QUESTION
The greenbrown package does not work with raster time series (RTS) and therefore I wanted to work with raster stack or brick. The trendmap function still does not work in this case with a length problem but both the stack and time function have the same amount of variables. The data is MODIS EVI.
it shows here http://greenbrown.r-forge.r-project.org/trends.php
...trendmap <- TrendRaster(ndvimap, start=c(1982, 1), freq=12, method="AAT", breaks=1, funAnnual=max)
ANSWER
Answered 2019-Nov-13 at 17:59The problem was the size of the data. On a normal machine running the script for the entire study area led to issues but these were resolved by taking a small subset of the data.
