Dear list,

I have two datasets: one is for point samples with lat and long information at accuracy of 0.001 degrees. Another is grid cells at a resolution of 0.0025 degrees. Both datasets are in txt format. Now I need to extract the lat and long information from the grid cell dataset for the point samples by assigning the lat and long of a grid cell to a sample point that falls in the grid cell. I usually get this done in ArcGIS. I was wondering if it is possible in R. I searched but failed to find a right function to implement this in R.

Many thanks for any suggestions.

Regards,
