Steven's solution is great, but it will only work if the rows are really
duplicates. If the data frame contains another variable whose values vary,
it will not work because then the rows are obviously unique.
df<-data.frame(df,value=rnorm(11))
unique(df)
You would then have to make a decision, w
use unique()
df <- data.frame(Species_name=c(rep('Abies concolor',4),rep('Accipiter
cooperi',7)),
Longitude=c(-106.601, -106.493, -106.489, -106.496,
-119.688, -119.792,
-118.797,-77.38333,-77.38333,-75.99153,-75.99153),
Latitude=c(35.868, 35.9682, 35.892, 35.85
