I'm trying to use the regexpr function to locate the decimal in a character
string. Regardless of the position of the decimal, the function returns 1.
For example,
> regexpr(".", "Female.Alabama")
[1] 1
attr(,"match.length")
[1] 1
In trying to figure out what was going on here, I tried the below command:
> gsub(".", ",", "Female.Alabama")
[1] ",,,,,,,,,,,,,,"
It looks like R is treating every character in the string as if it were
decimal. I didn't see anything in the help file about "." being some kind
of special character. Any idea why R is treating a decimal this way in
these functions? Any suggestions how to get around this?
Thanks for any suggestions.
