I'm using RStudio + Github and have been following the instructions here: https://happygitwithr.com/https-pat.html
It works great, except that within a couple of hours the PAT no longer works and I'm prompted to enter a username/password. I go back and generate a new PAT, and repeat. Here's the code I'm using.
> usethis::create_github_token()
• Call `gitcreds::gitcreds_set()` to register this token in the local Git credential store
It is also a great idea to store this token in any password-management software that you use
✔ Opening URL 'https://github.com/settings/tokens/new?scopes=repo,user,gist,workflow&description=DESCRIBE THE TOKEN\'S USE CASE'
> usethis::create_github_token()
• Call `gitcreds::gitcreds_set()` to register this token in the local Git credential store
It is also a great idea to store this token in any password-management software that you use
✔ Opening URL 'https://github.com/settings/tokens/new?scopes=repo,user,gist,workflow&description=DESCRIBE THE TOKEN\'S USE CASE'
> gitcreds::gitcreds_set()
? Enter password or token: <token>
-> Adding new credentials...
-> Removing credetials from cache...
-> Done.
I have also set the following:
git config --global credential.helper 'cache --timeout=10000000'
The PAT can be stored as environment variable so a key=value assignment in the ~/.Renviron file is a very possible solution.
Another is to explicitly inject it from ~/.Rprofile via Sys.setenv(key="value").
You can test either in any R session via
> v <- Sys.getenv()
> "GITHUB_PAT" %in% names(v)
[1] TRUE

When you create a PAT (in the GitHub UI) you can give it explicit lifetimes. I happily re-used on this week which I created a year ago for a particular scripting need.

When running R CMD check I get the following note:
checking for future file timestamps ... NOTE
unable to verify current time
I have seen this discussed here, but I am not sure which files it is checking for timestamps, so I'm not sure which files I should look at. This happens locally on my windows and remotely on different systems (using github actions).
Take a look at https://svn.r-project.org/R/trunk/src/library/tools/R/check.R
The check command relies on an external web resource:
now <- tryCatch({
foo <- suppressWarnings(readLines("http://worldclockapi.com/api/json/utc/now",
warn = FALSE))
This resource http://worldclockapi.com/ is currently not available.
Hence the following happens (see same package source):
if (is.na(now)) {
any <- TRUE
noteLog(Log, "unable to verify current time")
See also references:
https://community.rstudio.com/t/r-devel-r-cmd-check-failing-because-of-time-unable-to-verify-current-time/25589
So, unfortunately this requires a fix in the check function by the R development team ... or the web-resource coming online again.
To add to qasta's answer, you can silence this check by setting the _R_CHECK_SYSTEM_CLOCK_ environment variable to zero e.g Sys.setenv('_R_CHECK_SYSTEM_CLOCK_' = 0)
To silence this in a persistent manner, you can set this environment variable on R startup. One way to do so is through the .Renviron file, in the following manner:
install.packages("usethis") (If not installed already)
usethis::edit_r_environ()
Add _R_CHECK_SYSTEM_CLOCK_=0 to the file
Save, close file, restart R
I'm trying to use git from within RStudio to send my project to github. I'm using HTTPS authentication and with this, I can create repository(locally and remotely) and commit changes. However, when i check my github, only repository is created but my R files not found.
This is what i tried
library(usethis)
edit_r_environ()
GITHUB_PAT = 'xxxx...X' #restart R session
use_github(protocol = 'https', auth_token = Sys.getenv("GITHUB_PAT")) #created a protocol with Access
token generated from PAT
#Are title and description ok?
1: No way
2: Definitely
3: Absolutely not
#i typed 2 and entered
After the above code, repository was created on github but my R codes are missing. I wanted to use push in git connection but the push/pull was greyed out.
Am aware of other approaches but help using the usethis package in R would be apreciated
I am trying to install a sample package from my github repo:
https://github.com/jpmarindiaz/samplepkg
I can install it when the repo is public using any of the following commands through the R interpreter:
install_github("jpmarindiaz/rdali")
install_github("rdali",user="jpmarindiaz")
install_github("jpmarindiaz/rdali",auth_user="jpmarindiaz")
But when the git repository is private I get an Error:
Installing github repo samplepkg/master from jpmarindiaz
Downloading samplepkg.zip from
https://github.com/jpmarindiaz/samplepkg/archive/master.zip
Error: client error: (406) Not Acceptable
I haven't figured out how the authentication works when the repo is private, any hints?
Have you tried setting a personal access token (PAT) and passing it along as the value of the auth_token argument of install_github()?
See ?install_github way down at the bottom (Package devtools version 1.5.0.99).
Create an access token in:
https://github.com/settings/tokens
Check the branch name and pass it to ref
devtools::install_github("user/repo"
,ref="main"
,auth_token = "tokenstring"
)
A more modern solution to this problem is to set your credentials in R using the usethis and credentials packages.
#set config
usethis::use_git_config(user.name = "YourName", user.email = "your#mail.com")
#Go to github page to generate token
usethis::create_github_token()
#paste your PAT into pop-up that follows...
credentials::set_github_pat()
#now remotes::install_github() will work
remotes::install_github("username/privaterepo")

