My first thought on this was to apply the regexp "^([0-9]*)(.*)$" and
getting the two parts out. But I dont see a way to get both matches in
parentheses out in one go.
In Python you just do:
>>> re.findall('^([0-9]*)(.*)$',"123abc")
[('123', 'abc')]
>>> re.findall('^([0-9]*)(.*)$',"1e12")
[('1', 'e12')]
In R you can get the groups and go gsub on them:
> r="^([0-9]*)(.*)$"
> gsub(r,"\\1","123abc")
[1] "123"
But I dont see a way of getting the two values out except as part of
one string in gsub - which is right back where you started - or doing
gsub twice.
