[R-sig-Geo] convert long/lati to UTM

[Steve Hong]

Hi R-sig-geo list,

I am very new to spatial stat using R. I have a basic (pretty much to most of you) question. I have data set with "Longitude" and "Latitude" columns and want to convert to them "UTM" Although I found example of it from the previous questions and answers, I am still struggling to handle the task. Can anyone give me step by step guide as detailed as possible? I copied and pasted partial data below.
