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")
  You probably want backslashes to indicate that "." should not 
be treated as a metacharacter; it should be taken literally.

> regexpr("\\.", "Female.Alabama")
[1] 7
attr(,"match.length")
[1] 1
hope this helps,
