Where can i find the latex file l3backend.sty. I installed l3backend package via Miktex but still the file is not there. I get error message l3backend.sty not found Please anyone help. I am stuck
I think there is no l3backend.sty. Whether your tex file file was calling l3backend.sty you can skip by \expandafter. Try in your preamble
\expandafter\def\csname
ver#l3backend.sty\endcsname{}

I've downloaded miktex, tinytex and ghostscript and tried changing the path since the problem seems to be in the path. So far nothing has helped me and I would appreciate some help:
This is my error message:
Error: LaTeX failed to compile Uebungsblatt1_MAT183.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See Uebungsblatt1_MAT183.log for more info.
In addition: Warning message:
In has_crop_tools() :
Tool(s) not installed or not in PATH: ghostcript
-> As a result, figure cropping will be disabled.
Execution halted
Any help or try to troubleshoot would be appreciated. Thank you
I have figured this out for myself by now: what I did was that I first uninstalled MikTex and tinytex because they apparently were clashing somehow. Then I reinstalled tinytex - this time typing it directly into the console instead of using the installing tool from R - so I typed everything at a time and executed it. It had me restart R and updated some files then too. Since then it has worked flawlessly. Also, I did the same on my other computer (MacBook) where it didn't work so chances are pretty good that that might solve that same problem for someone else out there. Thanks to everybody who tried helping and improved the question or sent responses.
Which code you tried to compile?
Sometimes this error rise when a letter is missed in the \begin function. If you tried to compile an array, do not forget to use the same letters as rows you need.
Example:
$$|x|=\left\{\begin{array}{ll} -x & \text{si }x\le 0\\ x & \text{si }x\ge 0 \end{array}\right.$$
While using R , my file is saved on desktop When I run
This code it gives me the above error
Setwd(“users/user name/desktop/“)
Isuggest that to check the work directory, and it is better to read any file on the same work space you choose
from session -> set working directory ->choose directory
I hope my Answer help you.
I am running the command: devtools::use_testthat()
and I get the error:
Error: Could not find package root.
Why this happens?
devtools appears now to require the user to setwd("~/path/to/package"), even if functions like devtools::release() have the pkg= parameter set correctly.
My problem was very similar, but running devtools::document(setwd(...)). The only thing that worked for me:
I copied the DESCRIPTION file from another package (https://github.com/filipezabala/voice);
I ran devtools::document(setwd(...)) again;
After that, I edited the DESCRIPTION file and ran again devtools::document(setwd(...)).
I have been using roxygen2::roxygenise quite successfully with my package to build exported and imported functions. However, I recently ran into this error which I am unable to resolve:
> roxygen2::roxygenise()
First time using roxygen2. Upgrading automatically...
Error: File file does not exist
This is not the first time I have used roxygen2 with this package. In addition, I am not quite sure what "File file does not exist" means. Has anyone else seen this and been able to resolve it?
I think you have to set the working directory of R to be the package folder
I got the same error when using:
roxygen2::roxygenise("mypackage")
But, I didn't get the error when I instead used:
library(roxygen2)
roxygenise()
I know this is no explanation and I can't comment upon whether this works beyond my case.
I am struggeling with reading DICOM files in R. I have installed the oro.dicom package, using:
install.packages("oro.dicom", repos="https://cran.cnr.berkeley.edu/")
I have set the working directory to where the files are located.
When trying to read a dicom file, using...
slice=readDICOM("IM-0001-0011.dcm")
... I get the following error message:
Error: could not find function "readDICOM"
Can someone help?
Thank you,
Lena
You should load package with library(oro.dicom) fisrt before you will use functions from that package,
