Recently in our R 3.1.0 installation the package formatR was upgraded to version 1.0, doing my usual thing, I got the following error, and the destination html file was not generated. What can I do if I want to stay at the current formatR version? Jun Error: unrecognized fields specified in html_dependency: attachment In addition: Warning messages: 1:...

This is an announcement of the release of an R package 'formatR', which can help us format our R code to make it more human-readable. If you have ugly (I mean unformatted) R code like this: ?# rotation of the word "Animation" # in a loop; change the angle and color # step by step for (i in 1:360) { ? # redraw the plot again and again plot(1,an...

...irst attempt ended up with two of the four dependencies installed so only the Rgtk related items would be needed this time. Went into synaptic and found r-cran-rgtk2. Okay. Sounded likely so I installed it successfully. Using a root terminal session I went back into R and ran install.packages("formatR"). Pulled in two dependencies plus the main choice. Rejected one and kept two when it came time to install but still installed successfully, or so it seemed when I ran library(formatR). Go figure. A copy of the message run follows. Any comments or suggestions will be of interest. > install...

On a system with IEEE_754 undefined, I run into an bug, when the value of an element of the first argument (e.g., x[0]) of formatReal() is NA: 1. (format.c:235) if (!R_FINITE ..) gives nanflag=1 (!naflag remains 0) 2. (format.c:272..288) *m gets an value of -2147483643 (from the format fiddling, should not matter to us) 3. (format.c:289) because naflag is zero, m does not get the value of...

Hi, I want to print real numbers in C code with different values for digits. How to do that? As I have understood, what I should do is to call StringFromReal() which calls FormatReal(), that one suggests the parameters (width, decimal places and exponential form). FormatReal() includes eps = pow(10.0, -(double)R_print.digits); So I guess I have to change the value of R_print.digits. R_print.digits is defined in include/Print.h in the package source, but unfortunately...

Hi list, Could anyone recommend some good website for formatting R code? For example, when you copy paste R code to gmail and back to R, it loses its format, the dash symbol causes errors. I've had someone used it to format my code here on the list, but can't find it anymore. Mike [[alternative HTML version deleted]]

..., while testing this bug I found another related issue: > format(complex(real=10, imaginary=4), digits = 1); [1] "10+0i" I think this should've been "10+4i". I have entered this as a bug #15427. But a patch for formatComplex() would be a bigger change, than the patch for formatReal() I made. So, before I start, I would like to gauge your opinion. Do you agree it is a bug?

I needed to clean someone else code and run it through tidy.source. It encountered a number of hangups which after some experimentation lead me to suspect that the culprit is # symbol when it is a part of literal string. For example if i copy the following to the clipboard confuse.tidy <-    function() {   txt <- 'abra # cadabra' } and run with default arguments >tidy.source()

Hello, Can anyone provide or point me to a good setup for the listings latex package that would produce nice R-syntax highlighting? I am using an example I found in internet for setting up listings like this: \lstset{ language=R, basicstyle=\scriptsize\ttfamily, commentstyle=\ttfamily\color{gray}, numbers=left, numberstyle=\ttfamily\color{red}\footnotesize, stepnumber=1, numbersep=5pt,

Buenos días: Por favor, ¿alguien puede indicarme si sólo hay que documentar las funciones visibles del paquete?. Además, ¿cómo se consigue que sólo algunas de las funciones estén visibles?. ¿Cómo manejo el namespaces para ello?. Gracias. Eva [[alternative HTML version deleted]]
