Use expression with a variable r

Question

I am trying to label a plot with the following label:

\"Some Assay EC50 (uM)\" where the \"u\" is a micro symbol.

I currently have:

assay &l         


        

Answer 1

You also could try the poor man's approach:

assay <- "Some Assay"
plot(0, xlab = paste0(assay, " AC50 (µM)"))

It specifies the mu character directly rather than using expressions (and paste0 is just paste with sep = "").
