Add table (aligned text blocks) to plot in R

legend, plot, r

Solution

If you're really averse to external packages, you can accomplish a version of this in `base` R as well:

plot(1, 1)
v = 1:9
legend(
  'topright', ncol = 4L, title = 'Table',
  legend = c(
    '', 'Row1', 'Row2', 'Row3',
    'Col1', v[1:3], 
    'Col2', v[4:6], 
    'Col3', v[7:9]
  )
)

Caveat coder that since `v` will be coerced to `character`, you'll have to be careful about float formatting (`sprintf` is your friend). There are also other bells & whistles like `text.col` to help spiffen up the plot a bit more if you'd like.

Problem

I'd like to add a small table (for example as a legend) to a plot in R. I think of something like: ``` t <- wantedTableMethod( row("param1", "param2", "param3", "param4") , row(value11, value12, value13, cell(value14, adj=0)) , row(value21, value22, value23, value24) , row(value31, value32, value33, cell(value34, adj=1)) border = F ) plot(1,1) legend("topleft", t) ``` All values of a column should have the same offset. Is something like this possible in R, or do I need to align each value manually?
