library(caret)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
object 'vI' not found
In addition: Warning message:
package ‘caret’ was built under R version 3.3.3
Error: package or namespace load failed for ‘caret’
I tried everything from re-installing R to deleting all the library folder but nothing helps.
At first, you need to install package lattice and ggplot2. Then install the caret package.
or, You can use the devtools library for installing the caret package.
install.packages("devtools")
library(devtools)
install_cran("caret")

When I attempt to open up the Tidyverse library after installing the package, the following error messages comes:
>library(tidyverse)
Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘colorspace’
In addition: Warning message:
package ‘tidyverse’ was built under R version 3.6.3
I also tried to install the package color space using
install.packages("colorspace")
Exact same error messages shows as above. Please help!
p.sp. I installed Rtools40.
You can try install.packages("scales").
You can also check for the newest version using the update button in Rstudio.
here is the code I am using:
install.packages("jaccard")
library("jaccard")
The error code I receive is:
Error: package or namespace load failed for ‘jaccard’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘qvalue’
In addition: Warning message:
package ‘jaccard’ was built under R version 3.6.3
I try to install the package qvalue and receive the error:
Warning in install.packages :
package ‘qvalue’ is not available (for R version 3.6.2)
I've also tried installing jaccard and qvalue using the code:
install.packages("jaccard", repos="http://cran.rstudio.com/", dependencies=TRUE)
install.packages("qvalue", repos="http://cran.rstudio.com/", dependencies=TRUE)
None of this seems to work and I receive the same errors.
Previously, I had used this same package with the very same data. Today, I installed couple of neural network package in R. I noticed that after installing the new package, I can no longer execute the "forecast" package. There is some package missing, which I had re-install again. And the last one, I had this warning message. Is there anyone had any idea what it was?
library(forecast)
Error: package or namespace load failed for ‘forecast’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
namespace ‘pkgconfig’ 2.0.1 is being loaded, but >= 2.0.2 is required
In addition: Warning message:
package ‘forecast’ was built under R version 3.4.4
I had try to re-install the "forecast" package but still I got some error message. Thank you so much in advance.

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
namespace ‘pkgconfig’ 2.0.1 is being loaded, but >= 2.0.2 is required
This is telling you that you have to update this package dependency, try installing it first with
install.packages("pkgconfig")
If everything goes well, then you can try to install ggplot2 again, but this time try with this command
install.packages("ggplot2", dependencies = TRUE)
I tried:
library(caret)
then I got the error:
Loading required package: ggplot2
Error: package or namespace load failed for ‘ggplot2’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
namespace ‘rlang’ 0.3.0.1 is already loaded, but >= 0.3.1 is required
Error: package ‘ggplot2’ could not be loaded
In addition: Warning message:
package ‘ggplot2’ was built under R version 3.5.3
so I tried updating the ggplot2 using:
install.package("ggplot")
even after that I am getting the same error. my caret package is also updated.
I think you can try two things. One is updating your R version (and Rstudio version?). The other can be updating ggplot2 with dependencies:
install.packages('ggplot2', dependencies = TRUE)
I get the following error when I try to load ggplot2. I tried to uninstall scales and reinstall it but for some reason R can't find the package when I want to remove the package...
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace ‘scales’ 0.2.5 is already loaded, but >= 0.3.0 is required
In addition: Warning message:
package ‘ggplot2’ was built under R version 3.2.3
Error: package or namespace load failed for ‘ggplot2’
I had the same problem, I just install again ggplot2 and everything worked again. It installed also scales 0.4.2, so it solved the problem by itself.
