Not able to install package

[michielvandijk]

Hi,

As I want to download several WorldPop covariates, I was trying to install wpgpDownloadR but encounter and error. When I install the package using devtools, I get the error below, which seems to indicate a conflict with RCurl. I also would like to mention that in the Github documentation often reference is made to "wpgpCovariates", which seems to be the predecessor of the package. The installation of this package goes fine but its use requires a username and password, which I do not have. I tried using username = "ftpUsername" and password = "ftpPassword" but I assume that these are examples and one needs a real password (is still active). Any advice is much appreciated.

Installing package into 'C:/R/library/4.0.2'
(as 'lib' is unspecified)

I found the solution to my problem here: r-lib/remotes#403 It has to do with the removes package which actually seems to stop installation in case of warnings, such as having a (slightly) older package installed (in my case RCurl 4.0.2 instead of 4.0.3). This can be fixed by setting: Sys.setenv("R_REMOTES_NO_ERRORS_FROM_WARNINGS" = "true") before using install_github.
