when pressing compile notebook button in rstudio, following error:

error in file(con, "r") : cannot open connection in addition: warning message: in file(con, "r") :   cannot open file 'c:/dropbox/teaching/tau/2016 - b/׳׳‘׳•׳ ׳׳¡׳˜׳˜׳™׳¡׳˜׳™׳§׳” - ׳׳¡׳˜׳˜׳™׳¡׳˜׳™׳§׳׳™׳/׳×׳™׳¨׳’׳•׳׳™׳/stat_intro_2016/intro_stat.r': no such file or directory

this actual path:

getwd() [1] "c:/dropbox/teaching/tau/2016 - b/מבוא לסטטיסטיקה - לסטטיסטיקאים/תירגולים/stat_intro_2016"
