Yes, but you will not like that call. In R (package sp), each spatial data set can only have one single projection. I'd suggest, in pseudo-code
- import the data into a data.frame - for each UTM zone do: select the locations set their CRS reproject to long/lat - cbind the locations to a single data structure - convert back to data.frame if needed. -- Edzer Pebesma Institute for Geoinformatics (ifgi), University of Münster Weseler Straße 253, 48151 Münster, Germany.
