Unload strict library in R

unload_strict.md

The strict R package is a great tool for helping to build robust R code. However, there are times when it doesn't place nicely with certain packages.

For example, the GenomicRanges packages defines functions with the same name as base functions (e.g. gsub) and then calls them without specifying the namespace, which results in strict rightly complaining about a conflict.

Unfortunately, you cannot just detach the strict package. These commands will detach strict's functionality (or silently do nothing if it isn't loaded):

if ("strict_conflicts" %in% search()) detach("strict_conflicts")
if ("strict_shims" %in% search()) detach("strict_shims")
if ("strict" %in% loadedNamespaces()) unloadNamespace("strict")
