[R] problem with arrows( )

[ikuzar]

Hello, 

I have got an issue with this code:

plot(...)
xMontant = as.POSIXlt(ecs$startAt[i]) 
xDescendant = as.POSIXlt(ecs$endAt[i])
arrows(xMontant, 0, xMontant, ecsPOW, col="green")

Here is the error:
"Erreur dans arrows(xMontant, 0, xMontant, ecsPOW, col = "green") : 
  premier argument incorrect"

which means:
" Error in arrows(xMontant, 0, xMontant, ecsPOW, col = "green") : 
first argument is inccorrect"

I have got the same error with segment(...) , usign the same arguments.

Does anybody find where is the problem ?
I checked if xMontant is in the right intervale, so it is. That's OK

thanks for your help
