Could somebody give me a pointer on how to generate a SpatialLinesDataFrame from a dataframe, that contains lat,long coordinates as separate variables. At the moment the data looks like this: lat long [1] 53.xxxx 1.xxxx where as the SpatialLinesDataFrame consists of Coordinates [1] (53.xxx, 1.xxx) This is probably a trival issue, but I'm a relatively new user and searching the documentation hasn't yielded and obvious way to do it so far.
