Hello,

I am using R 3.6.3

And I am trying to install BiocManager via:

if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install(version = "3.10")

> if (!requireNamespace("BiocManager", quietly = TRUE))
+     install.packages("BiocManager")
> BiocManager::install(version = "3.10")
Bioconductor version 3.10 (BiocManager 1.30.10), R 3.6.3 (2020-02-29)
Installation path not writeable, unable to update packages: boot, class,
  KernSmooth, lattice, MASS, nlme, nnet, spatial, survival

Can you please advise, Ana

indicates that some packages have been installed under a different account, usually an 'administrator' account. These are so-called 'recommended' packages; you can ignore the warning, or you can re-install R but do not use an administrator account to do so.

you required admin permission to install this