Is there some way to source an R script from the web?
e.g. source('http://github.com/project/R/file.r')
Reason: I currently have a project that I'd like to make available for use but isn't ready to be packaged yet. So it would be great to give people a single file to source from the web (that will then source all the individual function files).
On closer inspection, the problem appears to be https. How would I source this file?
https://raw.github.com/hadley/stringr/master/R/c.r
You can use the source_url in the devtools library
library(devtools)
source_url('https://raw.github.com/hadley/stringr/master/R/c.r')
This is a wrapper for the RCurl method by #ROLO
Yes you can, try running this R tutorial:
source("http://www.mayin.org/ajayshah/KB/R/tutorial.R")
(Source)
Https is only supported on Windows, when R is started with the --internet2 command line option (see FAQ):
> source("https://pastebin.com/raw.php?i=zdBYP5Ft")
> test()
[1] "passed"
Without this option, or on linux, you will get the error "unsupported URL scheme". In that case resort to the solution suggested by #ulidtko, or:
Here is a way to do it using RCurl, which also supports https:
library(RCurl)
eval( expr =
parse( text = getURL("http://www.mayin.org/ajayshah/KB/R/tutorial.R",
ssl.verifypeer=FALSE) ))
(You can remove the ssl.verifypeer if the ssl certificate is valid)
Yes, it is possible and worked for me right away.
R> source("http://pastebin.com/raw.php?i=zdBYP5Ft")
R> test()
[1] "passed"
Regarding the HTTPS part, it isn't supported by internal R code. However, R can use external utilities like wget or curl to fetch https:// URLs. One will need to write additional code to be able to source the files.
Sample code might be like this:
wget.and.source <- function(url) {
fname <- tempfile()
download.file(url, fname, method="wget")
source(fname)
unlink(fname)
}
There is a Windows-only solution too: start R with --internet2 commandline option. This will switch all the internet code in R to using IE, and consequently HTTPS will work.
Windows:
If Internet Explorer is configured to access the web using your organization's proxy, you can direct R to use these IE settings instead of the default R settings. This change can be made once by the following steps:
Save your work and close all R sessions you may have open.
Edit the following file. (Note: Your exact path will differ based on your R installation)
C:\Program Files\R\R-2.15.2\etc\Rprofile.site
Open this "Rprofile.site" file in Notepad and add the following line on a new line at the end of the file:
utils::setInternet2(TRUE)
You may now open a new R session and retry your "source" command.
Linux alikes:
Use G. Grothendieck's suggestion. At the command prompt within R type:
source(pipe(paste("wget -O -", "https://github.com/enter/your/url/here.r")))
You may get an error saying:
cannot verify certificate - - - - Self-signed certificate encountered.
At this point it is up to you to decide whether you trust the person issuing the self-signed certificate and proceed or to stop.
If you decide to proceed, you can connect insecurely as follows:
source(pipe(paste("wget -O -", "https://github.com/enter/your/url.r", "--no-check-certificate")))
For more details, see the following:
See section 2.19
CRAN R Documentation 2.19
wget documentation section 2.8 for "no-check-certificate"

The methods here were giving me the following error from github:
OpenSSL: error:14077458:SSL routines:SSL23_GET_SERVER_HELLO:reason(1112)
I used the following function to resolve it:
github.download = function(url) {
fname <- tempfile()
system(sprintf("curl -3 %s > %s", url, fname))
return(fname)
}
source(github.download('http://github.com/project/R/file.r'))
