Converrt a list into frequncy of occurance

[John Pierson]

Hi,
this is a simple problem but i'm sure there must be an icon to cover this.

Say i have a 1D array of numbers for arguements sake lets say:

1,1,2,2,2,2,2,36,59,100,100

how can i convert them into a 2D format that has them in the follwoing format

1,2
2,5
36,1
59,1
100,2

basically a 2D array with the value opposite the data value depicting how many times it occurs??
I've already sorted the array, so all the numbers are next to each otehr already.

Many thanks
John Pierson.

Use the Histogram VI in the Mathematics palette. Here is a demo VI. It assumes positive integers in your list. If the list contains negative values or non-integer values this will not work.

Sorry, should have mentioned i'm running LV 8.2, any chance you could convert it from LV 8.5??
- sorry i can't read it.
Many thanks.

Thank you both very much, i treid to get it converted here in the institution as i know lv 8.5 can *save as* Lv 8.2, but everyone had gone home for the day already!

Hi John,

what do you mean? Iit should be saved for 8.0, so you can open it with 8.2.
