Subject: [R] [Q] use of expression() in plot() vs. hist()
In plot() I can get greek symbols into text items without trouble.
However, some of the same commands don't work as I would expect with
hist(). See the example below.
> plot(1:10, 2:11, xlab=expression(paste("scaled", rho)))
---- works as expected, ie. prints the greek rho
> hist(c(0,0,0,0,4,5,6,6,6,8), xlab=expression(paste("scaled", rho)))
Error: Object "rho" not found
---- for kicks I tried sigma, it also was not found
Surprisingly the following worked:
> hist(c(0,0,0,0,4,5,6,6,6,8), xlab=expression(paste("scaled", pi)))
---- works as expected, ie. prints the greek pi
Does anyone have any suggestions for how to get such expressions into
hist()?
thanks, Alex
