S4 Inheritance of environments
...2) Response to the is.* function seems to indicate that the object
does not know of its inheritance. ( Notably, the inherits function
works as expected. )
Here is a working illustration:
> # LIST
> setClass( 'inheritList', contains='list')
[1] "inheritList"
> inList <- new( 'inheritList' )
> class( inList )
[1] "inheritList"
attr(,"package")
[1] ".GlobalEnv"
> is.list( inList ) # TRUE
[1] TRUE
> slotNames(inList) # ".Data"
[1] ".Data"
> inherits(inList, 'list' )...

stupid R tricks
Hi all,
Just thought I'd post this (maybe) helpful tool I wrote. For people
like me who are bad at keeping a clean environment, it's a time-saver.
#simple command to get only one type of object in current environment
lstype<-function(type='closure'){
inlist<-ls(.GlobalEnv)
if (type=='function') type <-'closure'
typelist<-sapply(sapply(inlist,get),typeof)
return(names(typelist[typelist==type]))
}

A really simple data manipulation example
...er patient , with lab
sodium measurements. It has columns: PATIENT_ID, VISIT_NUM, and
SODIUM.
DEMO is a dataset with one row per patient, with demographic data.
It has columns: PATIENT_ID, GENDER.
Here's a simple example, the following paragraph of code is a
data processing function (dpf) :
inlist LABRESULTS DEMO ;
mergeby PATIENT_ID ;
if (SODIUM == -9) SODIUM = NULL ;
if (VISIT_NUM != 2) deleterow ;
select AVERAGE_SODIUM = avg(SODIUM) by GENDER ;
sendoff(RESULTS_DATASET) GENDER AVERAGE_SODIUM ;
turnoff; // just means end-of-paragraph , version 1.0 won't need this.
Can you guess wh...

using ls() to find a function
Dear R People:
Is there a way to find which objects are functions via ls(), please?
I'm sure that there is, but I'm not sure how.
Thanks,
Erin

Awk and Vilno
...trial data preparation and many other data situations, the
statistical programmer needs to merge and re-merge multiple input
files countless times. A syntax for merging files that is clear and
concise is very important for the statistical programmer's
productivity.
Here is how Vilno does it:
inlist dataset1 dataset2 dataset3 ;
joinby variable1 variable2 where ( var3<=var4 ) ;
Each column in a dataset has a variable name ( variable1, variable2,
var3, var4 ).
You are merging three input datafiles: dataset1, dataset2, and dataset3.
The joinby statement asks for a many-to-many join, rather l...
