Hi, I am trying to build an R package so reading the manual on CRAN. I could figure out that using imports to load functions in your namespace would be the best bet to use in the Description file. After adding to the description file, I also added it to the namespace file. I added importFrom to the namespace file with the functions required. Now when I run R CMD check on my package, I get an ERROR as Namespace dependencies not required : 'ggplot2' Further imformation : Even if i add the package to the Depends in the description file, they are not getting loaded. Please help with this. Mayank Bansal| +91 9901729939 | www.mu-sigma.com | ________________________________ This email message may contain proprietary, private and confidential information.
