I get this message when I try doing an analysis using Julia 1.1:

```julia
ERROR: UndefVarError: readdlm not defined

```

I tried `using DelimitedFiles` as suggested elsewhere ([error in read data in JULIA v1.0](https://discourse.julialang.org/t/error-in-read-data-in-julia-v1-0/13308)) but received the same error message. Any ideas on how to solve this issue?

This should work - please post your version info.

In the official julia 1.1 build I have:

I’m getting a similar error, I am `using DelimitedFiles` but when I try to use `writelm` I get the error ` UndefVarError: writelm not defined`
