I’m having difficulties getting a basic CSV file to read. I can read a file without keyword options:
acs = CSV.read("file.csv", limit=10);
but adding keyword options, like
acs = CSV.read("file.csv"; null="NA");
results in the following error:
MethodError: no method matching CSV.File(::CSV.Header{false,Parsers.Options{false,false,true,false,Missing,UInt8,Nothing},Array{UInt8,1}}; debug=false, typemap=Dict{Type,Type}(), null="NA")
Closest candidates are:
CSV.File(::CSV.Header; startingbyteposition, endingbyteposition, limit, threaded, typemap, tasks, debug) at /Users/madeleine/.julia/packages/CSV/MKemC/src/file.jl:220 got unsupported keyword argument "null"
