I've got a collection of functions I use that I combine in a local R-package. This works since years. Some of the functions did rely on the packages rgdal
, sp
, and maptools
that are close to their end of life. I managed to edit the function that they use the packages sf
and terra
instead. However, if I try to build the package using R-Studio
and RTools43
I get the error:
> Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()),
> versionCheck = vI[[j]]) :
> there is no package called 'maptools'
I searched all files in the directory but cannot find any file that relies on maptools
. Unfortunately, the only solutions I find suggest to install the missing package, which I don`t want to do, because of the coming EOL status.
In the description file I import the following packages:
IMPORTS:
xts,
magrittr,
R.utils,
parallel,
pbapply,
terra,
tools,
data.table,
hydroGOF,
sf,
plyr,
raster,
dygraphs,
htmltools
I know that this is no reproducible example, but I'm not able to give one.
Thanks for any ideas.
