Executing Shell Script via Automator - r

via Terminal/Totalterminal or iTerm, this script works very well:
cd ~/go/to/dir/ && R -e "shiny::runApp("/go/to/dir", launch.browser=TRUE)"
but as/in a App via Automator, the second Part wont work.
In Automator: run Shell-Script.
Where is the difference of "normal" Terminal and the Terminal used by Automator.
In both /bin/bash

Is r on the path in Automator? If not, replace r with the full path like /usr/local/bin/r (shown by which r).

Getting RStudio in Docker Environment Command Window as opposed to browser?

This is a question related to using docker to run scripts of RStudio. The problem I'm having is that the person evaluating the results I'm getting wants to have it so that they type in ./test.sh in the command window, that runs my R script, and a csv of my results prints out to the local directory.
Is it possible to get the rocker rstudio to appear in the command window as opposed to having to log into the browser to use rstudio? It seems all the resources online say something along the lines of put -p 8002:8787 and -d in the docker line of code, but this makes it so you have to go to a local browser to actually run your R script.
I've found this code snippet works, but is there an alternative to using \bin\bash at the end so that the rstudio commands can just stay in the window?
$ docker run -e PASSWORD=MYPASSWORD -v "$(pwd):/data:ro" -v "$(pwd):/workdir" -it thatguy /bin/bash
Or, better yet, is there a way to put this docker run command in my Dockerfile so that when I run my $ docker build this line just runs automatically?

R Markdown: Can't access Bash command installed through Conda/Anaconda

I'm exploring some bioinformatics data and I like to use R notebooks (i.e. Rmarkdown) when I can. Right now, I need to use a command line tool to analyze a VCF file and I would like to do it through a Bash code chunk in the Rmarkdown notebook.
The problem is that the command I want to use was installed with conda into my conda environment. The tool is bcftools. When I try to access this command, I get this error (code chunk commented out to show rmarkdown code chunk format):
#```{bash}
bcftools view -H test.vcf.gz
#```
/var/folders/9l/phf62p1s0cxgnzp4hgl7hy8h0000gn/T/RtmplzEvEh/chunk-code-6869322acde0.txt: line 3: bcftools: command not found
Whereas if I run from Terminal, I get output (using conda environment called "binfo"):
> bcftools view -H test.vcf.gz | head -n 3
chr10 78484538 . A C . PASS DP=57;SOMATIC;SS=2;SSC=16;GPV=1;SPV=0.024109 GT:GQ:DP:RD:AD:FREQ:DP4 0/0:.:34:33:0:0%:0,33,0,0 0/1:.:23:19:4:17.39%:1,18,0,4

(binfo)
So, how do I access tools installed with conda/in my conda env from an R notebook/Rmarkdown bash code chunk? I searched for quite a while and could not find anyone talking about running conda commands in a shell chunk in Rmarkdown. Any help would be appreciated because I like the R notebook format for exploratory analysis.
Passing Arguments to Engines
If your Conda is properly configured to work in bash, then you can use engine.opts to tell bash to launch in login mode (i.e., source your .bash_profile (Mac) or .bashrc (Linux)):
bash
```{bash engine.opts='-l'}
bcftools view -H test.vcf.gz
```
zsh
If working with zsh (e.g., Mac OS 10.15 Catalina users), then the interactive flag, --interactive|-i is what you want (Credit: #Leo).
```{zsh engine.opts='-i'}
bcftools view -H test.vcf.gz
```
Again, this presumes you've previously run conda init zsh to set up Conda to work with the shell.
Note on Reproducibility
Since reproducibility is usually a concern in scientific work, I will add that you may want to do something to capture the state of your Conda environment. For example, if you are working in version control, then commit a conda env export > environment.yaml. Another option would be to output that info directly at the end of the Rmd, like what is usually done with sessionInfo(). That is,
```{bash engine.opts='-l', comment=NA}
conda env export
```
where the comment=NA is so that the output can be cleanly copied from the rendered version.
Quick solution for bash: prepend the following init script into your Bash scripts.
eval "$(command conda 'shell.bash' 'hook' 2> /dev/null)"
# you may need to activate the "base" environment explicitly
conda activate base
Detail
When you open your terminal, an interactive shell is spawned. But your script is run in a non-interactive shell. Bash configuration file ~/.bashrc will not be used for the scripts, which skips the conda initialization and your "base" environment is not exposed into PATH.

