Calculates the number of valid observations per pixel of a time series RasterBrick.
countObs(x, navalues = c(NA), sensor = NULL, as.perc = FALSE, ...)RasterBrick or RasterStack
Integer. Values representing NA's in time series. Defaults to NA, but multiple values can be supplied (e.g. navalue = c(0, NA))
Logical. Express result as a percentage of nlayers(x)?
Arguments to be passed to mc.calc
A raster layer with the number of valid observations per pixel, either as an absolute value or expressed as a percent of nlayers(x) if is.perc = TRUE.
