I'm trying to build a pair of (S3) methods, a "formula" method and a
"default" method. The methods have a "data" argument. If the variables
in question cannot be found in "data" then they should be sought in
the global environment.
My problem is that the generic dispatches on its first argumen
Never use stringsAsFactors on uncleaned data. For one thing you give a factor
to as.Date and it tries to make sense of the integer representation, not the

Hello,
I'm assuming you're reading from an "*.xlsx" file. I'm not sure which

In R environment, they are read as

Hello all,
We have just released the R package 'fedmatch' to CRAN. Following is a
brief description and some links for more information:
With an ever-expanding set of financial data providers, each covering many
of the same firms and entities, matching data sets that do not share common
identifiers
Thanks Greg!

Richard,
The data are important because they show what's happened in that period of
