hello,everyone. I have one question: example 1 > x=numeric(0) > y=5 > print(x+y) numeric(0) example 2 > x=numeric(1) > y=5 > print(x+y) [1] 5
why the print(x+y) is numeric(0) at the first example, but the result is 0 at the second example? __________________________________________________ �Ż����G���䣭�й���һ���������ʼ�ɧ�ų������� ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
