Just upgraded R to 4.0.4, RTools to 4, and RStudio to 1.4. Now library(tidyverse) fails. As you can imagine, living without tidyverse is not an option.
In the course of trying to fix this, I uninstalled previous versions of R, RTools, and RStudio and did a fresh reinstall. (I am on Windows 10.) The error message I get begins
> library(tidyverse)
Error: package or namespace load failed for ‘tidyverse’ in namespaceExport(ns, exports):
undefined exports: augment_columns, bootstrap, confint_tidy, finish_glance, fix_data_frame, tidy_irlba
In addition: Warning message:
S3 methods ‘augment.NULL’, ‘augment.Mclust’, ‘augment.betamfx’, ‘augment.betareg’, ‘augment.clm’,
Any suggestions gratefully received.
