FIELDimageR: A R package to analyze orthomosaic images from agricultural field trials. This package is a compilation of functions to analyze pos-mosaicking images from research fields, and allows to: crop the image; remove soil effect; build vegetation indices; rotate the image; build the plot shapefile; extract information for each plot; and evaluate stand count, canopy percentage, and plant height.
When I followed EX.P<-rast("EX_Pollen.jpeg") sentence, it showed "Warning message: [rast] unknown extent". Does it mean raster do not support .jpeg? and what should I do if I still want to count the number.
Hi there
When I followed EX.P<-rast("EX_Pollen.jpeg") sentence, it showed "Warning message: [rast] unknown extent". Does it mean raster do not support .jpeg? and what should I do if I still want to count the number.
Thanks
