I am regularly running into a problem where I can't seem to figure out how
maintain correct data order when selecting data out of a dataframe. The
below code shows an example of trying to pull data from a dataframe using
ordered zip codes. My problem is returning the pulled data in the correct
or
ils on the web site.

I have created an S4 object type for conducting fire department data
analysis. The object includes validity check that ensures certain fields
are present and that duplicate records don't exist for certain combinations
of columns (e.g. no duplicate incident number / incident data / unit ID
ensures
addresses)

trying to switch out addresses that have double directions, such as the
following example:
a = "S S Main St & Interstate 95"
a = gsub(pattern="S S ", replacement="S ", a)
the problem is that I don't want to affect instances where this might be
a correct address such as the following:
"3421
and up to 20
different numbers for each unit type. Having an automated way of ordering
these units would be a huge help. Thanks in advance for any help you can
provide.

I am merging two dataframes using a relational key (incident number and
incident year), but not all the records match up. I want to be able to
review only the records that cannot be merged for each individual dataframe
(essentially trying to select records from one dataframe using a multi-value
re

### create example object
DF = data.frame(incident_num=c(1,2,2,3,4,4), incident_type=c("EMS", "FIRE",

class to include some data verifications? If so, do you have some basic
pointers for setting something like that up?
Really appreciate all your help thus far. Hopefully, one last advice email
will do the trick. Thanks.

The problem is that I cannot access S4 object slots using @ and a character
variable. I also cannot access a slot using the typical brackets since that
is what I am trying to define here. Kind of stuck. Thanks for any advice
you might have.
Best,

On Mon,
"a")] = 200 #would also like this to work -- any ideas?
Do you have any suggestions for getting assignments and brackets to work as
they would for data frames? Thanks so much for your help.
Best,
Markus

I created some S4 objects that are essentially data frame objects. The S4
object definitions were necessary to verify data integrity and force a
standardized data format. I am, however, finding myself redefining all the
typical generic functions so that I can still manipulate my S4 objects as if

I am trying to debug a package to submit it to CRAN and am getting a bunch

were automatically populated by the package.skeleton function. I find the
section on documentation to be pretty confusion in the R Extensions manual.
I am looking for some advice on licenses. Here is my situation:
