I have additional Q:
v1 is gender (M=1 and F=2)
v2 is age
I want R to calculate median only for M (1),
but my comand is not good :)
while(v1=1){median(v2,na.rm=TRUE)}
Error: unexpected '=' in "while(Q2="

Hello,
summary() removes NAs by default. You can get the same results using
median(year, na.rm=TRUE)
see ?median
HTH,

Hi,
I have dataset n1 and v1 (years).
when i ask
median(year)
[1] NA
but if i put summary of dataset n1:
summary(n1)
R produces median (together with min/max/mean....)
why it is so?
