Rtools35 gcc.exe missing in windows - r

Just installed Rtools35 with Admin rights and all options checked:
and running:
> Sys.which("ls.exe")
ls.exe
"C:\\Rtools\\bin\\ls.exe"
> Sys.which("gcc.exe")
gcc.exe
""
I also manually looked inside 'C:\Rtools\bin\' and gcc.exe is missing. Can't build packages.
Attempt using installr.
library(installr)
> install.rtools()
Loading required namespace: devtools
No need to install Rtools - You've got the relevant version of Rtools installed
Also, uninstalled, restarted and reinstalled just to be sure.

Is memory.limit() broken?

I run memory.limit() on my 48G Windows 10 machine and it returned 1.759219e+13. This is head scratching. I am using R 3.6.1.
Is memory.limit() broken? Any other way to obtain memory limit?
Here is my sessionInfo():

This is an issue with RStudio (hopefully fixed in the next update). It works well in RGui.
You can use disk.frame::df_ram_size() instead. It works on Windows 10 with RStudio and R 3.6.1.
You can install disk.frame using install.packages("disk.frame")

R: warning/error when calling normalizePath(...) or adding to .libPath(...)

I have a shared computer. If I login with windows userA, I can run the following:
normalizePath("//mydrive/my/path", "/")
and it returns:
"\\\\mydrive/my/path"
However if login to windows under userB, I get this message:
Warning message: In normalizePath(path.expand(path), winslash,
mustWork) : path[1]="//mydrive/my/path": An unexpected network
error occurred
What does it mean? This has important consequences, as it prevents to add "//mydrive/my/path" to the .libPaths() when running under userB, e.g .libPaths(new="//mydrive/my/path"), it prints the same warning, then as soon as I try to use a package that is in this lib location, it show the ERROR:
Error in normalizePath(path.expand(path), winslash, mustWork) :
path[1]="//mydrive/my/path": An unexpected network error occurred
Here are the details of my session under userA:

igraph R - 'error in base'

I've recently updated my Windows machine and reinstalled R3.4.0 (64bit) and igraph 1.0.1. I've previously used igraph in combination with FCMapper and it's worked perfectly.
On the new machine I keep getting the following error, even with code that previously worked without a hitch:
Error in base::.Call("R_igraph_check_finally_stack", PACKAGE =
"igraph") : "R_igraph_check_finally_stack" not available for
.Call() for package "igraph"
Error in base::.Call(.NAME, ...) : "R_igraph_finalizer" not
available for .Call() for package "igraph"
I've had a google and the previous responses indicate that it's a NAMESPACE error in the current version of the package. Any help would be appreciated!

Simple R Language summary function is giving "Object Not Found" error

I'm trying to read a stata file in R Studio using the following code:

However, the console is displaying the following error:

Can anyone please help me out that why is this happening even though I'm just copying and pasting simple example from this link:

Error attempting to write history

Before a project is open, R rapidly throws this error:
Surprisingly, I do not find anything related to this error with google. Even if, apparently, it does not cause problems to the working session, I am interested in its effects, to avoid possible future inconveniences.
