Hello R Users, I am trying to use math expressions as the labels to dotplot. I have a vector of string values, for example: names<-c(x1^2, x2^2)
This won't work: names <- c(x1^2, x2^2) Error: Object "x1" not found 1. You can set "x1^2" in quotes, to make this assignment work. 2. It is a bad idea to call the vector "names", because it's already a function. What you could better do is: my.names <- expression(x[1]^2, x[2]^2) dotplot(1:2, labels = my.names)
I am trying to do something like this: dotplot(c(1,2), labels=expression(names)) I had hoped that expression(names) would return a vector of math expressions which could be used as the labels. It doesn't. Is there any way to do this??
