how can we know what does it mean?
Plotmath expressions are rather tricky, especially if you do not use them often. You need some experimenting.
Cheers

Changing ggplot2 legend key/title to custom text
Hi all,
ok I have this issue:
I want to change my graphs legends to custom text, often requiring the use of superscripts/subscripts
I tried to use this instruction I found on stack overflow:
labs(x = "R(Ohm)", y= "CDF", aesthetic= " Content (%)" )
but it wont' seem to work.
Also tried bquote for super/ subscripts
xlab(bquote(~x~/(~x~ + ~MO[2]~)*

Optim function returning always initial value for parameter to be optimized
Hello,
I'm trying to fminimize the following problem:
You have a data frame with 2 columns.
data.input= data.frame(state1 = (1:500), state2 = (201:700) )
with data that partially overlap in terms of values.
I want to minimize the assessment error of each state by using this function:
err.th.scalar <- function(threshold, data){
state1 <- data$state1
state2 <- data$state2

Bi variate minimization problem
Dear all,
I'm working on the following problem:
Assume two datasets: Y, Y that represent the same physical quantity Q. Dataset X contains values of Q after an event A while dataset Y contains values of Q after an event B.
In R X, Y are vectors of the same length, containing effectivelly a number of observations of Q in each state.
Q is a continous variable.
Now, the two datasets should
