executing file contents as commands under R from Linux terminal - r

Question

I've written a text file containing script for R. I've gotten it to run under Windows from a .bat file running a .txt file under R with CMD BATCH.
I'm trying to replicate that (minus the clickability) in the Terminal
I've changed the permissions for program execution, I've set the file to have the shebang, and have tried rewriting for it a few different programmes such as
#!/usr/bin/R
library(rvest)
library(plyr)
which returns an error "Syntax error near unexpected symbol 'rvest'
and
#!/home/robert/Téléchargements/R-3.2.3/src/unix/Rscript.c
library(rvest)
library(plyr)
which also returns an error "Syntax error near unexpected symbol 'rvest'
Separately, on both of these I changed the file extension from nothing to .R
In one case it gave the same error, in the other it started a session of R but didn't execute the commands.
I realise it's a messy question, but I'm having difficulty getting these ducks in a row.

Answer 1

Ultimately, this was what worked:
R < /home/robert/R/scraper1.R --no-save
But here's the rest of my answer in case that doesn't work for someone else:
I'm not sure if you've seen any of these, but here's some stuff to try:
Dupe?
The top answer from a very similar post: I'm going to assume you googled your question before posting it, so I'm sure you've already seen this, but it's not referenced in your question, so here it is [Source]:
Content of script.r:
#!/usr/bin/Rscript
cat("Hello")
Invocation from command line:
./script.r
?Rscript
?Rscript allows you to run R scripts in a Unix-esque system [Source]:
## example #! script for a Unix-alike
#! /path/to/Rscript --vanilla --default-packages=utils
args <- commandArgs(TRUE)
res <- try(install.packages(args))
if(inherits(res, "try-error")) q(status=1) else q()
Batch
Here's something from an old R mail pipe [Source]:
Place the line: R --vanilla < foo.txt foo.results into a file named foo.batch. No other text should be in the file.
Make this file executable via chmod 755 foo.batch
At the command line try at -f foo.batch now or perhaps, batch -f foo.batch.
If this does not work, ask your system administrator how to set up a batch process.
The advantage of the batch process is 1. you need not be logged in, 2.
your job will take a lower priority than interactive jobs.
R -e
Loading two libraries and running an R command [Source]
R -e 'library("rmarkdown");library("knitr");rmarkdown::render("NormalDevconJuly.Rmd")'
R -e 'library("markdown");rpubsUpload("normalDev","NormalDevconJuly.html")'
