When I startup my R (in RStudio IDE), I receive the warning:

Warning: namespace ‘slidify’ is not available and has been replaced by .GlobalEnv when processing object ‘.SLIDIFY_ENV’

Yesterday I uninstalled slidify (and slidifyLibraries) as this package interfered with regular use or .Rmd (Rmarkdown) files (when I pushet knit button in RStudio, all the .Rmd files were rendered as slidify slides, despite the fact that they had to be rendered as usual Rmarkdown files).

Question: How can I get rid of the warning message at the startup?

Warning: namespace ‘slidify’ is not available and has been replaced by .GlobalEnv when processing object ‘.SLIDIFY_ENV’

That is telling you there's an object called .SLIDIFY_ENV in your R workspace at startup which is associated with the now-missing slidify namespace. Remove it (rm(.SLIDIFY_ENV) should work), save your workspace. Restart R and it shouldn't re-occur.
