Calculates the frequency of an obervation in a 2D cell

freq(x, y, x.n = 11, y.n = x.n, na.rm = FALSE)

Arguments

x

a vector holding a time series

y

a vector holding a time series

x.n

a numeric vector giving number of bins

y.n

a numeric vector giving number of bins

na.rm

logical; if true, any NA and NaN's are removed from x before calculations

Value

a data.frame frequency by bin

Examples

# NOT RUN {
   y=rnorm(20)
   x=rnorm(20)
   freq(x,y)
# }
