About '..', see if the following sequence of instructions can help.
Subdirectories '~/tmp' and '~/snap' exist on my PC, change to
'~/analysis/scripts' or to what makes sense on yours.
od <- getwd() # save this for later
list.files('../snap') # goes up one level and
# executes a SO/files related command
curr <- getwd()
basename(curr) # these two instructions are meant to show that
dirname(curr) # you don't need to know how many levels you have
# to go up, you can parse 'curr' if basename and
# dirname are not enough
setwd(od) # back to where I was
Hope this helps,
