[R] Data format question for triangle.plot package ade4

[Steve_Friedman at nps.gov]

hello,

I am trying to develop a triangle plot but am having difficultly assigning
the row.names to the 3 columns in the data.frame

Here is what I've done,

attach(SoilVegHydro)

dim(SoilVegHydro)
1292    39

# now  take 3 variables from main data.frame for plotting

dat <- cbind.data.frame(TP, meanAnnualDepthAve, BulkDensity)  #  These are
variables held in the data frame SoilVegHydro

row.names(dat) <- paste(row.names(SoilVegHydro$Physiogomy), rep(c(1,2,3),
rep(1292, 3)), sep =" ")  # following the syntax from the help
triangle.plot page

this is returned when the last line is submitted.

row.names(dat) <- paste(row.names(SoilVegHydro$Physiogomy), rep(c(1,2,3),
rep(1292,3)), sep="")
Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "1", "1", "1",  :
  invalid 'row.names' length

I'm not certain how to define the row.names .  If anyone can help I'd
appreciate it.

I'm using R 2.11.1 (2010-5-31) on Windows XP

Thanks
Steve
