Counting the occurence of each unique "charecter string"
LS,
I would really like to know how to count the frequency/occurrence of chachters inside a dataset. I am working with extreemly large datasets of forest inventory data with a large variety of different species inside it.
Each row inside the dataframe represents one individual tree and the simplified dataframe looks something like this:
num species dbh
1 sp1

dnorm
...y-values, ys: dnorm function
Problem:
I expected to multiply the ys function with the sample size (n=250-300). I was wondering about a factor between 12'000 and 30'000 to match the size of the dnorm line with the specific histogram.
Thanks
Sibylle
