[Roxygen-devel] [roxygen2] error sourcing the R files (probably environment issue)

[Renaud Gaujoux]

Forgot the traceback:

 > traceback()
12: eval(expr, envir, enclos)
11: eval(assignee, env)
10: parser(call, env)
9: FUN(X[[1L]], ...)
8: lapply(src_refs, parse.srcref, env = env)
7: force(code)
6: parse_cache$compute(c(env_hash, readLines(file, warn = FALSE)),
        {
            src_refs <- attributes(parse(srcfile$filename, srcfile = 
srcfile))$srcref
            pre_refs <- prerefs(srcfile, src_refs)
            if (length(src_refs) == 0)
                return(list())
            src_parsed <- lapply(src_refs, parse.srcref, env = env)
            pre_parsed <- lapply(pre_refs, parse.preref)
            stopifnot(length(src_parsed) == length(pre_parsed))
            mapply(c, src_parsed, pre_parsed, SIMPLIFY = FALSE)
        })
5: FUN("/home/renaud/Documents/tmp/test/R/fun.R"[[1L]],
        ...)
4: lapply(paths, parse.file, env = env, env_hash = env_hash)
3: unlist(lapply(paths, parse.file, env = env, env_hash = env_hash),
        recursive = FALSE)
2: parse.files(r_files)
1: roxygenise(".")
