Details:

dataframe 1.1.0

Consider following file "afile":

string1;int1;string2;string3
a;1;hello;
b;2;world;huhu


if read there is an error:

d=dataframe("afile", "sep", ";");
Something went wrong while converting colum 4
Error was: cell2mat: wrong type elements or mixed cells, structs, and
matrices
stopped in /home/andy/octave/dataframe-1.1.0/@dataframe/private/df_matassign.m
at line 357
357:           keyboard;


if the int colum is removed so that "afile" reads

string1;string2;string3
a;hello;
b;world;huhu


the first column isn't read:

> dataframe("afile", "sep", ";")
ans = dataframe with 1 rows and 3 columns
Src: afile                               
_1 string1 string2 string3               
Nr    char    char    char               
 1       b   world    huhu
