how_to_create_a_package?

hello sir

myself Jyoti Sharma,  and i am working as preoject fellow in IGIB Delhi.
I need your help to know how to create a package as well as how to
post that package to the CRAN mirror, for public use. i have used
package.skeleton() command but its not working properly.
So, please suggest me the right way asap.
i'll be very thankful to you.

Hi Jyoti,
Creating packages is not a trivial task. The only ASAP solution that I 
could suggest is to read the first and third sections in "Creating 
packages" ("Package structure" and "Checking and building packages") in 
the "Writing R Extensions" document that comes with R. To see this, invoke:

help.start()

in an R session and it should be the second link down on the left of the 
page that appears.
