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? [[alternative HTML version deleted]]

timings for examples in R CMD check
....1.0, 3.1.1, and R-devel. I would assume from the documentation that there should be a way to get a clean check, without the timing diffs.

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

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/ fundsta...liertest.html#), as I understand assumes that the

Which, in part, is why R has so much control over the types of graphic devices you create, and how you choose to control them. Regards, Brian -- Brian G.

establishing a Code of Conduct for R
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: * https://mail.python.org/pipermail/scipy-dev/2017-August/022044.html *

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. -r

mclust: modelNames("E") vs modelNames=("V")
Hi, I'm trying to use the library mclust for gaussian mixture on a numeric vector. The function Mclust(data,G=3) is working fine but the fitting is not optimal and is using modelNames="E". When I'm trying Mclust(data,G=3,modelName="V") I have the following message: Error in if (Sumry$G > 1) ans[c(orderedNames, "z")] else ans[orderedNames] : argument is

Performance monitoring tools
Hello, Are there any good tools available for monitoring the performance of R? I'm wanting to capture things such as time elapsed in evaluating an expression, memory usage over time (or operation), and so on. I could build my own but would like to follow established practice, if there is one. Thank you, Patrick [[alternative HTML version deleted]]

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, Felix

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) t0 <-

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 ^?
