Re: [R] add single points to a level plot

Thanks. Now it can run and generate plots, but there are the two lines on each of the plots. I don't know the problem for this? Error using packet 1 any(sp) is not TRUE On Thu, Mar 8, 2018 at 8:48 AM, Eric Berger wrote: > You need to load the package 'rasterVis' > > > library(rasterVis) > > H

Re: [R] add single points to a level plot

library(sos) findFn( "layer" ) findFn( "levelplot" ) Also, experts in spatial analysis tend to answer questions on the special mailing list where the Posting Guide says they should. Read it to find out where that is. -- Sent from my phone. Please excuse my brevity. On March 8, 2018 7:11:34 AM

Re: [R] add single points to a level plot

Hi all, I ran the code: > s <- stack(replicate(2, raster(matrix(runif(100), 10 > xy <- data.frame(coordinates(sampleRandom(s, 10, sp=TRUE)), + z1=runif(10), z2=runif(10)) > levelplot(s, margin=FALSE, at=seq(0, 1, 0.05)) + + layer(sp.points(xy, pch=ifelse(pts$z1 < 0.5, 2, 3),
