Difficulty accessing package

[fior-uisge]

So, using the code you suggested in your original post, this is what happens:

> remotes::install_github("joachim-gassen/tidycovid19")
Downloading GitHub repo joachim-gassen/tidycovid19@master
These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?

1: All                              
2: CRAN packages only               
3: None                             
4: Rcpp    (1.0.4 -> 1.0.4.6) [CRAN]
5: isoband (0.2.0 -> 0.2.1  ) [CRAN]

Enter one or more numbers, or an empty line to skip updates:
1
countrycode  (NA    -> 1.1.1  ) [CRAN]
gtrendsR     (NA    -> 1.4.4  ) [CRAN]

isoband      (0.2.0 -> 0.2.1  ) [CRAN]

I then tried with devtools::install_github("joachim-gassen/tidycovid19") and got a similare response:

It was only afer theis that I tried using the drat package as it allows setting up a link to the drat repository and easy installation when running scripts where you want to update data. The syntax used was:

library(drat) addRepo("joachim-gassen") install.packages("tidycovid19") This resulted in:

Warning in install.packages :

Thank you for posting this here.

Can you let me know what you get back when you run

getOption("repos")

For me, this returns the following (standard R/RStudio install)

                       CRAN 
"https://cran.rstudio.com/" 
attr(,"RStudio")
[1] TRUE

It seems that both install_github() calls try to access a drat repo at https://joachim-gassen.github.io/drat. There is no such repo. When it shows up in your repos option try to delete it and see whether this helps.

Thanks Joachim. This was where the problem lay. I've edited the .Rprofile file to remove the drat repo
