Hi,
I tried to install from four different mirrors. The result is the

dnt understand what the following error means.
/usr/lib/R/library/ncdf/libs/ncdf.so: cannot restore segment prot
after
reloc: Permission denied
Error in library(ncdf) : .First.lib failed for 'ncdf'
I even tried to change the permission of ncdf.so but still i am not
able to
load the library.
Nothing to do with the download. I think SElinux is getting in your
way
(so your unstated system could be RedHat Enterprise Linux?).
Contact your sysadm or google for the error message.
(One of the hits suggests that you might need to run
chcon -t texrel_shlib_t ncdf.so
but, well, no warranties...)
The OP did indicate that F10 was the platform:

so I would agree here that SELinux is almost certainly the culprit as
it does control relocation.
If you have the SE Troubleshoot daemon running, you should get a
yellow star/badge symbol on one of your desktop dock panels.
Typically, if you click on this, it will bring up a dialog window that
will have some specific suggestions for resolving the problem. You can
see some visual examples here:
