Can't install caret package in R

I have tried multiple ways to install the caret package in R. The error message that I receive is as follows:

Error: package or namespace load failed for ‘caret’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘dimRed’

When I try to install dimRed, I get the following message:

Installing package into ‘C:/Users/Thomas/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)
Warning in install.packages :
  dependency ‘Biobase’ is not available

  There is a binary version available but the source version is later:
   binary source needs_compilation
dimRed  0.1.0  0.2.1             FALSE

installing the source package ‘dimRed’

trying URL 'https://cran.rstudio.com/src/contrib/dimRed_0.2.1.tar.gz'
Content type 'application/x-gzip' length 363025 bytes (354 KB)

The downloaded source packages are in ‘C:\Users\Thomas\AppData\Local\Temp\RtmpqKhsKn\downloaded_packages’

Per previous posts, I have updated RStudio. I have attempted an install from install_url.

Any suggestions are welcome.

Warning ... 

install.packages("BiocManager")

This only works if your R version is >= 3.5.0

for info I've the same problem under a Centos and a Windows. issue solved on the windows with 3.5.1 R version. Not yet solved on the centOS (3.4.2)

I was able to figure this out. Simply typing install.packages won't work. In order to install Biobase, you have to run the following code in R console:

if (!requireNamespace("BiocManager", quietly = TRUE))
  install.packages("BiocManager")
BiocManager::install("Biobase", version = "3.8")

More info: https://bioconductor.org/packages/release/bioc/html/Biobase.html

Once this step is done, I installed caret again using

install.packages("caret",dependencies = T)

And then it worked.
