[Rd] Bug report: R.home() cause package Rcpp failed executing sourceCpp, similar bug are labeled "BUG 16660" since 2016 and here I could provide a solution that tested in my laptop.

[Tomas Kalibera]

To resolve this issue quickly on your side, I would recommend installing 
R on the C: drive which should have the short file names enabled by 
default. Then, R.home() will return a path name without a space (short 
file names do not include a space).

If you for some reason need to install R on the D: drive, then it might 
be easiest to choose installation directory without the space, such as 
"D:/R". Alternatively, you can enable short file names on your D: drive.

Re what could/should be fixed. I think code in R and packages should be 
robust against space in file names, it should properly quote the file 
names before passing to the OS. If you can debug this issue down to the 
place where quoting (e.g. via shQuote) is missing, I'd be happy to fix 
if it is in R code, please submit a bug report/patch. If it is in Rcpp 
or other package you may contribute a patch/ask the package maintainer 
to fix.

Best
Tomas
