I would like to create a plot of wind directions displayed by arrows for several points. This plot should have no legend and no background since I would like to export it as png and use it as overlay in further workflow. I have an example data fame with 10 points (lon, lat) and wind… Read More Use plot result as an overlay: remove legend and background and export a tiff / png
Suppose I have a the following raster: library(raster) r <- raster(ncols=36, nrows=18) values(r) <- rnorm(ncell(r)) I can discretise its values using cut(): breaks <- -2:2 * 3 rc <- cut(r, breaks=breaks) However, when i try to specify labels e.g., A, B, C, etc rc <- cut(r, breaks=breaks, labels = c("A", "B", "C", "D", "E")) it… Read More specifying labels using cut() on raster
I wonder if there is a way to convert a dataframe to a aster::stack object? my dataste: xy<- structure(list(X = c(-179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75, -179.75), Y = c(-52.25, -51.75, -51.25, -50.75, -50.25, -49.75, -49.25, -48.75, -48.25, -47.75, -47.25, -46.75, -46.25,… Read More How To convert dataframe to raster::stack object?
I am processing a raster image in R with the goal of exporting the processed image as a tiff with the same dimensions as the input data. There are aesthetic processes I need to apply to the data in ggplot (which I won’t go into in this post) which is why I am processing it… Read More Export geom_raster as tiff with specific pixel dimensions/ no ggplot borders
