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)
129239
# 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
Did that "dat" object have what you wanted? The function call did not
make any reference to SoilVegHydro. What does str(dat) return? Oh,
never mind, I now see you use attach.
row.names(dat) <- paste(row.names(SoilVegHydro$Physiogomy),
Generally row.names is used on a dataframe rather than on a column
vector.
> dat <- data.frame(1:3, LETTERS[1:3])
> row.names(dat$X1)
> row.names(dat)
[1] "1" "2" "3"
> length(row.names(dat$X1))
[1] 0
rep(c(1,2,3),
rep(1292, 3)), sep =" ") # following the syntax from the help
triangle.plot page
this is returned when the last line is submitted.
row.names(dat) <- paste(row.names(SoilVegHydro$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
