question/bug: Emacs hangs when using ess-view-data-print

[nettoyoussef]

Hi, thanks for the effort put in this package.

I am not sure why, but Emacs+ESS just hangs when I use ess-view-data-print on a dataset (such as the mtcars in the example). Maybe I am missing some R dependency? Which are the packages that I should have installed to use ess-view-data?

My installation is just a vanilla one with straight:

(use-package ess-view-data 
 :straight t
 :defer t
)

What is the version of your emacs and ess?

R library:

• dplyr for ess-view-data-backend-list is dplyr by default.

Optional:

• knitr for ess-view-data--kable-format
• skimr for ess-view-data-skimr
• tidyr for ess-view-data-wide2long and ess-view-data-long2wide

If you switch to other ess-view-data-backend-list, DT or data.table is needed.

By the way, csv-mode for Emacs is recommended for headline, but if you don't have it, it will not make emacs hang.

Hi, thanks for the fast response.

I am using Emacs 28.0.50 and ESS commit cb75588d972b97e597c42108b3c83c2f67947cac (I use straight to manage packages).

I think that the problem may be caused by a non-closed quote or by missing some block character such as ). After it hangs, if I cancel everything and try to run any command, e.g., install.packages, it returns this error message:

Error: unexpected symbol in:
"mp <- options("width", "tibble.width", "crayon.enabled");options(tibble.width = Inf, width = 5000, crayon.enabled = FALSE);print(`datajndnxz`[(0*200 + 1) : min((0 + 1)*200, nrow(`datajndnxz`))
}install.packages"

It seems part of the "local({....})\n". However I didn't find “)\n”.

would you please (setq ess-verbose t), and then find out what is say in buffer *ESS*?

[nettoyoussef]

Hi, sorry for the delay.

The ESS buffer reports the following logs:

Trying to execute the R commands that appear above works flawlessly in the prompt so I am not sure where is the source of the bug.

May I ask whether the issue is still open?
