I am trying to automate an outide of the plot region table that has the correlation coef. of the various variables in the plot. I am currently using bquote to get the greek/latex representation of $\rho$. what I want so what I have is the following
rhoa <- cor(x, data1$No.Msa.Hosp) rhon <- cor(x, data1$N.Not.Profit.msa) rhop <- cor(x, data1$N.Profit.msa)
temp <- bquote(list(rho["Not-profit]==.(rhon),rho["Profit"]==.(rhop), rho["All"]==.(rhoa)))
everything works fine but the problem is that the following legend call legend(par("usr")[2]-a1,3*par("usr")[3]-b1,ex12, ncol=2)
does not respect the ncol argument. I am guessing it is respecting it but bquote is of dimension 1 i.e just a big string. Does anyone know of a way to break this into two columns
There is an example how to work with mathematical annotation in legend() in the Help Desk in R News 2/3.
Please specify easily reproducible examples (not examples with data we do not have) - according to the posting guide!
What you are probably going to do is something like:
plot(1:10)
rhoa <- 1
rhon <- 2
rhop <- 3
exprhoa <- substitute(rho["All"]==.(rhoa), list(rhoa = rhoa))
exprhon <- substitute(rho["Not-profit"]==.(rhon), list(rhon = rhon))
exprhop <- substitute(rho["Profit"]==.(rhop), list(rhop = rhop))
legend(2, 8, do.call("expression", list(exprhon, exprhop, exprhoa)), ncol = 2)
