Hi e eeyore,
Here is one way:
fx <- function(x, m) x*2/(3*m)*(1-x/(3*m))
foo <- function(m) integrate(fx, m = m, lower = 0, upper = 3*m)$value
foo(3)
# 3
foo(2)
# 2
And remember:
#install.packages('fortunes')
require(fortunes)
fortune('Yoda')
Evelyn Hall: I would like to know how (if) I can ex
I know that is not Mhatematica, my question is only is it possible, it
seams its not..
Sorry if I did not get it, I can interprete different your answer, not
intentionally..
Thanks for your answer and patience.

Check how wolfram work with same integral, I dont need to replace anything..

You almost did write it in R. You just left the "m"
This is not homework, I calculate some expectations and to finish that I
must solve integral like this one..
Upper bound have some unknown parameter, but I dont know how to write it in
R.
Do I must define m like symbol, or something else, just need help with that.
I know how this work in MatLab, b

The problem is in upper bound, it depends on parameter m.
