Betreff: st: string functions
Hello,
I have a basic question on using string functions to do the following:
I have variable labels that have various units in brackets: (cm) (cm sq)
etc. and I want to remove these from the label.
How can I search a string for the portion between brackets (including
the brackets) and replace this with a blank?
For example if my variable area has the following label: "area (cm sq)
of ..."
I want to replace the label with : "area of ..."
I have many variables so I want to automate this rather than having to
type in individual labels...
I use stata v10
Many thanks!
