Here is the bug, which R.home may generate a path contains a whitespace.
this will cause Rcpp failed executing sourceCpp
> sourceCpp("b:/2018-12-14/src/18020/MCMC.cpp")
Error in system(cmd, intern = !showOutput) : 'D:/Program' not found
Error in system(cmd, ignore.stderr = TRUE, intern = TRUE) :
'D:/Program' not found
Code is tested in both R 3.5.1 and Microsoft R Open 3.5.1.
I find a temp solution, is to copy such words into Rprofile:
unlockBinding("R.home", baseenv())
utils::assignInNamespace("R.home",function (component = "home")
{
rh <- .Internal(R.home())
paste0('"',switch(component, home = rh, bin = if (.Platform$OS.type ==
"windows" && nzchar(p <- .Platform$r_arch)) file.path(rh,
component, p) else file.path(rh, component), share = if (nzchar(p <-
Sys.getenv("R_SHARE_DIR"))) p else file.path(rh,
component), doc = if (nzchar(p <- Sys.getenv("R_DOC_DIR"))) p else
file.path(rh,
component), include = if (nzchar(p <- Sys.getenv("R_INCLUDE_DIR"))) p
else file.path(rh,
component), modules = if (nzchar(p <- .Platform$r_arch)) file.path(rh,
component, p) else file.path(rh, component), file.path(rh,
component)),'"')
}, ns="base", envir=baseenv())
lockBinding("R.home", baseenv())
Actually, calling "D:/Program Files/R/R Open/bin/x64"/R is same to calling
"D:/Program Files/R/R Open/bin/x64/R"
it shows that we could use quote to quote the whitespaces.
(although the code seems a little bit ugly)
