QUESTION
This is a followup or more a simplification of this question Error: File header.tex not found in resource path in a rmarkdown generated pdf report from a shiny app
With this Rmarkdown code I can achieve what I want:
logo.png
report.Rmd
...ANSWER
Answered 2022-Apr-09 at 16:36Basically you already figured out what's the issue. Hence one approach to fix your issue would be to do copy both the report template and the logo to the same temporary directory.

I am Arch GNU/Linux user who usually manages almost every package with pacman; I manage TeX and LaTeX-related things with tlmgr. I installed tlmgr from source.
I am writing paper. I would like to use bibliography.

from the AUR, as suggest in this answer.
This made my biber

QUESTION
- I am a new user of
Scilab
and I am not a mathematician. - As my end goal, I want to calculate (and plot) the derivative of a piece-wise defined function, see here.
- I tried to start small and just use a simple (continuous) function:
f(x) = 3*x
. - My Google-Fu lead me to the numderivative function.
- Problem: It seems that I do not understand how the argument
x
works since the result is not a 1D-array, instead, it is a matrix. - Update 1: Maybe I use the wrong function and
diff
is the way to go. But what is then the purpose ofnumderivative
?
PS: Is this the right place to ask Scilab-related questions? It seems that there are several StackOverflow communities where Scilab-related questions are asked.
...ANSWER
Answered 2021-Sep-06 at 08:46numderivative(f,x) will give you the approximated derivative/Jacobian of f at the single vector x. For your example it yields 3 times the identity matrix, which is the expected result since f(x)=3*x. If you rather need the derivative of f considered as a function of a single scalar variable at x=1 and x=2, then numderivative is not convenient as you would have to make an explicit loop. Just code the formula yourself (here first order formula) :
QUESTION
I'm trying to use packages that require Rcpp

check from this page but I get the following error:
ANSWER
Answered 2022-Feb-10 at 21:07Currently (2022-02-05), CRAN builds R binaries for Apple silicon using Apple clang
(from Command Line Tools for Xcode 12.4) and an experimental build of gfortran
.
If you obtain R from CRAN (i.e., here), then you need to replicate CRAN's compiler setup on your system before building R packages that contain C/C++/Fortran code from their sources (and before using Rcpp
, etc.). This requirement ensures that your package builds are compatible with R itself.
A further complication is the fact that Apple clang
doesn't support OpenMP, so you need to do even more work to compile programs that make use of multithreading. You could circumvent the issue by building R itself and all R packages from sources with LLVM clang
, which does support OpenMP, but this approach is onerous and "for experts only". There is another approach that has been tested by a few people, including Simon Urbanek, the maintainer of R for macOS. It is experimental and also "for experts only", but seems to work on my machine and is simpler than trying to build R yourself.
Warning: These instructions come with no warranty and could break at any time. They assume some level of familiarity with C/C++/Fortran program compilation, Makefile syntax, and Unix shells. As usual, sudo
at your own risk.
I will try to address compilers and OpenMP support at the same time. I am going to assume that you are starting from nothing. Feel free to skip steps you've already taken, though you might find a fresh start helpful.
I've tested these instructions on a machine running Big Sur, and at least one person has tested them on a machine running Monterey. I would be glad to hear from others.
Download an R binary from CRAN here and install. Be sure to select the binary built for Apple silicon.

QUESTION
Can LaTeX escapes for accents be used in Rd
files? I tried the standard \'e
and many variants (\'{e}
, {\'e}
, \\'e
, \\'{e}
, {\\'e}
, etc.), but none is rendered as an accented character in the PDF or HTML output.
I want my References section (i.e. \references{}
) to be rendered with accented characters, but I do not want to type non-ASCII characters in my Rd
files. Is there good/recommended practice? Should I simply replace non-ASCII characters with their ASCII equivalents (é → e, ø → o)?
To be clear, I know it is possible to type accented characters (e.g., é
) directly in UTF-8-encoded files, but I would prefer to keep ASCII-encoded files.
This question is not about
- how to type special/accented letters in LaTeX
- how to use UTF-8 in LaTeX
- accents/special characters in R Markdown
or variants.

I am new to angular and working on reactive form.
I have a html table in which by looping through I have generated controls
I want to add validation based on following cases
- When this page loads than by default Save button should be disabled( which I have achieved by used
[disabled]="!myform.valid"
- Save button should enable only when user enter value in any of text boxes or select check box in that particular row. Checkbox select and add value in text box should not allow to user. Either checkbox should be selected or user can enter value in any of text-boxes.
I tried this to achieve

After understanding the whole question, we could resolve it by adding a new validator to each form item.

Code Context:
- Phaser3

- Loading state of game room before socket connects
- Generating the NPC's and players

Issue:
- Cannot access the sprite property, and in general seems like the object wasn't created in the first place
I have the socket listening in Phaser3's "create()" function for "universeState" after it has connected to the socket server. index.js:

QUESTION
I'm creating an R Markdown document using the 'papaja' package and the 'apa7' LaTeX template. When used together, the latter package and template currently produce a conflict due to duplicated \author
and \affiliation
fields in the tex
file. Earlier, a method was found to resolve this conflict that worked by adding the following LaTeX commands to the preamble (through header-includes
in the YAML header):
ANSWER
Answered 2022-Jan-08 at 23:41I found a book on the Papaja package. That link will bring you to the YAML section. I think this is what you were looking for.
First, there doesn't appear to be an association for APA 7, unless you have the development version of Papaja
. That being said, there is a ticket on this in their main github.
If you set the output to apa6_docx, this "and &" error won't be there. (And even if it were, you could have deleted it.) You can save it as a PDF from there. I'm not sure if this is an option for you, but I thought I would mention it.
This is what it states about subsequent authors (and much more).
