Martin:
What I suggested was he remove the LazyData entry from the description file
if he was NOT lazy loading data. If someone is lazy loading data, then that
is a different situation, and they obviously need to set the entry.
But clearly Gm has a different problem. He has now tried "LazyData: true",
"LazyData: false", and removing the LazyData entry entirely. And he is
still getting this error:
* installing *source* package 'movecost' ...
** using staged installation
** R
** data
** byte-compile and prepare package for lazy loading
ERROR: lazy loading failed for package 'movecost'
* removing 'd:/RCompile/CRANguest/R-release/lib/movecost'
So changing the description entry isn't helping. Maybe someone else has a
suggestion of what to try next.

Dear David,
where did you get this "idea" that 'LazyData' is not good for R 4.1.0 and
newer ?
R's own {datasets} package *does* use lazyloading, and so do most
(formally) recommended packages, and I think most packages I (co-)maintain,
i.e., around two dozen CRAN packages do use lazyloaded data.
---
*) The `Matrix` package is a big exception with 'Lazyload: No'
because its datasets partly are (S4-) classed objects from the package
itself, and -- as the "WRE" ('Writing R Extensions') manual states --
package datasets must not *need* the package itself when they should be lazy
loaded.
