r - setwd() does not work in Rmd-file in Rstudio -


setwd() not work in rmd-file.

this different issue question: in rstudio/rmarkdown, how setwd?, because issue can't set wd in one chunk, while linked question ask ways set wd globally all chunks, while having no problems setting wd one chunk.

a call setwd() works .r-file, not work when sent console .rmd-file.

the picture below shows 2 instances of call setwd(), using same directory each time. first time works, second time not work, can seen fact getwd() not show directory specified in setwd().

in base rgui works:

sometimes (but not everytime) when run code following warnings:
