Cran Error in Suggests related to "lfe"

[s3alfisc]

"Please see the problems shown on
https://cran.r-project.org/web/checks/check_results_fwildclusterboot.html.

Please correct before 2021-08-08 to safely retain your package on CRAN.

Packages in Suggests should be used conditionally: see 'Writing R Extensions'.
This needs to be corrected even if the missing package(s) become available."
From "writing R extensions":

"1.1.3.1 Suggested packages

Note that someone wanting to run the examples/tests/vignettes may not have a suggested package available (and it may not even be possible to install it for that platform). The recommendation used to be to make their use conditional via if(require("pkgname")): this is OK if that conditioning is done in examples/tests/vignettes, although using if(requireNamespace("pkgname")) is preferred, if possible. "

[s3alfisc]

Added if(requireNamespace("pkgname")) statements for suggested packages in the vignettes, examples and tests.

Note that unit tests will now only execute on CRAN if both fixest and lfe can be installed on the specific OS.

Currently, package installation fails on ubuntu-20.04 (devel) because the installation of the suggested "lfe" package fails (based on commit c84fffe).

See also https://cran.r-project.org/web/checks/check_results_lfe.html.

Probably related to this bug in "lfe": sgaure/lfe#49.

lfe 2.8-7 was just accepted on CRAN, this should fix the issue!?

Hi Mathieu, thanks for letting me know! This indeed fixes this issue :)
All bugs mentioned above are now adressed with version 0.3.6 and commit bf3d289 & fwildclusterboot 0.3.6 is on CRAN!
