PM Subject: Error in building
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.
