rstudio - R system2 trouble invoking R script on windows -


i use rodbc connect microsoft access databases , can in 32-bit r because 32 bit ms office loaded on windows 7 pc.

after extracting data ms access database in 32-bit r, want manipulate , analyse in 64-bit r. in addition trying write script others may need use , simplify things invoking 32-bit r inside rstudio (which have set use 64-bit r, version 3.1.2).

i found this post seemed looking , attempted run suggested code. however, gives me fatal error indicating working directory not exist, though have been working directory within 64 bit r , 32 bit r , without rstudio , have never had problems:

> system2("c:\\users\\joe.bloggs\\documents\\r\\r-3.1.2\\bin\\i386\\rscript.exe", normalizepath("my script.r", winslash = "\\", mustwork = true), invisible=false) fatal error: cannot open file 'h:\03.': no such file or directory  warning message: running command '"c:\users\joe.bloggs\documents\r\r-3.1.2\bin\i386\rscript.exe" h:\03. b project\my script.r' had status 2

note have installed r , rstudio in "documents" folder in c drive since don't have administrative rights.

also, r script on network drive (h).

i have tried copying r script want run default working directory of 32-bit r on c drive , explicitly stating filepath without using normalizepath (as assume command expands current working directory in 64-bit r), gives same error above.

further, if try invoke 32-bit r, warning:

> system2("c:\\users\\joe.bloggs\\documents\\r\\r-3.1.2\\bin\\i386\\rscript.exe", invisible=false) usage: /path/to/rscript [--options] [-e expr [-e expr2 ...] | file] [args]  --options accepted   --help              print usage , exit   --version           print version , exit   --verbose           print information on progress   --default-packages=list                       'list' comma-separated set                         of package names, or 'null' or options r, in addition --slave --no-restore, such   --save              save workspace @ end of session   --no-environ        don't read site , user environment files   --no-site-file      don't read site-wide rprofile   --no-init-file      don't read user r profile   --restore           restore saved objects @ startup   --vanilla           combine --no-save, --no-restore, --no-site-file                         --no-init-file , --no-environ  'file' may contain spaces not shell metacharacters expressions (one or more '-e <expr>') may used *instead* of 'file' see  ?rscript  within r warning message: running command '"c:\users\joe.bloggs\documents\r\r-3.1.2\bin\i386\rscript.exe"' had status 1

any insights doing wrong appreciated; tried using single forward slashes instead of double slashes in both file paths no avail; still got same error.

how can system2 locate r script , run in 32-bit r?

also there resource explains status numbers in warnings mean?

many help.

i've been trying same thing (call 32 bit r 64bit rstudio rodbc) , asked similar question here. used different approach , did: 

system(paste0(sys.getenv("r_home"), "/bin/i386/rscript.exe h:\\path\\to\\file.r"), wait = false, invisible = false)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
