coo_smooth problem

[alejandraalvarezUU]

Hi!

I was trying to remove digitization noise from my data using the command

coo_smooth(data$coo, n)

But is not working, the error that it gives is:

Error in coo_check.default(coo) : do not know how to turn into a coo

I don´t understand why saying that.

Thank you for the help, have a lovely day,

Alejandra.

Hi Alejandra,

if "data" is an Out (or more largely a Coo object), then coo_smooth(data, your_n) would help. Otherwise, try it on a single outline, say coo_smooth(data$coo[[1]], 5)

hope this helps,

Hi!

So it did work, but I don´t understand this part of the code "coo[[1]], 5", so I know it is the coordinate for one of my organisms but which? And does this means that I have to do this for each of my samples? This is my first time using R, so I am not very acquainted with it yet.

this means, "acces the 1st outline in $coo (a list component) and do 5 smoothing iteration. See ?coo_smooth for help

so I know it is the coordinate for one of my organisms but which? And does this means that I have to do this for each of my samples?

of course not ;-) that's why you would use coo_smooth(your_Out, number_of_smoothing_iterations) -- see ?coo_smooth

This is my first time using R, so I am not very acquainted with it yet.

that's alright, we have all been there ! have a look to the tutorial : https://github.com/MomX/Momocs/releases/download/v1.4.0/Momocs_intro.html

Thank you for the help, have a lovely day,

Hi

in your opinion, which is the best number of iterations that can be used or how can I define this?

Thank you, have a lovely day,

Alejandra.

I d Say none ! Juste calibrate tour harmonica retour to sth reasonable Say 95% and et will handle digitization noise anyway ;)
