Here's my working environment, R version 3.4.4/R Studio version 1.0.143, below is the line of code that fails :
brings the error below :
Error in .local(.Object, ...) : Error in .rasterObjectFromFile(x, objecttype = "RasterBrick", ...) : Cannot create a RasterLayer object from this file. (file does not exist)
A previous Q&A (https://stackoverflow.com/q/53237802/820534) is not helpful. I've confirmed that
libtiff5 is installed in the Ubuntu 16.04 box I am using.
