Can´t load tidyverse

[Mautt24]

Hi,

I am not able to load the package tidyverse (it is installed, but not loaded). The following message appears when trying to load it:

> library(tidyverse)
Error: package or namespace load failed for 'tidyverse' in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
 there is no package called 'Rcpp'

So it seems that I need to install the package Rcpp. After I install it the following message appears:

> install.packages("Rcpp")

  There is a binary version available but the source version is later:
     binary  source needs_compilation
Rcpp  1.0.4 1.0.4.6              TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) yes
installing the source package 'Rcpp'

The downloaded source packages are in
	'/private/var/folders/1d/94sf45nn14g6b5ldhdf5tm3r0000gn/T/Rtmp3liROx/downloaded_packages'

When I check if the package was installed with these code:

my_packages <- library()$results[,1]
my_packages=="Rcpp"

There is no TRUE, so the package wasn´t install.

Can someone please help me? Been dealing with this problem 3 days already, and can´t continue with a course I´m taking.

Thanks!

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) yes

The easiest solution would be to answer "no" to this question, you would get a precompiled binary version that is a little older but much easier to install.
If you need to install the latest version from source, then you need to install xcode in your system (not in R) and the recommended development tools for MacOS systems.

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …
