Take a look into your library and manually remove the 00LOCK directory (if exists) and you can also delete the "fields" directory therein. Then start a clean R session without attaching/loading/importing fields and try to reinstall it which should work now.

Best wishes,

I used packages 'fields". when I load workspace again, then
do installation again.
I get the following error.  I read R for Windows FAQ (4.8 see below), but I
still can't
figure it out. Does anyone can help me out?

Thanks,

You may not be able to update a package which is in use: Windows `locks' the
package's DLL when it is loaded. So use update.packages() (or the menu
equivalent) in a new session.

If you put library(foo) in your .Rprofile you will need to start R with
--vanilla to be able to update package foo. If you set R_DEFAULT_PACKAGES to
include foo, you will need to unset it temporarily.

It has been reported that some other software has interfered with the
installation process by preventing the renaming of temporary files, *Google
Desktop* being a known example.
