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?

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.

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$z1 < 0.5, 2, 3), cex=2, col=1), columns=1) + + layer(sp.points(xy, pch=ifelse(pts$z2 < 0.5, 2, 3), cex=2, col=1), columns=2) And got the error: Error in UseMethod("levelplot") : no applicable method for 'levelplot' applied to an object of class "c('RasterStack', 'Raster', 'RasterStackBrick', 'BasicRaster')" what is the problem?

[R] add single points to a level plot
Hi all, I'm trying to add single points with known coordinates to a level plot, but could not find the proper answer. I got to know that layer() function is good for this, but I don't know which package is related to this function. The source is here: https://stackoverflow.com/questions/28597149/add-xy-points-to-raster-map-generated-by-levelplot but my question is a little different as I know the coordinates of the single point, rather than a range. Thanks for any help you could provide.
