distorted (the summary of one column does not fit into a single line)

Steps to reproduce the issue:

1. select a data frame with a big enough number of rows;
2. apply glimpse() on the data frame.

Current output of pillar::glimpse(iris):

Expected output (the output in console):

If the editor's pane is made even wider, the issue gets even worse:

Thanks. The width is controlled by getOption("width") , IIRC. Can you check the value of this option in the visual markdown editor? Can you work around by setting the option to a smaller value?

[GegznaV]

Yes, sure. In the following circumstances, the width is 133:

So I'm not sure if this is an issue with Visual Editor, which provides the wrong value of output width, or of glimpse(), which does not correct it appropriately. What do you think?

It seems that the glimpse() output is at most 132 characters per line?

In the IDE, the "width" option is changed when you resize the console tab. Does this have an effect on the visual editor?

[GegznaV]

Yes, the value changes. But it seems that getOption("width") shows the total width of the editor (or console) window and not the width of the Visual Editor output area. The same width is printed when I run code in the Visual editor and the console (I expect different):

One more test. I measured the number of characters that fit into a single line of output:

Can you please take this to https://github.com/rstudio/rstudio then? This will also affect other packages that use the "width" option. This might be a known issue, haven't looked.
