Proportions again
Andrew Robinson <andrewr at uidaho.edu> writes:
table(sex)/length(sex)
or, as is the intended usage:
prop.table(table(sex))
sex
1 2
0.375 0.625
I asked before and it was great, cause as a beginner I learned a lot. But,
if I have this in R (1 and 2 are codes for sex):
sex<-c(1,2,2,1,1,2,2,2) sex
[1] 1 2 2 1 1 2 2 2 I?d like to obtain the proportion according to sex.So I type:
prop.table(sex)
[1] 0.07692308 0.15384615 0.15384615 0.07692308 0.07692308 0.15384615
0.15384615 [8] 0.15384615
The result is OK, but I expected to see a simple frequency table or
something like that:
1 0.375
2 0.625
1.0
How can I get this ?
