Hi,
I have some text files that do not have trailing \n on the last
(incomplete) line; how do I read in the last line?
e.g. here is a test case: [linux + R version 2.6.1 (2007-11-26) ]
z <- gzfile("short.gz", open="w")
cat("7\n5\n3", file=z)
close(z)
z <- gzfile('short.gz')
readLines(z)
[1] "7" "5"
readLines would indicate that for blocking connections (which I assume
this is), the last line (containing 3) would be read in, and a warning
would be generated. I get the desired behaviour if I use a file() on
a file that is not compressed:
y <- file("short", open="w")
cat("7\n5\n3", file=y)
close(y)
y <- file('short')
readLines(y)
[1] "7" "5" "3"
Warning message:
In readLines(y) : incomplete final line found on 'short'
What am I missing?
Thanks, Stephen
