Hi,
It probably depends on where you are publishing and what you are publishing. As @technocrat points out "often publications have exacting requirements".
" Until now, I am putting my R results manually in the word document'.
You should consider looking into using Rmarkdown or the new Quarto writing systems that are designed to integrate well with R
Tables with Rmarkdown gives a bit of genoral information on using tables information. The stargazer package may be useful and the qwraps2 package looks like it might be handy.
If you have the pleasure (horror?) of using APA style there are some dedicated packages such as apaTables or papaja. I believe that {papaja} is only usable in Rmarkdown or Quarto which will give Word, PDF & HTML output.
Both of the APA style packages probably will provide tables that are fine in other publications. They are just intended to meet the APA Manual's rather exacting demands.
