I have got an issue with this code:
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"
" 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
