[R] expression in xlab for a plot

[arun]

HI,
Another way would be to use ?substitute()
hist(runif(1000,0,100),xlab=substitute(expression(AUC[low - high]~ (xyz)),list(low=low,high=high)),ylab="Frequency")
A.K.

Dear All,

Happy new year!

wonder if you could help with the following:

we have:

hist(runif(1000,0,100),xlab=expression(AUC[0 - 24]~ (xyz)),ylab="Frequency")


the plan is to have part of the xlab expression change dynamically, specifically the values of 0 and 24 should be able to update 'automatically" , based on vectors low and high, so if we had:
low <-24
high <-48
then we should have this:

hist(runif(1000,0,100),xlab=expression(AUC[24 - 48]~ (xyz)),ylab="Frequency")


appreciate your insights,

Andras
