I am using RStudio. I updated my R version from 3.6.1 to 4.0.2 and since then many packages won't work. I am getting the following messages. What can I do to fix this?
> library(EEM)
Error: package or namespace load failed for ‘EEM’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘vctrs’
> data2 <- readEEM(getwd())
Error in readEEM(getwd()) : could not find function "readEEM"
> library(readxl)
Error: package or namespace load failed for ‘readxl’ in namespaceExport(ns, exports):
