F is an abbreviation of FALSE, in R,e.g.:

> class(F) 
[1] "logical"
> typeof(F)
[1] "logical"
 
(likewise, T is the same as TRUE) If you want to keep it a string (aka 
character), just try adding quotes in Oracle (select '"' || 
some_column || '"' ), and/or use as.character(thing) on the R side. Hope this 
helps,
