Hello,
Here below I have a column called EMAIL
Of all the emails we wanted to check how many times gmail was wrongly entered....
Since GMAIL starts with the letter "G" we can take all the words starting with letter G after @ in the email adress??????
HAVE:
apple@gmail.com
buffalo@gmail.com
cat@gunail.com
dog@GMAI.COM
elephant@gmail.con
goat@yahoo.com
horse@hotmail.com
kangaroo@gnail.com
horse@gmi.com
WANT:
gmail.com 2
gunail.com 1
GMAI.COM 1
gmail.con 1
gnail.com 1
gmi.com 1
I will suggest that limiting your search to @g is insufficient. You may well have enteries like Johh@jmail.com or John@fmail.com or ...
I might be tempted to do something like:
data have;
length email $40.;
input email;
isp =upcase(scan(email,2,"@"));
distance = complev('gmail.com',isp,'i');
datalines;
apple@gmail.com
buffalo@gmail.com
cat@gunail.com
dog@GMAI.COM
elephant@gmail.con
goat@yahoo.com
horse@hotmail.com
kangaroo@gnail.com
horse@gmi.com
john@tmail.com
john@jmail.com
;
proc tabulate data=have;
class distance isp;
table distance*isp,n;
run;
The "distance" value when small means the spelling is "close" to Gmail.com.
Note that I did add in couple of other possibly typos.
