Errors with readtable

[nalimilan]

I'm getting an error when reading a CSV file:

> df = readtable("somefile.csv")
DataFrame with 4596 rows, 7 columns
Columns:

WARNING: max(x) is deprecated, use maximum(x) instead.
 in depwarn at deprecated.jl:29
 in max at deprecated.jl:19

Evaluation succeeded, but an error occurred while showing value of type DataFrame:
ERROR: max: ordering is not well-defined for arrays
 in maximum at reduce.jl:33
 in max at deprecated.jl:21

The first error (not the warning) can be reproduced with these contents:

K1,ROW_LABEL,age6,diplo,csp,local,revenu
c'est tout; l'espace en général,4   ,34-45a,Sup,ajf&dkf,THG,4b20MG

Also, only with the full file, if I try to change the separator to ';' (which is wrong for this file), I get a cryptic error:

> df = readtable("somefile.csv", separator=';')
ERROR: BoundsError()

This is because of JuliaLang/julia#4235. Unfortunately I did not understand the rationale behind the renaming, so I won't change code I do not understand, but probably the only required action is to change max in https://github.com/JuliaStats/DataFrames.jl/blob/master/src/dataframe.jl#L903 to maximum.

This seems to have been fixed by some of Dahua's patch. Can someone confirm that this occurs on their copy of master? I don't see any errors in the test suite.

[nalimilan]

Yeah, it works with master thanks to commit bd3e333, sorry for the noise.

No worries. Just wanted to figure out what was going on. Always really interested to see CSV files that we legitimately can't read (but should be able to).
