Hello,  
I tried to open a dataframe that was generated in R; the dataframe is opened with libreoffice calc with no errors:

```julia
julia> df = CSV.read("/home/gigiux/Downloads/epiCurve/covidDataFrame.tsv",
           delim='\t', missingstring="NA", decimal='.')

```

What would be the problem?

Try doing it with `header = false` or `datarow = 2` as keyword arguments since the error seems to be stemming from the creation of the header.
