The symbols function can add circles to an existing plot with the diameter
based on another variable. You may need to project points if you draw a map

Dear useRs,
I have two sets of data that I would like to plot in the same window, but their
ranges are really different, e.g.
a <- c(0.2, 0.5, 0.8, 0.3, 0.4, 0.5, 0.2, 0.2, 0.3)
b <- c(100, 2000, 800, 200, 100, 50, 4, 2, 0)
If I do
plot(a, ty='l'); points(b, ty='l')
I won't be able to see sequen

Hi,all!
after executing :

I encountered a error "not-yet-implemented method for %*%

could someone show me some tips?
many hanks!

Try
f <- function(string) as.numeric(strsplit(string, "- ")[[1]])
f(x)
f(y)
f(z)

Is
as.numeric(unlist(strsplit("0 - 13","-")))
what you want?

Hello!
Very often one can hear that MDS usually ends with two-dimensional
solution. Of course, there are methods, like Scree-test (proposed by
Kruskal and Wish, 1981), to determine optimal number of dimensions.
However, I am trying to find references to this two-dimensional
gold-standard. Can
