csv file reading header=TRUE default

[ivo welch]

I am a complete julia novice, so I may simply not understand the following.  when I type

julia> d=readcsv("myfile.csv")
julia> typeof(d)

Array{Any,2}

I think this shows that it interprets the header as data, and sets the columns to be of type "any".  alas https://dataframesjl.readthedocs.org/en/latest/io.html#advanced-options-for-reading-csv-files states that `header::Bool – Use the information from the file’s header line to determine column names. Defaults to true.`  but it only works if I force it to true:

julia> d=readcsv("myfile.csv", header=true)
julia> typeof(d)

Tuple{Array{Float64,2},Array{AbstractString,2}}  

 

seems to interpret the header as variable names.

is header=true the default on readcsv, is the docs wrong, or am I doing something wrong?

The link below points to "readtables" but you are using "readcsv" as the command.

I see.  thank you.  it was a little confusing.  it was right under the header

Indeed, but its in the dataframes package documentation, its all about "readtables", and nowhere in dataframes documentation is "readcsv" mentioned.
