library - R CMD build mypkg.





Hi,

I am getting an error when I am trying to build a library in R for windows
. I am using R 2.7.0 in windows. I am following the instructions listed in
the R Help for package creation.

require(stats)
## two functions and two "data sets" :
f <- function(x,y) x+y
g <- function(x,y) x-y
d <- data.frame(a=1, b=2)
e <- rnorm(1000)

package.skeleton(list=c("f","g","d","e"),
name="mypkg")


Then in the command prompt I executed the following command:

      R CMD build mypkg

I am getting the following error :

* checking for file 'mypkg/DESCRIPTION' ... OK
* preparing 'mypkg':
* checking DESCRIPTION meta-information ... ERROR
During startup - Warning messages:
1: In library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return
= TRUE,  :
' there is no package called 'NULL
 in options("defaultPackages") was not found

What is it that I am not doing right ?

Thanks,
Ajay.
