Is it possible to read files from a UNC-specified directory in R? I'd like to do it without using any packages beyond the base installation.
UNC names work fine, you just have to escape them correctly. This works for me:
read.csv('\\\\COMPUTER\\Directory\\file.txt')
adding to nograpes answer ... you can avoid the escaping ugliness by using forward slashes ... this works as well
read.csv('//COMPUTER/Directory/file.txt')
a slightly more cross-platform approach
# the two '' are required to represent the two leading slashes of the UNC path
read.csv(file.path('', '', 'COMPUTER', 'Directory' 'file.txt'))
