Year	year
Age	age
and	Catch
catch (thousands of individuals)	or
Resid	standardized residual

bubbleplot is an effective way to visualize these data.

Examples

catch.t <- xtabs(Catch~Year+Age, catch.d)
catch.m <- as.matrix(as.data.frame(unclass(catch.t)))

# 1  Formula
bubbleplot(Catch~Age+Year, data=catch.d)
# Use rev=TRUE to get same layout as crosstab matrix:
print(catch.m)
bubbleplot(Catch~Age+Year, data=catch.d, rev=TRUE, las=1)

# 2  Data frame
bubbleplot(catch.d)

# 3  Matrix or table
bubbleplot(catch.m)
bubbleplot(catch.t)

# 4  Positive and negative values
bubbleplot(catch.r)
bubbleplot(Resid~Age+Year, catch.r, subset=Age %in% 4:9,
           rev=TRUE, xlim=c(3.5,9.5), cex=1.3)
