readAreaInfo(fname = "ainfo.txt", id = "id",
                iobs = "iobs", obs = "obs", unc = "unc",
                filenames= "filenames", sep = "\t", 
                debug.level = 1, moreCols = list(NULL)) 

Arguments

fname

name of file with areal information

id

name of column with observation id

iobs

name of column with number of observations

obs

name of column with observations

unc

name of column with possible uncertainty of observation

filenames

name of column with filenames of areas if different names than id should be used.

sep

separator in csv-file

debug.level

used for giving additional output

moreCols

name of other column names the user wants included in ainfo

Details

The function is of particular use when data are not available as shape-files, or when the observations are not part of the shape-files. This function is mainly for compatibility with the former FORTRAN-version. The simplest way to read the data in that case is through readShapePoly in the maptools-package or readOGR in the rgdal-package. See also rtop-package.

Value

SpatialPointDataFrame with information about observations and/or predictionLocations.
