ggplot2: Choosing colours
Dear useRs,
I'm trying to specify the colour of a factor with ggplot2. The example
below gets me close to what I want, but it's missing a legend.
Any ideas?
Thanks,
Thierry

dataset <- data.frame(x = rnorm(40), y = runif(40), z = gl(4, 10, labels
= LETTERS[1:4]))

How to cut data elements included in a text line
Hello,
assume I have an "unstructured" text line from a connection. Unfortunately,
it is in string format:
R> x
[1] "\talpha0\t-0.638\t0.4043\t0.4043\t-2.215\t-0.5765\t-0.137\t501\t2000"
How can I extract the data included in this string object "x" in order to
get the elements for the parameter vector called "alpha0", i.e.
-0.638 0.4043 0.0467

simultaneous computing
Hello,
which possibilities are available in R for simultaneous or parallel
computing?
I only could find biopara
(http://cran.r-project.org/src/contrib/Descriptions/biopara.html)
Are there other possibilities?
Are there special groups working on simultaneous computing with R?
Thanks

post_processor in rmarkdown not working
Dear all,
I'm trying to write a post_processor() for a custom rmarkdown format. The
goal of the post_processor() is to modify the latex file before it is
compiled. For some reason the post_processor() is not run. The
post_processor() does work when I run it manually on the tex file.
Any suggestions on what I'm doing wrong? Below is the relevant snippet of
the code. The full code is

problematic dev.off() after running examples without plots
Dear all,
When running R CMD check on our package, we get an error on the examples.
Error in grDevices::dev.off() :
cannot shut down device 1 (the null device)
None of the examples in our package generates plots. grDevices::dev.off()
is code added by R CMD check. A workaround is to have at least one example
which has some plot. Is there a better solution? We are using R 3.5.1

density estimate
Hi,
I have a vector or random variables and I'm estimating the density using
"bkde" function in the KernSmooth package. The out put contains two vectors
(x and y), and the R documentation calls y as the density estimates, but my
y-values are not exact density etstimates (since these are numbers larger
than 1)! what is y here? Is it possible to get the true estimated density at

Today I got this error message (R 3.6.1) when installing my package:

My package was using setOldClass("inla") and exported the "inla" class via
the NAMESPACE. It imports functions from the INLA package. Older versions
of the INLA package did not

Problem with adding slots to S4 object
Dear all,
I'm trying to create a virtual S4 class with some subclasses. I noticed
that adding slots to this class increases the memory use and slows the
functions down. Note that I'm adding very small slots (integer or character
both of length 1).
I've made a reproducible example at
https://github.com/ThierryO/testvirtualclass. The R CMD check --as-cran
fails on the tests.

reverse object creation
Dear all,
this is my first message to this mailing list - please advise if it is not
the right place for the subject
I've been using R very intensively the last 3-4 years and one of the most
tedious tasks is modification of lookup or conversion tables
So far, I have not found functions that create the commands for creating
objects (vectors, data frames) based on the objects themselves -

UTF8 markdown vignette
Dear all,
I'm trying to use a Markdown vignette with UTF-8 encoding. It compiles well when knitting the vignette in RStudio, but it fails to recognize the UTF-8 settings when building the source package. Can someone point out what I'm doing wrong? I tried to put the relevant information below.

Problem with adding slots to S4 object
There are too many arguments in the signature of the my_inla generic. The
signature defaults to every argument in the formals, which are probably
already over-specified. Typically, one defines a generic with the formals
(x, ...), or perhaps in this case (x, model, ...), but more on that below
Unrelated to this issue, the my_inla generic is defined incorrectly. It
should call

If you tell me how to update R itself automatically, I will go for your
advice.
I am not aware of any method to do it...
