Numbers in a string

Hi Felipe,

gsub("[^0123456789]", "", "AB15E9SDF654VKBN?dvb.65")
results in "15965465".
Would that be what you are looking for?

If your OS is Linux, you might want to look at sed or gawk. They are very
good and efficient for such tasks.
You need it once or as a part of program? 
Some samples would be helpful...

Betreff: [R] Numbers in a string

Hello, I have stings which have all sort of characters (numbers, letters,
punctuation marks, etc) I would like to stay only with the numbers in
them,
does somebody know how to do this?

Thank you

Felipe Parra
