[R] save output of loop

[johnmark]

The short answer to your question is *don't* concatenate the values in the
row, then attempt to /rbind()/ them incrementally to a data.frame.  Instead
build each column separately inside the loop, then /cbind() (data.frame()/ 
does an implicit/ cbind()/ ) them together at the end.  Something like this:

/
lat.column <- c(length(100))
lon.column <- c(length(100))
...
for (i in 1:100){ 
 ...
  lat.column[i]  <- data[,7] # latitude 
  lon.column[i] <- data[,8] # longitude 
   ...
} 
my.data <- data.frame(lat.column, lon.column, ...)
/
