I have been informed by CRAN administrators that the development version of R issues warnings for my package(s). Some are easy to mend (such as Internet links not working anymore), but this one I don't know how to avoid:
Error in if (class(e) == "try-error") { : the condition has length > 1 I understand that `class` can return more than one value. But what would be the appropriate way to catch an error in a construct like this: e <- try(b <- solve(a), silent=TRUE) if (class(e) == "try-error") { # ... do something } Should I instead compare the class with "matrix" or "array" (or both)?. That is, in each case check with a correct result class instead of an error?
