Hi,
yesterday I installed the current R-devel and now I get
the following warning message for program codes which made no
problems under version R-1.2.3:
Example:
R> read.table("test.dat")
Warning message:
incomplete final line in: readLines(con, n, ok)
where `test.dat' looks like
peters at artemis:~ > cat test.dat
1 2 3peters at artemis:~ >
i.e. without a newline at the end.
The warning can be suppressed if the last line in "test.dat" ends with
"\n". Is there a reason why "test.dat" should end with
"\n" or is this a
bug in R-devel?

Not having one could be a sign that the file was corrupted, hence the warning. Other utilities will also give warnings, e.g. vim will display the file with "[noeol]", other vi-s will complain and fix the last line. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
