patching ?merge to allow the user to keep the order of one of the two data.frame objects merged
...dear R-devel list members.
Following an old (2002) thread from R-help (and having myself needing to
solve the same question):
https://stat.ethz.ch/pipermail/r-help/2002-October/026249.html
I patched the {base} function "merge.data.frame" to have it work with a new
parameter called "keep_order", and I hope you might consider including this
patch (or some variation of it) in some future R release.
Here is some explanation that might be added to the help file:
keep_order can accept the numbers 1 or 2, in which case it will make sure
> the resulting merged data.frame will be order...

Counting occurences of variables in a dataframe
Hi everybody,
I have a large dataframe similar to this one:
knames <-c('ab', 'aa', 'ac', 'ad', 'ab', 'ac', 'aa', 'ad','ae', 'af')
kdate <- as.Date( c('20111001', '20111102', '20101001', '20100315',
'20101201', '20110105', '20101001', '20110504',
