hi guys:
i export csv files from an url by using urlwrite and readtable commands. the resulting table is (or should be) composed of numbers, somehow some table cells has the value '-'. Because of this, the whole column containing that string '-' become into string values, like this:
column1 column2
------- -------
'12' 34
'10' 12
'-' 20
'1.1' 13.1
'34.9' 66
is there a way to avoid it? i mean, the whole table as numbers...
thanks

Is it possible that the original data contained "- 20" with a space between the "-" and the "20" ?
