[R] sqldf not joining all the fields

[Gabor Grothendieck]

Yes, its not clear what data was used.  Please provide a single email
that contains code that can be copied from R and pasted into another
session that will reproduce the problem.

x_data <- ...dput output goes here...
y_data <- dput output goes here ...
library(sqldf)
... rest of code ...

or else:

x_data <- read.table("http://...", ...)
y_data <- read.table("http://...". ...)
library(sqldf)
... rest of code ...
