Total Beginner stuck on installing tidyverse (error code +++)

[Tigerbach]

Hello friends! I'm a total R beginner and learning to analyze data from clinical trials. I've fallen at the first hurdle: trying to install tidyverse. I can't seem to interpret the error code and figure out what I'm doing wrong. Any guidance much appreciated:

Try to install packages the Rcpp binary

[ADernild]

Not sure if this is the problem, but are you running R as administrator/superuser?

[Tigerbach]

Forgive me, I'm such a noob that I don't actually know what that means. Is there a line of code I can run? And thanks for your response!

[Tigerbach]

I don't think so... I'm just using R Studio on my personal macbook air. And thanks also for your reply!

[nirgrahamuk]

I'm recommending you try

install.packages(pkgs = "Rcpp",type="binary")

please write back if there are further issues.

[Tigerbach]

Thanks very much Nir. I ran that line of code first and then tried to download and load tidyverse but still no joy (screenshot of code below). Do you have any further suggestions? Again, really appreciate all your help.

[Tigerbach]

Apologies not sure if I did direct reply correctly, have posted below. Thank you!

It seems to be an issue with the CRAN version of Rcpp for MacOS systems, can you try installing this way?

install.packages("Rcpp", repos="https://rcppcore.github.io/drat")

This is the GitHub issue for reference

Many packages are broken on Mac with CRAN version of Rcpp -- unless 10.11 SDK is used as on CRAN

Thanks to you and everyone for all your help. I did the rather old fashioned thing of uninstalling R and R Studio, and upon re-install I'm not able to load tidyverse etc without issue. Thanks again!
