require(PBSmapping)
?convUL
for example ...
points <- data.frame(cbind(data$idnum, data$long, data$lat, data$var))
colnames(points) <- c("EID", "X", "Y", "var")
attr(points, "projection") <- "LL"
## Define as EventData
points <- as.EventData(points)
## Transform to UTM (Euclidean) coordinates, uses package PBSmapping
convUL(points, km=TRUE)
