Hi all, I am using ftable and xtabs to get total counts of species per location per hight category (understory, midstory and overstory). i can save the data in almost the format i would like it to be - but not quite. Here it is an example of what i get: x - is a dataframe with the following columns: LocationID, Species, PercentCover, Category where Category tells if the Species belongs to understory, midstory or overstory y1 <- ftable(xtabs(PercentCover ~ LocationID + Species + Category, data=x))y2 <- format(y1, quote = FALSE, sep = ,)write.table(y2, test1.csv, row.names = FALSE, col.names = FALSE, sep = ,)If i read the test1.csv it will look like that: Category Midstory Overstory Understory LocationID Species Loc1 A 0 0 10 B 10 20 0 C 55 0 10 . Loc2 A 0 0 0 B 5 60 0 C 35 0 25 What i would like: (1) eliminate the column (Category) because it is empty anyway (i suppose i can create a new data.frame from y2 in which i skip column "Category"); (2) have LocationID, Species, Midstory, Overstory, and Understory on the same row; (3) have the column LocationIDfilled in between Loc1 and Loc2 with Loc1 and not an empty string, and so on for each location.Any suggestions will be very greatly appreciated, thanks,Monica
