character position

Try this:

library(gsubfn)
strapply("There are 23 species", "[0-9]+", as.numeric)[[1]]

The gsubfn home pae is at:

Hi,

I'm not being able to capture a position of a 'string' in a character
string.

In this example: 'There are 20 species in this grid'

I would like to capture the string (number) after 'are' and before
'species'. Consider they do not change. I wouldn't like to use substr
because stop position may change.

Thanks

Paulo
