Hi R helpers, I tried to convert a list of LatLong coordinates (in DD format) into UTM zone 11 NAD 27. I first tried this from PBSmapping: library(PBSmapping) LatLong<-cbind(c(56.85359, 56.85478),c(-118.4109, -118.4035)) colnames(LatLong)<-c("X","Y") attr(LatLong, "projection") <- "UTM" attr(LatLon...

...the same value on these two columns would not be kept, even if they had different values in other columns). For example, I have a dataframe with 10 columns, two of which are LATITUDE and LONGITUDE. I wish to keep only one row per unique combination of these two columns, so I've tried: unique.latlong<-extracted[unique(paste(extracted$latitude,extracted$longitude)),] but this is returning a dataframe of missing values (NAs). Could anyone point me in the right direction? Thanks! Mark Na [[alternative HTML version deleted]]

Hi there: I am a total beginner in R, and I have a simple question: I have a table with thousands of lines that represent locations, and two columns: latitude and longitude. I need to randomly sample 1000 lines. How do I do it? I know the command "sample", but it samples elements independently, not lines. If there is a better place for me to ask that type of question, please let me
