derivative of atan(x) and similar functions
Dear R experts. 'D()' function recognizes some of the analitical functions, such as sin, cos, etc. But I'd like to take analytical derivatives from asin, atan etc. functions. Are there any R packages providing that features? Thanks. -- Timur.

ZINB multi-level model using MCMCglmm
Hi, I am Olga Viedma. I am running a Zero-inflated negative binomial (ZINB) multi-level model using MCMCglmm package. I have a doubt. Can I use the "Liab" outputs as fitted data, instead of the predicted values from "predict"? The liab outputs fit very well with the observed data, whereas the predicted values are so bad. Thanks in advance, Olga Viedma D . Olga

Demo for linking native routines between R packages
Dear R developers, I want to advertise a small project for the educational purpose to show people how to link native routines. In R programming, we need to link to native routines in C, C++, or Fortran from the R environment. In most cases, the linking works within one package, namely the R code in a package calls the native code in the same package. This is not necessarily always the case.

Demo for linking native routines between R packages
Dear Davis, Thank you a lot for sharing this, and I am happy that I was not the only one who need to do it once to learn:) I proposed to add my repo to the manual. I think it makes sense to add both of ours, if possible, or we could merge them together and add that to the manual. Long-term URL stability is apparently an issue, but I think we may find a solution there. Anyway, thanks a lot for

"R is not a validated software package.."
Dear All, discussing with a statistician of a pharmaceutical company I received this answer about the statistical package that I have planned to use: As R is not a validated software package, we would like to ask if it would rather be possible for you to use SAS, SPSS or another approved statistical software system. Could someone suggest me a 'polite' answer? TIA Giovanni -- dr.

tidyverse repeating error: "object 'rlang_mut_env_parent' not found"
UseRs, When doing some data manipulations using the tidyverse, I am repeatedly getting the same error message in now three separate situations. I can write up a reproducible example, but want to lay out the high-level issues in case someone recognizes exactly what is happening here. The error is: Error in mut_env_parent(overscope$.top_env, lexical_env) : object 'rlang_mut_env_parent'

R & Java
Hey guys, I'm a (Java) integration architect. We are currently stuck with SAS but I'd be happy to switch that to R! (of course ;-). Now, a big argument for the latter, is that we can integrate it seamlessly with all our existing (java) apps. Therefore: has anyone heard of a java API (like SAS has it's Java API for enterprise integration) or a Service we can call (e.g. a web service,

Passing options as lists
Hi, I apologize if this has previously been posted. I've just subscribed to the R-help digest. I'm writing a plotting function that uses layout() to plot several different plots on the same device. This function uses plot(), image(), and a custom function that uses text(). Each cell of the layout needs different par() parameters, so what I'd like to do is pass them as lists:

legend
I think I'm missing something tonight in the usage of 'legend': plot(0, type="n") legend(locator(1), month.abb[1:5], pch=15, col=1:5) gives me something similar to what I want. But legend(locator(1), month.abb[1:5], fill=T, col=1:5) gives me 5 black boxes. What am I doing wrong? Thank you, > version _ platform i686-pc-linux-gnu arch i686 os

Example Syntax for if - then- and - else Statements
Hello R users, I am a fairly new R user, however, one of the problems I am having is the use of applying if-, and-, then-, else- statements in R against datasets & dataframe. Rtips mentions it, but without simple examples I am not quite sure what my syntax should look like. I am particularly interested in syntax that can be used with the transform function. for example if foo[,1] ==
