object_usage_linter (and probably others) use namespace of installed package #91
Description
Local changes to the NAMESPACE file are reflected only after package is installed. To reproduce:
pkgname="lintr.namespace.test"
rm -rf $pkgname
Rscript -e "devtools::create('$pkgname')"
Rscript -e "devtools::install('$pkgname')"
echo "a <- function() {" > $pkgname/R/a.R
echo " llply" >> $pkgname/R/a.R
echo "}" >> $pkgname/R/a.R
echo "importFrom(plyr,llply)" > $pkgname/NAMESPACE
# Uncomment line below to fix error
#Rscript -e "devtools::install('$pkgname')"
Rscript -e "lintr::lint_package('$pkgname')"An equivalent R script didn't exhibit the same error, so this one might be difficult to test automatically.
