I successfully installed caret but when loading the library I get the following error message:
library(caret)
Error: package or namespace load failed for ‘caret’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
namespace ‘generics’ 0.0.2 is already loaded, but >= 0.1.0 is required
what does 0.1.0 refer to?
I had the same issue, apparently some required dependencies for the caret package need to be updated. However installing it with DEPENDENCIES = TRUE, did not fix the problem for me.
What did work was:
Close all your .rmd files in RStudio and then click on the 'update' button in the tab with the packages:
This should update all your packages including the ones caret needs be updated, to work with their latest version.
I solved the problem by uninstalling the caret package, restarting R and installing the package from zip file.
It is asking about the latest version of generics package. It could be solved either by manually installing some earlier version of package caret or updating the base r packages.
update.packages()
If it asks for permission then use sudo
First use this:
install.packages('hardhat')
library(hardhat)
install.packages('ipred')
library(ipred)
then,you can use library(caret).

I have written my code a-2 months ago and i try to reuse it, but the installation of packages fails and i become this warning:
install.packages("devtools")
library("devtools")
> library("devtools")
Loading required package: usethis
Error: package or namespace load failed for ‘usethis’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
namespace ‘cli’ 3.3.0 is already loaded, but >= 3.4.0 is required
Error: package ‘usethis’ could not be loaded
Although i reinstalled RStudio and R, tried to upadte all packages and install all their dependencies etc, it fails to install the updates/packages. Do you have any idea? Thank you in advance.
first you need to check from bottom right (Packages) and search for devtools if you found check if installed or not, also you can write ?devtools to see if help page show up for Package development tools for R, if you want to use the package you can write devtools:: and follow it with the name of function.
strong textI keep encountering problems with installing tidyverse package, which preventing me from implementing many text processing tasks. The problem is the same as those mentioned in many previous threads since 2017 in that when I enter library(tidyverse) or try to open other related packages, they always say it requires 0.2.1 version of vctrs. I have tried using remote download or download other temporary versions but to avail. Could someone help me on this?
I'm using the latest version of R (version 3.6.1), running on Rstudio 1.2.5033. I also updated my vctrs package.
install.packages("tidyverse")
devtools::install_github("tidyverse/tidyverse")
library(tidyverse)
Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):

This has already been answered above, and I am leaving my notes for other "beginners" that may have run into the same thing. I encountered this issue after installing tidymodels (have since removed).
Had issue with rlang first: namespace ‘rlang’ 0.4.7 is already loaded, but >= 0.4.10 is required
remove.packages("rlang"), install.packages("rlang")
Then had issue with vctrs: namespace ‘vctrs’ 0.3.2 is already loaded, but >= 0.3.6 is required
does not respond to the remove/install process.
Shut down R, manually delete the vctrs directory from lib, per Edward's message above. Will be somewhere like: C:\Users\Chris\Documents\R\win-library\3.6\vctrs
Start RStudio. install.packages("vctrs")
After this, I could load tidyverse again.
It´s important to check for packages updates. It´s in tool menu->check for package updates->choose the packages. I had the same problem with other package "drc" and it gave me the same error with old version of "vctr".
You've probably got more than one instance of R running with those tidyverse packages loaded. Not sure about other operating systems, but on Windows, if these packages are being used, then those DLL files will be in use and you cannot delete them, which is what the install.packages() function will try to do.
So, just close all but one instance of R, maybe restart the computer just to be sure, and try again.
I had the same issue:
namespace 'vctrs' 0.3.7 is already loaded, but >= 0.3.8 is required
I tried:
unloadNamespace("vctrs")
namespace 'vctrs' is imported by 'pillar' so cannot be unloaded
So then:
install.packages("pillar")
It automatically restarts R and re-installs pillar. This worked for me!
I had the same problem and I installed Rtools, which is a package management tool for R, from https://cran.r-project.org/bin/windows/Rtools/ and it worked!
I have installed ggplot2 in R but when I try to load it, R gives this ERROR message:
library(ggplot2)
Error: package or namespace load failed for ‘ggplot2’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): namespace ‘rlang’ 0.4.6 is already loaded, but >= 0.4.7 is required
What should I do?
Thanks in advance.
Install the full tidyverse package, it will load all graphics dependencies include gglot2 and its dependencies too.
install.packages("tidyverse")
As mentioned here:
https://community.rstudio.com/t/i-cant-load-ggplot2-in-my-library-in-r-version-3-4-3/6466
I am working on WINDOWS OS and I had same problems with loading ggplot2 and other libraries. I tried to install it like it was suggested in other threads, but it didn't solve the problem. I found some similar issues in other topics, and i figured out that my Rstudio console wanted to have fresh a toolchain bundle called Rtools. It can be downloaded from CRAN REP.
You have to pick appripiote version for your Rengine version. If you do not know what version of R you have, you have to simple type R.version in console, and then download proper version of Rtools. After that, i updated every libraries in Rstudio. ggplot2, tidyverse and many other are working properly from that time
I hope that it could help somebody :)

I have seen similar questions for other packages and I have tried solutions offered in other posts, such as removing the package and installing it again, clearing global environment etc, but I still get the same error.

Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘slam’
I have tried updating all packages in RStudio, to no avail. I am currently trying to run a Boosted Regression Tree for data I have. If I proceed with the above error, I end up getting:
Error: could not find function "ecospat.boyce"
Any help would be highly appreciated.
I was having the same error message but in my case, it was the package called latticeExtra the one missing on my computer. I tried installing that package but was not available from CRAN. Then, I looked for the tar.gz file and tried installing the package, an error message popped up saying I needed a most recent version of R. Finally, I updated my R version (from 3.5.3 to 3.6.3) and tried using the ecospat package, it worked!
