If you have your Rprofile.site file in the default place you will need
to start whatever editor you are using in administrator mode to save
your changes. At least that is so on my PC with windows 10 with R
installed in the default directory. I use notepad++ in administrator
mode. I presume that you could do the same with rstudio.
If you think that answers are short or to the point remember that
someone is giving of his time to help you. I think that you owe
someone an apology.

Hi.
First, there should be no difference in where and how R and RStudio
locate the R startup file.
Second, if there is an .Rprofile in the working directory (i.e.
./.Rprofile), then that file with have higher priority than the file
located in ~/.Rprofile. You can use the following R calls, also on
Windows, to check if you have either of these two files:
> file <- normalizePath("./.Rprofile")
> file
> file.exist(file)
> file <- normalizePath("~/.Rprofile")
> file
> file.exist(file)
In my case, my working directory is C:/Users/hb/Documents/Projects/, I
have a ~/.Rprofile file, but not a .Rprofile in the working directory.
So, I get:
> file <- normalizePath("./.Rprofile")
> file
[1] "C:\\Users\\hb\\Documents\\Projects\\.Rprofile"
> file.exists(file)
[1] FALSE
> file <- normalizePath("~/.Rprofile")
> file
[1] "C:\\Users\\hb\\Documents\\.Rprofile"
> file.exists(file)
[1] TRUE
This tells me that my startup file that R tries to load / source
during startup is "C:\\Users\\hb\\Documents\\.Rprofile" and that's the
one I should edit.
BTW, the value of normalizePath("~/.Rprofile") and
file.path(Sys.getenv("HOME"), ".Rprofile") should point to the same
file, expect that normalizePath() makes all backward slashed on
Windows; the former is just a neater version to use:
> normalizePath("~/.Rprofile")
[1] "C:\\Users\\hb\\Documents\\.Rprofile"
> file.path(Sys.getenv("HOME"), ".Rprofile")
[1] "C:/Users/hb/Documents/.Rprofile"
> normalizePath(file.path(Sys.getenv("HOME"), ".Rprofile"))
[1] "C:\\Users\\hb\\Documents\\.Rprofile"
(all of the above reference the same file).
So, if file.exists(normalizePath("~/.Rprofile")) gives FALSE, then you
don't have that file. If you think you've edited that, then it might
be that you hit the peculiar Windows property where it hides the
filename extension from you in the Explorer. It might be that you
instead have created / edited the file:
normalizePath("~/.Rprofile.txt")
That often happens when one uses Notepad and saves the file as
.Rprofile - Notepad simply add a *.txt filename extension unless you
save it with quotation marks in the Save-As panel.
Now, if you indeed have the file:
normalizePath("~/.Rprofile")
then there is one last annoyance in R that you might have hit.
If you're last
line in that file does not have a newline, the the file will be
silently ignored by R when R start. There won't be a warning - not
even a message. That is true for all OSes. It's a "feature" that
should really be fixed, because I keep seeing it tricking beginners
and advanced R users all the times. The easiest way to check if this
is your problem, use readLines() to read in the content; readLines()
will give a warning if the last line doesn't have a new line, e.g.
> readLines(normalizePath("~/.Rprofile"))
[1] "options(prompt=\"R> \")" "set.seed(12345)"
Warning message:
In readLines(normalizePath("~/.Rprofile")) :
incomplete final line found on 'C:\Users\hb\Documents\.Rprofile'
If you don't see the warning message, you should be fine.
Finally, an easy way to setup a ~/.Rprofile startup file is to do it
from within R, e.g.
> cat('options(prompt="R> ")\n', file = "~/.Rprofile")
> cat('set.seed(12345)\n', file = "~/.Rprofile", append = TRUE)
The '\n' at the end of each string represents a newline character, so
make sure you don't forget those.
Hope this help
Henrik
