Re: [R-pkg-devel] Using data.table in a package
Question one is a matter of personal preference. I personally stick to
explicitly state a double column depency with data.table.
Question two. Just replacing the dot by list is sufficient AFAIK.
Hope this helps

[R-pkg-devel] ggplot2 axis title with various size fonts
Is it possible to compose a string to be used as axis title in ggplot2, with the main part being drawn using one given font and font size, and the last part being drawn with another font and font size. See below for an example *my axis title **(units)* Currently struggling to achieve this. Thanks in advance for suggestions.

[R-pkg-devel] Fwd: PDF generation issue from manual page
Hi R gurus
Got an issue risen by CRAN about using unknown characters from Latex.
Here is the error message, in the context of PDF generated form manual pages
*Check: PDF version of manual, Result: WARNING LaTeX errors when creating
PDF version. This typically indicates Rd problems. LaTeX errors found:
! Undefined control sequence.\blacktriangleright *
* l.237 STRATUM $\blacktriangleright
$ LAYER\_3 ! Undefined control sequence.
\blacktriangleright *
* l.239 PHASING $\blacktriangleright
$ RUN ! Undefined control sequence.\blacktriangleright
*
* l.241 INTENT $\blacktriangleright
$ FEEDBACK*
I understand that the \blacktriangleright is an unknown control sequence
from latex ... and that sounds strange to me, as I uses it often in
vignettes without any issue so far.
I did some tests on my machine with R CMD Rd2pdf --force --output=x.pdf
man/*.Rd and it reproduces the issue.
In the incriminated manual page, the code generating this sequence is the
following
*\ifelse{latex}{\out{$\blacktriangleright$}}{\ifelse{html}{\out{}}{\u25b6}}*
Apparently I need to add the \usepackage{amssymb} to the manual page. Do
not know yet, how to achieve this.
Yours ideas and hints welcome and this point or any other solution to this
tricky issue.
I know that I can still change *\backtriangleright* with any available
control sequence and it will work. Indeed, not the way I prefer.
Really wish to get my *\blacktriangleright* display.
Best.
Neonira

Re: [R-pkg-devel] How to provide a finalized PDF file in a package?
Absolutely right Gabor. Thanks for suggestion Henrik. I tried to put the PDF directly in /inst/doc but apparently content is overwritten during vignettes generation, although there exists no name clash. Will probably have to try R.rsp!

[R-pkg-devel] How to provide a finalized PDF file in a package?
I create a cheat sheet using MS-OFFICE and converted it at a PDF format. I wonder in which folder of my package I should place it to be installed with the package. I tried instinctively in vignettes, but it doesn't seem to work correctly, as I do not find it back in my package installation folder. Best.
