I am new to Orange and it seems very useful for conducting exploratory data analysis.
One question I have is - can we use a widget to modify some values in the dataset?
For example, several numerical columns have some values of 0 which does not make sense and should be a "missing data". I do not want to ignore the line as some other column data are important. Also not all 0 should be replaced with "missing data" as for some column, a 0 is a valid data. Can we do that with a widget? I could not figure it.
Thank you for the help!
