[R-pkg-devel] Dependency needs to be loaded manually even its specified in the package

Hi Dirk,

Thanks for your comment. Maybe I haven't been enough clear. The package 
declares all the necessary dependencies correctly following the 
guidelines you provide. I am only able to detect the problem by running 
an example:

This works:

      library(CSTools)
  ??? library(qmap)
      exp <- lonlat_data$exp
     ?obs <- lonlat_data$obs
     ?res <- CST_QuantileMapping(exp, obs)

This fails:
      library(CSTools)
      exp <- lonlat_data$exp
     ?obs <- lonlat_data$obs
     ?res <- CST_QuantileMapping(exp, obs)

The DESCRIPTION sets:
Imports:
qmap,

The function sets:
|#'@import qmap|  

The NAMESPACE sets:
|import(qmap) I guess I am missing something to check but I don't know 
what. Thanks for your help. N?ria |

You never use library() in a package. Rather, you declare dependency
relationsships via DESCRIPTION (and likely NAMESPACE). See "Writing R
Extensions" for all the details.
