R: Alinee y centre el texto usando ForeignObject y Sankeynetwork

Creé esta red sankey:

 library(networkD3) library(htmlwidgets) library(data.table) set.seed(1999) links <- data.table( src = rep(0:4, times=c(1,1,2,3,5)), target = sample(1:11, 12, TRUE), value = sample(100, 12) )[src < target, ] # no loops nodes <- data.table(name=LETTERS[1:12]) ## Add text to label txt <- links[, .(total = sum(value)), by=c('target')] nodes[txt$target+1L, name := paste0(name, '<br>(', txt$total, ')')] ## Displays the counts as part of the labels sn <- sankeyNetwork(Links=links, Nodes=nodes, Source='src', Target='target', Value='value', NodeID='name', fontSize=16, nodeWidth=50, width=600, height=300) onRender(sn, ' function(el,x) { d3.selectAll(".node text").remove() d3.selectAll(".node") .append("foreignObject") .attr("width", 100) .attr("height", 50) .html(function(d) { return d.name; }) } ' )

Realmente me gustaría centrar las etiquetas dentro de los cuadros, horizontal y verticalmente, y también alinear las dos líneas en el centro. ¿Me puedes ayudar?
