I have
mydata$var
#this is ONE group of patients
And I would like to get
median and ICR of mydata$var.
How can I get this?
With summary (mydata$var)!
Ok!
And now I would like to get THE SAME, but for TWO group: male and
female (which are contained in the group mydata$var)
How can I get this?
First I need to split mydata$var by mydata$sex, and then take:
summary (for male)
and
summary (for female)
That's all I want
Bert,
ave(mydata$var, madata$sex, FUN=median)
gives me:
[1] 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6 5.6
5.6 5.6 5.6 5.6
[21] 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0 6.0
6.0 6.0 6.0 6.0
What is it?
It is an endless(???) repetition of the median.
Moreover, there is no ICR.
Jeff,
your constructions are too complicated for me

P.S. Such simple thing and so difficult?! (I begin think about the Excel.)
