[R] bubbleplot for matrix

[Albert Vilella]

Thanks Bogdan for the reply,

I almost got it working, but in my case, the rownames and colnames are
strings, not numbers, and I guess that this is a problem when using your
snippet:

a <-
matrix(sample(1:5,100,replace=TRUE),nrow=10,dimnames=list(1:10,5*1:10))
rownames(a) =
c("aed","fde","fda","yxj","ijk","ddd","gcd","sbe","adc","asd")
colnames(a) =
c("aed","fde","fda","yxj","ijk","ddd","gcd","sbe","adc","asd")
x <- y <- z <- vector()
for (i in 1:nrow(a)) {
  x <- c(x,rep(rownames(a)[i],ncol(a)))
  y <- c(y,colnames(a))
  z <- c(z,a[i,])
}
symbols(as.numeric(x),as.numeric(y),z,inches=0.2,bg="khaki")
text(as.numeric(x),as.numeric(y),labels=z)

> symbols(as.numeric(x),as.numeric(y),z,inches=0.2,bg="khaki")
Error in plot.window(xlim, ylim, log, asp, ...) : 
	need finite 'xlim' values
In addition: Warning messages:
1: NAs introduced by coercion 
2: NAs introduced by coercion 
3: no finite arguments to min; returning Inf 
4: no finite arguments to max; returning -Inf 
5: no finite arguments to min; returning Inf 
6: no finite arguments to max; returning -Inf

Any guess?

Thanks in advance,

    Albert.
