Interacting with the file system

I find this very useful knowledge when using notebooks (just note, in the IPython notebooks this stuff is shell commands prefixed with a "!")
Some basics you are most likely familiar with are as follows (not an exhaustive list!) - for a more thorough list go here



In [ ]:

    
getwd()



In [ ]:

    
R.home()



In [ ]:

    
R.version.string



In [ ]:

    
# setwd()



In [ ]:

    
dir()



In [ ]:

    
dir(pattern = "ipynb")



In [ ]:

    
nbs <- dir(pattern = "ipynb")
print(nbs[1])
file.info(nbs[1])$isdir
file.exists(nbs[1])



In [ ]:

    
p <- file.path(getwd(), 'newfile')
print(p)
basename(p)
dirname(p)
