Hi. Out of curiosity, I tried to install.packages("tidyverse"). After several minutes of output, it ended on an error with dependencies (googledrive, googlesheets4, haven, httr, rvest, xml2) and the removal of the package. What to do then?

So it seems like some packages that are dependencies of tidyverse (i.e. packages that the tidyverse relies on for certain functions) didn't install correctly. What operating system are you using?

Benoit Gauthier

Ubuntu 18.04.6 LTS

Benoit Gauthier

January 13, 2022

After some googling around, I found that some (3) packages needed be installed in Ubuntu itself (libcurl4-openssl-dev, libxml2-dev, libssl-dev). The dependency verification process built into R did not take care of these installations. I'm good now.

Hi! I am having the following warning:

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

But still doing what its needed, should I be worried?

Charlie Hadley

March 21, 2022

Hi Delia. RTools is a collection of compilers and other things that are not installed by default on Windows and are occasionally required when using R. Unfortunately, it's not always clear that something isn't working because RTools is missing. So I'd recommend installing it at the beginning so it's just there. Thanks, Charlotte

Oh perfect! Thanks!

I see this error. Error in install.packages : object 'tidyverse' not found

NIKHIL RATNA

July 19, 2022

I am sorry, its a syntax error.

Charlie Hadley

July 19, 2022

Yup! Almost all functions for manipulating packages require package names in quotation marks (ie, as a string). The only exception is library(tidyverse)

NIKHIL RATNA

July 19, 2022

Do you want to install from sources the packages which need compilation?

what does that mean and what should I answer. I am going with yes for now

Charlie Hadley

July 19, 2022

Hi Nikhil,

This is a useful thread that goes into lots of detail about what installing from source means.

It's almost always okay to say "yes", provided you have the necessary tooling for installing from source. On macOS and Linux this tooling is almost always going to be correctly configured on your system. Whereas on Windows you would need to install RTools and there might be some additional configuration required.

If installing from source fails select "no" instead. If this means the code you're trying to work truly depends on installing from source you'll have errors. These can be fixed by either waiting 2 days for CRAN to update or else to investigate what's wrong with your tooling - but that can get quite complicated.

Cheers,

Charlie

After starting a new project (for my work) and the 'getting started' master for this course, I still do not have a 'scripts' window in either project. All other three windows are there: Console/Terminal, Environment/History & Files/Plots/Packages/Help. Why am I missing the Scripts window?
