Hi,
Using the full path specification, as you have done in your second example, is
a good idea. Have you tried forward slashes? If I am reading the docs
correctly you should be able to use either forward or back slashes. I haven't
used R in Windows for ages, but my memory is that switching to forward slashes
skirted any troublesome issues. Try this...
filename <- "C:/Program Files/R/R-3.2.3/Appendix/DATA1.txt"
if (file.exists(filename)){
X <- scan(file = filename, what = double())
} else {
cat('file not found\n')
}
Here's the doc page...
