Description Usage Arguments Value Author(s) See Also Examples

Transfer frequency counts data into abundance data.

1	Count2Abun(count.data)

count.data

input species frequency counts data: a numerical matrix or a data frame of two columns. The first column is the frequency j=1, 2...; and the second column is frequency counts (fj).

Example: there are 59 singletons, 9 doubletons and so on in Insects_data:

[1,]	1	59
[2,]	2	9
[3,]	3	3
[4,]	4	2
[5,]	5	2
[6,]	6	2
[7,]	11	1

a numeric vector of species abundance data.
