timings for examples in R CMD check
I'm having a very hard time making R CMD check produce a clean check on
examples because of the timings inserted into examples by R CMD check.
I am getting a difference on every example output caused by timing
information being inserted by 'R CMD check'.
The current 'Writing R Extensions' manual[1] states on p. 14:

How to call R from C
Hi all!
I read R Extensions manual.
But still I am not sure how to call R functions from C.
Would any of you give me a sample C code to show how to call R functions - for instance, time series functions - from C in the embedded way of C code?

tempdir() documentation or real bug ?
?tempdir says
By default, ?tmpdir? will be the directory given by ?tempdir()?.
This will be a subdirectory of the temporary directory found by
the following rule. The environment variables ?TMPDIR?, ?TMP? and
?TEMP? are checked in turn and the first found which points to a
writable directory is used: if none succeeds ?/tmp? is used.

Support for high DPI 4K screens
I was recently testing R and RStudio on a high dpi 4K monitor under Windows and noticed that the plot window cannot be scaled or zoomed without affecting the relative sizing of all plot elements (line widths, font sizes, legend spacing etc). RStudio seems to try to overcome this by enabling dpi scaling for the plot window on high dpi screens, but this results in really fuzzy text and graphics

Dear Colleagues/Developers/R enthusiasts,
Would it be possible to develop a code of conduct (CoC) document for
R lists, CRAN submissions that all developers/maintainers to follow?
This may help all of us to better communicate and move forward together.
There is a similar effort from Python community, here are the links:

Identifying outliers in non-normally distributed data
Hello,
I've been searching for a method for identify outliers for quite some
time now. The complication is that I cannot assume that my data is
normally distributed nor symmetrical (i.e. some distributions might
have one longer tail) so I have not been able to find any good tests.
The Walsh's Test (http://www.statistics4u.info/

machine learning use case. My requirement is to include R-core package in

Fitting ACD model
Hi - I'm wondering if there is any existing package in R that
facilitates ACD (Autoregressive Conditional Duration) model. I
googled. Apparently there were packages dynamo and fACD. However, they
do not seem to be on any CRAN. I am wondering if anyone could point me
to an existing package (if any). Thank you.

loading data into ZOO
Hello,
I have a simple question. I am trying to load data into a zoo object. I have
the data in CSV format as follows
SYMBOL DATE TIME PRICE
XX YYYYMMDD HH:MM:SS n.nn
and there are multiple symbols in this one data frame.
My question is, do I need to merge DATE and TIME before loading them or can
I specify multiple index.column or index.name fields?

Snippets from other packages/ License
Hello,
I want to use a function from another package (which is GPL>=3), about 20 lines of code, in my own package.
I somewhat hesitate to depend on the entire package just for this single function, but of course I want to credit the original authors.
What would be the best way to do that? Where should I put that credit? Or should I proceed completely different?
Best,

Handling of irregular time series in lineChart
Hi,
I realized that when I have irregular series to feed into lineChart,
the interval of each point in the chart does not seem to take care of
irregular time interval I specified in my input xts time series. But
rather, lineChart seems to take each point as equal spaced time
series. For example, I have the following code:
library(quantmod)
options(digits.sec=3)

a^b when a is large and b < 1 (64bit R on windows 7)
Hi,
I'm getting some strange behaviour when trying to use the power operator
(a^b) when a is large and b is less than one:
big <- .Machine$double.xmax
big
big^0.5
sqrt(big)
> big <- 1.797693134862315708384e+308
> big^0.5
[1] Inf
> sqrt(big)
[1] 1.340781e+154
I'm guessing that this behaviour is not expected, or am I missing
something about ^?
Cheers

Sending lists using .C
Hi,
I posted around a week ago and I will try this time with a more detailed
description.
I am converting R code to C code to boost speed as currently it takes a few
days to run. Now I will try describe this with as detail as possible.
I have a list of size 47. Each element of the list is itself a list of size
7, and each of these lists are arbitrarily long lists of integers.
