Yes. Basically, rows/columns get converted to grouping variables with
levels given by the row/column names. E.g.,
> summary(barchart(errs.Means, groups = FALSE))
Call:
barchart.table(x = as.table(x), data = data, groups = FALSE)
Number of observations:
Var2
R Cing Gy R Smar Gy L Inf Fron Gy R Thalamus R Mid Fron Gy
3 3 3 6 6
L Mid Temp Gy L Inf Par\nLbl L Cing Gy R Mid Fron\nGy R Lent Nuc
3 3 3 3 3
R Inf Fron Gy R Mid Temp Gy R Sup Par Lbl R Cere\nTon L Prec
3 3 3 3 3
R Cere Ton L Pyramis R Prec Gy
3 3 3
This is probably slightly different from what you get because line
wrapping has made some names different that were actually the same.
By the way, you are using the 'groups' argument wrong; it can only be
a logical (see ?barchart.matrix).
