scat2scat: Scatterplot driving another scatterplot

Description

A pair of linked scatterplots, where each point the first scatterplot corresponds to a scatter of points in the second scatterplot. The first scatterplot corresponds to a pair of summary measures for a larger dataset.

Usage

scat2scat(scat1data, scat2data, group = NULL, chartOpts = NULL, digits = 5)

Arguments

scat1data

Matrix with two columns; rownames are used as identifiers. Can have an optional third column with categories for coloring points in the first scatterplot (to be used if `group` is not provided).

scat2data

List of matrices each with at least two columns, to be shown in the second scatterplot. The components of the list correspond to the rows in `scat1dat`. An option third column can contain categories. Row names identify individual points.

group

Categories for coloring points in the first scatterplot; length should be the number of rows in `scat1data`.

chartOpts

A list of options for configuring the chart. Each element must be named using the corresponding option.

digits

Round data to this number of significant digits before passing to the chart function. (Use NULL to not round.)

Value

An object of class `htmlwidget` that will intelligently print itself into HTML in a variety of contexts including the R console, within R Markdown documents, and within Shiny output bindings.

# NOT RUN {
# simulate some data
p <- 500
n <- 300
SD <- runif(p, 1, 5)
r <- runif(p, -1, 1)
scat2 <- vector("list", p)
for(i in 1:p)
   scat2[[i]] <- matrix(rnorm(2*n), ncol=2) %*% chol(SD[i]^2*matrix(c(1, r[i], r[i], 1), ncol=2))
scat1 <- cbind(SD=SD, r=r)
# plot it
scat2scat(scat1, scat2)
