entropy function

Entropy

entropy(df, r_vec, markvar)

Arguments

• df: data frame with x and y columns, along with a column for point marks
• r_vec: vector of length wanted for breaks (will be rescaled) with max value at max for measuring entropy
• markvar: The name of the variable that denotes cell type(s) of interest. Character.

Returns

data frame with entropy calculated for length(r_vec) bins within 0 to max(r_vec)
