Hello Jeff,
I kept fooling with this, and also looking around the web and I actually
found something on stackoverflow, which does what I had in mind. You

Hello,
subsets of association rules (with respect to support, confidence, lift, or
items) can be obtained with the arules::subset() function; e.g.
rm(list = ls(all.names = TRUE))

set.seed(42)
x <- lapply(X = 1:500, FUN = function(i)
sample(x = 1:10, size = sample(1:5,
A vignette has been added to the package. I hope that even those who don’t use
the package will find its discussion of trellis graphics useful. Otherwise,
this is a minor update that fixes some bugs and adds a few small features. See
the NEWS file for details. As always, comments and suggestions
If you think you might want to put this function into a package, it would be
much better to use gsub instead of passing the job off to an external program,
because non-POSIX operating systems (Windows) will be a headache to support.

No you may not.
I suggest that you *first search before posting* -- e.g. on "R package
moments of distributions" -- where you would find the package
"moments" that apparently already does exactly what you suggest (there
are some other packages as well). You could also first search the CRAN

Today I need to compute the means for some distributions... and there's no easy
way to do it!
I mean (no pun intended), there is (d,p,r,q) for all distributions (like:
dgamma, pgamma, rgamma, qgamma; dchisq, pchisq, rchisq, dchisp; etc), but there
is no "m"-functions, like a mgamma to get the m
At the risk of being redundant, the command prcomp(pcl, scale.=T) is the same
as the command print(prcomp(pcl, scale.=T)). This passes the results of

print.prcomp() is programmed to display) and then throws them away. To save t

Hi Nick,
"prcomp" returns an object of class "prcomp" so when you simply 'print' the
object it gets passed to the "print.prcomp" function. If you want to see
all the objects you should assign the results to an object.
Regards,
Charles

Perhaps use the correct function. (Just one little letter off...)

Not sure what the issue is with the provided code but note:
library(lubridate)
lubridate::dmy_hm("Thu, 25 Aug 2016 6:34 PM")
[1] "2016-08-25 18:34:00 UTC"
Though if you go that route: set the TZ because on the timestamp it is
ambiguous.
