Data format question for triangle.plot package ade4
...evelop 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) &...

variograms and kriging
Hello
Trying to develop variograms and kriged surfaces from a point file. Here is
what I've done so far.
library(gstat) # also loads library(sp)
library(lattice)
soilpts$x <- soilpts$UTM_X
soilpts$y <- soilpts$UTM_Y
soil.dat <- subset(soilpts, select=c(x, y, Area, BulkDensity, LOI, TP, TN,
TC, Total_Mg))
dim(soil.dat)
[1] 1292 7
coordinates(soil.dat) <- ~ x+y
gridded(soil.dat) <- TRUE
