Overlap function

[Sandra Cuadros]

Hi Chris, I am having an issue when runnin overlap function.

I used the code you provide in help (see below)

library('ctmm')
data('buffalo')

# check if projections are the same
buffalo$Cilla@info$projection == buffalo$Gabs@info$projection

# fit movement models
m1 <- ctmm.select(buffalo$Cilla, ctmm.guess(buffalo$Cilla, interactive = FALSE))
m2 <- ctmm.select(buffalo$Gabs, ctmm.guess(buffalo$Gabs, interactive = FALSE))

overlap(m1, m2)

But it gives me the following error:

Error in overlap(m1, m2) :
  character object class not supported by overlap.

I have installed latest R version and updated ctmm and still don't know why this happens. Any ideas or suggestions?

Hi Sandra — IANC (I’m not Chris) but I think the trouble might be that you’re trying to run overlap() on a movement model, not on a UD. I’m on my phone, not in front of my computer, so I can’t send you any code but check out the ?overlap help file for an example. Hope this helps, Mark

Hi Mark and Chris,

I tried with UD models too, and had no luck. FUrthermore, I am also having issues when loading dplyr in R (4.2.1). I get a message 

error: package or namespace load failed for ‘dplyr’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 there is no package called ‘rlang’

I have tried installing R againg, removing and installing dplyr and rland and still no luck. Any suggestions on why this might be?

Hi Sandra,

Overlap needs to be used on a single list, like in the example, or:

overlap(list(m1=m1,m2=m2))

I will add a more informative error to the function.

I am not familiar with the rlang error. I would check that rlang actually installed without error.

Best,

Chris
