I am trying to use the levelplot function from a command file.
Here is the code:
library(sp)
library(gstat)
library(lattice)
gatherData <- read.table("~/gather.txt", header = TRUE)
grd = makegrid(gatherData$x, gatherData$y, cell.size = 5)
k <- krige(z~x+y, ~x+y, data = gatherData, newdata = grd, nmax = 5)
levelplot(var1.pred~x+y, k, aspect = mapasp(k), main = "Predicted 5m")
It executes fine (it plots up) when I cut and paste to the command
prompt but it seems to be missed (nothing occurs) when I call the
source file.
I am using OSX.
Thanks for any help.

I think this is an FAQ. Anyway, levelplot() is a lattice plot and therefore must be explicitly printed when source()ed or in a function; i.e. print(levelplot(....)) is required. -- Bert> -----Original Message----- > From: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Matt Sakals > Sent: Tuesday, January 10, 2006 4:00 PM > To: r-help at stat.math.ethz.ch > Subject: [R] Levelplot not working from file > > I am trying to use the levelplot function from a command file. > Here is the code: > > library(sp) > library(gstat) > library(lattice) > > gatherData <- read.table("~/gather.txt", header = TRUE) > grd = makegrid(gatherData$x, gatherData$y, cell.size = 5) > k <- krige(z~x+y, ~x+y, data = gatherData, newdata = grd, nmax = 5) > > levelplot(var1.pred~x+y, k, aspect = mapasp(k), main = "Predicted 5m") > > It executes fine (it plots up) when I cut and paste to the command > prompt but it seems to be missed (nothing occurs) when I call the > source file. > I am using OSX. > Thanks for any help. > Matt > [[alternative text/enriched version deleted]] > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! > http://www.R-project.org/posting-guide.html >
