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]]

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: If directory tests has a subdirectory Examples

?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. Unfortunately, it doesn't seem to

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

I downloaded the iid.test, but I can't run it. I get the following message: Error: could not find function "iid.test" Where am I supposed to save this package in order that it works? Thanks, EZ [[alternative HTML version deleted]]

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 *

Dear Listmembers, I'm looking for a convenient way to read csv-data which are stored in variables of data frames. I'm working with nested csv-data: one of the columns of the first table stores a long string containing a second csv-coded table. My problem is to parse that second-order csv-table. As the read.csv command requires a link to a file, I couldn't get it to read the

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

Hello, I am trying to write the default "OrchardSprays" R data frame into HDFS using the "rhdfs" package. I want to write this data frame directly into HDFS without first storing it into any file in local file system. Which rhdfs command i should use? Can some one help me? I am very new to R and rhdfs.

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]]

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

Hi I want to include ascii art in a function documentation which should look as follow: ,---- | +------+------+------+ | | 1/16 | 1/16 | 1/16 | | +------+------+------+ | | 1/16 | 8/16 | 1/16 | | +------+------+------+ | | 1/16 | 1/16 | 1/16 | | +------+------+------+ `---- to keep the monospaced font even in html, I decided to use \code{}: ,---- | \code{+------+------+------+} | | \code{|

Hi, I am a beginner to R language and currently exploring R to use it for machine learning use case. My requirement is to include R-core package in my embedded linux box which runs on customized Monta Vista Linux with kernel 2.6.32 and it has multi-core MIPS processor. I hope, there is NO pre-compiled R package for Monta vista linux and mips processor. So, i am trying to do cross compilation

Dear R community, I am in a quest for a co-mentor, expert in R, for the following GSoC18 project proposal: https://github.com/rstats-gsoc/gsoc2018/wiki/Sampling-and-volume-approximation Thank you in advance for your feedback. Best, Vissarion Fisikopoulos

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

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?

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 <-

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 ^?

Hi All, OK, in the "back to the drawing board" department, I found what looks like a much better solution to using R in Java. Renjin. Looking at the docs and then trying a quick example, didn't quite work. Of course I'm missing something. Although I'm telling the engine to require ("biotools") just like I would in R itself, when I get to the line of code that
