creating a dummy variable based on a list of elements

ilikesas — Sun, 17 May 2015 02:52:38 GMT

hi,

suppose that I have the folllowing table:

text
The banks and financial companies
The bankers association
First bank of England
financial banking institutions

If either the element "banks" or "financial" is present in an entry, then the new dummy variable =1, else 0.

So the table should be like this:

text	Header 2
The banks and financial companies	1
The bankers association	0
First bank of England	0
financial banking institutions	1

thank you!

thanks Xia, your posts are very helpful, (as well as the posts of the other users)!

I actually tried to do this myself and even experimented with prxmatch, but even the smallest syntax inaccuracy can make the whole code not work (or work in an unintended way ...)

Thanks again!
