hi, i'm tring to plot a streamline my set of data is like this : Vectors: dx dy u v lat lon -6.25000 -2.50000 1.717 -7.092 40.644167 14.092523 -6.25000 -1.25000 1.631 -9.520 40.655418 14.092523 -6.25000 0.00000 1.251 -12.137 40.666667 14.092523 -6.25000 1.25000 0.313 -12.531 40.677914 14.092523 -5.00000 -2.50000 2.789 -4.769 40.644167 14.107351 -5.00000 -1.25000 1.593 -7.360 40.655418 14.107351 -5.00000 0.00000 1.259 -9.956 40.666667 14.107351 -5.00000 1.25000 -0.763 -17.315 40.677914 14.107351 ...... ........ i'm studing a metod for visualize this data any suggestion is more apprechated! thanks Massimo

There is not enough information here to say what you want to know. You have not told us the metrics of the columns (not everyone works in your field), nor how individual streamlines are defined (one row, many rows?). For each group of four rows, dx and lon are fixed and dy replicates.

Hello. How about GrADS(http://grads.iges.org/grads/grads.html) , not R related one, used in meteorology? Formerly it can deal with only gridded data, but currently seems to support station data(irregular spaced data). Regards
