Hi,

The new “missing” type introduced in DataFrames is a source of many errors in all the Julia programs I have made previously and I would like to find a way to remove this missing type.

For example the competerank() function from package MultipleTesting is not compatible with missing type.

the command

`r = competerank(pv)`

now gives and error :

MethodError: no method matching competerank(::Array{Union{Float64, Missings.Missing},1})

I tried to replace it by :

`r = competerank(skipmissing(pv))`

or

```
pv = convert(Array,pv)
r = competerank(pv)
```

without success

Thank you for your help !
