Dear R users,
apologies for this quite simple question. I've tried serverall
approaches, however, could not generate the desired result.
I have a large data frame, which has several cathegories encoded as
character strings, for example.
Name, income, gender, ...
... "from 1000$ to 2000$" ...
... "from 2000$ to 3000$" ...
... "more than 3000$" ...
... "from 1000$ to 2000$" ...
... "from 1000$ to 2000$" ...
How can I transform this column into numeric values for the categories,
for example in somethins like this:
... 1000 ...
... 2000 ...
... 3000 ...
... 1000 ...
... 1000 ...
