I am trying to install lubridate but I have always the same error message. Looking around it looks related to the fact that it has a function date() which already exist also as base::date(). But during the test of the package it calls date() and therefore the error.

Here the details:
https://stackoverflow.com/questions/45959714/r-lubridate-package-installation-error-in-as-posixlt

It looks like I am the only one to have this problem. I tried to install also an old version of R, to add or remove other packages but I have always the same error...
Maybe someone here can help?

@hylaarborea, this may help you. Just solved a similar problem.

business-science/tidyquant#62

Look at the very bottom of this issue for the section on an .Rprofile script. If that .Rprofile script has a .Last function defined that calls date() then it will crash the installation of lubridate.

Thanks @DavisVaughan
it was just because the line
cat(paste(date(),"\nAdios\n"))
in the file:
~/.Rprofile

@DavisVaughan @hylaarborea It may be worth noting that you can indeed edit your .Rprofile from this:
https://csgillespie.github.io/efficientR/3-3-r-startup.html#rprofile
So maybe a simple purrr script that iterates over the items in your .Rprofile, and if it detects that the .Last function is there, just delete it/remove that line? I would think this is a bad practice, but good to know it's possible to develop a workaround to remove the line.

This issue was caused by lubridate. We were not handling missing argument to date. Sorry for the trouble. Now fixed in master.
