I am trying to plot this raster on R. The object is quite big, but when plotting it using the raster::plot() function, I obtain a very tiny image, as attached.

The code I use to produce it is the following:

r <- raster::raster("MOD13Q1_2000-02-18.250m_16_days_NDVI.tif")
r <- setMinMax(r)

I tried to set xlim limits, with no success. I then tried to move to ggplot2, as an alternative (following here), but I obtain the following

ggplot(r) + geom_tile(aes(fill=value))
Error: ggplot2 doesn't know how to deal with data of class RasterLayer

I found around that, to plot raster objects with ggplot(), I should first convert it into a data.frame. However, as my object is quite big (about 55million obs.), that would be very inefficient. I am then stuck on what to do. Any thoughts?

The base plot method works fine for me:

so I suspect something has gone amiss with your graphics device. If using rstudio, I think there's a little button to reset the graphics window, otherwise try dev.off() to switch the graphics window off, and the next plot will create a new one.

This behaviour generally happens when a previous graphics operation has left the graphics device in a non-default state, such as having divided it up to put a legend in a section of window. A reset as described above usually helps.

There's no need to look to ggplot - the raster package plot methods are very well optimised for big rasters and will sample down large rasters for speed.

  • Thanks for you answer. For some reason it still does not work, and clearly there is a problem with my graphic device. I tried other rasters from tutorials on the web and I am having the same issue. My issue is not with the picture, then, but with some setup on my plotting device. Any thoughts on how to fix that?

  • Edit your question and give some more info on your system, including operating system, R version, raster version etc. If you restart R and do plot(raster::raster(matrix(1:100,10,10))) does it still fail?

In addition to @Spacedman answer... Sometimes, some packages change plot parameters.

You need to set back default parameters and plot again:

r <- raster::raster("MOD13Q1_2000-02-18.250m_16_days_NDVI.tif")

par(mar = c(5.1, 4.1, 4.1, 2.1), mgp = c(3, 1, 0), mfrow = c(1,1), las = 0)


You can also include this into plot function to override an unexpect behaivour:

r <- raster::raster("MOD13Q1_2000-02-18.250m_16_days_NDVI.tif")

plot(r,mar = c(5.1, 4.1, 4.1, 2.1), mgp = c(3, 1, 0), mfrow = c(1,1), las = 0)
  • Thanks for your message. It still does not work. I am facing this problem with other tif files, as well. Any suggestions? Dec 13 '17 at 13:26
  • Are you using RStudio?

  • Yes I am, and indeed I guess that is the problem. I manage to plot it on R, or even running R through the Terminal (I am using a mac). I guess I will open a new question as this one has somehow lost sense... Dec 14 '17 at 9:03
  • I also work with RStudio on macOS. Maybe plot window is too small, try resizing borders

  • Resizing borders did not work at the end. The issue was some changes made by the rts package I installed - I have already contacted its developer. Interestingly, plotting with rastervis::levelplot() works fine. Mar 20 '18 at 17:21
