r - Using system with windows -


i have following string i'm trying pass system on win 7 machine. should creating .git directory in repo using system not (though similar approach work on linux box windows specific problem).

system( "cd c:/users/trinker/desktop/foo2 && \"c:\\program files (x86)\\git\\bin\\git.exe\" init" )

c:/users/trinker/desktop/foo2 location of repo. c:\\program files (x86)\\git\\bin\\git.exe location of git on system.

when run above nothing happens. no message, nadda. run cat on string , paste directly command line runs, gives following message , creates .git in appropriate place.

so running...

cat("cd c:/users/trinker/desktop/foo2 && \"c:\\program files (x86)\\git\\bin\\git.exe\" init")

pasting command line...

cd c:/users/trinker/desktop/foo2 && "c:\program files (x86)\git\bin\git.exe" init

gives...

initialized empty git repository in c:/users/trinker/desktop/foo2/.git/

...which good

so can outside of r same string not within r. need first string use system make run if though cat , pasted command line? answer great i'd know what's going on here can address similar circumstances in future accessing windows command line system.

give try - @ least me using system("cd blah blah && blah blah", intern = true) gave error in system(cmd, intern = t) : 'cd' not found using cd out - luckily working directory used can change working directory in r instead of in system call.

wd <- getwd() setwd("c:/users/trinker/desktop/foo2") cmd <- '"c:/program files (x86)/git/bin/git.exe" init' system(cmd, intern = t) setwd(wd)

the intern parameter isn't necessary can debugging.

i'm thankful typically run on linux ;)
