Error: object 'M' not found using Bibliometrix

[hernanmr95]

Hi everyone! I just started using R so I dont know much. I need help:

I've been trying to upload a .bib file obtained from Scopus, into biblioshiny(). Once I press start, this is what I get in R console:

Warning: Error in ..stacktraceon..: object 'M' not found
104: isolate
103: exprFunc [/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.6/bibliometrix/biblioshiny/server.R#63]
102: widgetFunc
101: func
88: origRenderFunc
87: renderFunc
83: origRenderFunc
82: output$contents
2: runApp
1: biblioshiny

Does someone know what can I do? Am I lacking any package? The .bib file is OK, I tried it on a professors computer.

Thank you very much.

Hi, and welcome.

Could you post this as a reproducible example, called a reprex, please. That makes it a lot easier to troubleshoot. Here's an example based on the vignette

Hi technocrat. Thanks for answering. I've been trying to use reprex in my post, as you demanded, but I'm also having problems with this hahaha. I keep recieving the line:

No input provided and clipboard is not available

and also:

Error: Clipboard on X11 requires 'xclip' (recommended) or 'xsel'.

Im using Windows and I just followed instructions. Whats xclip and how can I get it?
Sorry about being so newbie hahah I will learn,

thanks a lot

[andresrcs]

Are you using RStudio Server or RStudio Cloud?, if so, then you would not be able to access to the clipboard, a walk-around could be to select the code you want to reprex and then run reprex::reprex_selection() in the console.

[hernanmr95]

Hi. I've been using RStudio Cloud so far.
How do I run code keeping something selected?

Thank you for using your time for helping me, I really appreciate

[andresrcs]

type the code you want to reprex on the "source" pane, select it, and then run reprex::reprex_selection() on the "console" pane.

[hernanmr95]

Hahaha sorry andresrcs, more trouble:

reprex::reprex_selection()
Removing leading prompts from reprex source.
Rendering reprex...
Error: callr subprocess failed: :20:11: unexpected symbol

Sorry if I can not send you a reprex for asking help, I dont want to waste your time