Rscript not working with packaged R for AWS Lambda

I'm trying to run an R script on the command line of an AWS EC2 instance using packaged R binaries and libraries (without installation) -- the point is to test the script for deployment to AWS Lambda. I followed these instructions. The instructions are for packaging up all the R binaries and libraries in a zip file and moving everything to a Amazon EC2 instance for testing. I unzipped everything on the new machine, ran 'sudo yum update' on the machine, and set R's environment variables to point to the proper location:
export R_HOME=$HOME
export LD_LIBRARY_PATH=$HOME/lib
NOTE: $HOME is equal to /home/ec2-user.
I created this hello_world.R file to test:
#!/home/ec2-user/bin/Rscript
print ("Hello World!")
But when I ran this:
ec2-user$ Rscript hello_world.R
I got the following error:
Rscript execution error: No such file or directory
So I checked the path, but everything checks out:
ec2-user$ whereis Rscript
Rscript: /home/ec2-user/bin/Rscript
ec2-user$ whereis R
R: /home/ec2-user/bin/R /home/ec2-user/R
But when I tried to evaluate an expression using Rscript at the command line, I got this:
ec2-user$ Rscript -e "" --verbose
running
'/usr/lib64/R/bin/R --slave --no-restore -e '
Rscript execution error: No such file or directory
It seems Rscript is still looking for R in the default location '/usr/lib64/R/bin/R' even though my R_HOME variable is set to '/home/ec2-user':
ec2-user$ echo $R_HOME
/home/ec2-user
I've found sprinkles of support, but I can't find anything that addresses my specific issue. Some people have suggested reinstalling R, but my understanding is, for the purposes of Lambda, everything needs to be self-contained so I installed R on a separate EC2 instance, then packaged it up. I should mention that everything runs fine on the machine where R was installed with the package manager.
SOLUTION: Posted my solution in the answers.
It thinkt it is staring at you right there:
ec2-user$ whereis R
R: /home/ec2-user/bin/R /home/ec2-user/R
is where you put R -- however it was built for / expects this:
ec2-user$ Rscript -e "" --verbose
running
'/usr/lib64/R/bin/R --slave --no-restore -e '
These paths are not the same. The real error may be your assumption that you could just relocate the built and configured R installation to a different directory. You can't.
You could build R for the new (known) path and install that. On a system where the configured-for and installed-at path are the same, all is good:
$ Rscript -e "q()" --verbose
running
'/usr/lib/R/bin/R --slave --no-restore -e q()'
$
This blog post walks through a similar problem and offers a potential solution. I also had to implement part of the solution from this post.
I changed the very first line of R's source code from this:
#!/bin/sh
# Shell wrapper for R executable.
R_HOME_DIR=${R_ROOT_DIR}/lib64${R_ROOT_DIR}
To this:
R_HOME_DIR=${RHOME}/lib64${R_ROOT_DIR}
I'll explain why below.
NOTE -- The rest of the code is:
if test "${R_HOME_DIR}" = "${R_ROOT_DIR}/lib64${R_ROOT_DIR}"; then
case "linux-gnu" in
linux*)
run_arch=`uname -m`
case "$run_arch" in
x86_64|mips64|ppc64|powerpc64|sparc64|s390x)
libnn=lib64
libnn_fallback=lib
;;
*)
libnn=lib
libnn_fallback=lib64
;;
esac
if [ -x "${R_ROOT_DIR}/${libnn}${R_ROOT_DIR}/bin/exec${R_ROOT_DIR}" ]; then
R_HOME_DIR="${R_ROOT_DIR}/${libnn}${R_ROOT_DIR}"
elif [ -x "${R_ROOT_DIR}/${libnn_fallback}${R_ROOT_DIR}/bin/exec${R_ROOT_DIR}" ]; then
R_HOME_DIR="${R_ROOT_DIR}/${libnn_fallback}${R_ROOT_DIR}"
## else -- leave alone (might be a sub-arch)
fi
;;
esac
fi
if test -n "${R_HOME}" && \
test "${R_HOME}" != "${R_HOME_DIR}"; then
echo "WARNING: ignoring environment value of R_HOME"
fi
R_HOME="${R_HOME_DIR}"
export R_HOME
You can see at the bottom, the code sets R_HOME equal to R_HOME_DIR, which it originally assigned based on R_ROOT_DIR.
No matter what you set the R_HOME_DIR or R_HOME variable to, R resets everything using the R_ROOT_DIR variable.
With the change, I can set all my environment variables:
export RHOME=$PWD/R #/home/ec2-user/R
export R_HOME=$PWD/R #/home/ec2-user/R
export R_ROOT_DIR=/R #/R
I set RHOME to my working directory where the R package sits. RHOME basically acts as a prefix, in my case, it's /home/ec2-user/.
Also, Rscript appends /R/bin to whatever RHOME is, so now I can properly run...
Rscript hello_world.R
...on the command line. Rscript knows where to find R, which knows where to find all it's stuff.
I feel like packaging up R to run in a portable self-contained folder, without using Docker or something, should be easier than this, so if anyone has a better way of doing this, I'd really appreciate it.
Another more quickly method:
create same folder /usr/lib/R/bin/
then put R into this folder.

Shiny script from Ubuntu bash

I wanted to run with crontab (the system daemon used to execute desired tasks at certain times) a shiny script.
I first tried running sh Autorun.sh, being in the file:
R
shiny::runApp(...)
but that didn't work
I also tried writting directly Rscript shiny::runApp(...) but it also doesn't work
Any ideas?
To run code using R on shell, you must use the -e option, which stands for expression. The same thing can be done via Rscript.
The correct syntax is then:
R -e 'shiny::runApp(...)'
Care must be taken with the quotes if there are any in the expression being used.
For more information on other command-line options, check An Introduction to R - Appendix B.

How can I print R documentation from a Linux command shell (e.g. bash)?

How can I check documentation for R code from a Linux command shell such as bash? I DO NOT mean an interactive session.
With Perl, I can use perldoc to print out documentation at the command line:
perldoc lib
I was hoping for something simple like that for R. I don't always want to pull up a full interactive R session just to look up some documentation.
There might be other ways, but one that works for me is using the -e flag to execute code on the command line. I also use the --slave flag, which prevents anything from being printed to standard output (e.g. no R startup messages, etc.):
R --slave -e '?function'
I actually created a super small script I call rdoc to act like a simple R version of perldoc:
#!/bin/bash
R --slave -e "?$1"
After installing that in my ~/bin directory (or however you install it in your PATH), it's easy:
rdoc function
If you want to look at documentation of a function from a particular package, prepend the library name followed by two colons. For example, to pull up documentation of the dmrFinder function from the charm package:
rdoc charm::dmrFinder
