If layer$z is a matrix and you want to reverse the order of the rows, you can do: n <- nrow(layer$z) layer$z <- layer$z[ n:1, ] HTH, Eric On Tue, Jan 16, 2018 at 8:43 AM, lily li <chocold12 at gmail.com> wrote: > Sorry for the emails, I just wanted to have an example. > layer$z > > 1 1 3 4 6 2 > 2 3 4 1 2 9 > 1 4 5 2 1 8 > > How to convert the matrix to layer$z = c(1, 4, 5, 2, 1, 8, 2, 3, 4, 1, 2, > 9, 1, 1, 3, 4, 6, 2)? > I think this...

...ted to have an example. layer$z 1 1 3 4 6 2 2 3 4 1 2 9 1 4 5 2 1 8 How to convert the matrix to layer$z = c(1, 4, 5, 2, 1, 8, 2, 3, 4, 1, 2, 9, 1, 1, 3, 4, 6, 2)?

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

...how to reformat the colors? Also, how to show the first legend only, but at the bottom, while the second legend in your code is not necessary?

...or.scale to get different colors. With this you can use color.legend to add a mapping of the values and colors. If you just want different colors, say 20, you can do things like: Color_unq<-rainbow(20) Color_unq<-colors(distinct=TRUE)[1:20] Jim On Thu, Jul 13, 2017 at 4:22 PM, lily li <chocold12 at gmail.com> wrote: > Hi Jim, > > How to generate unique (all different) colors for the same dataframe?

...ot; in the past, you should either split your data, estimate on one subset and then test on another, or estimate on your data and test on a replication. If you get pretty much the same values, you can be reasonably confident that they are reliable.
