Dear list members,
I got this error in package "dismo".
fold <- kfold(bradypus, k=5)
> bradytrain <- bradypus[fold != 1, ]
> me <- maxent(predictores, bradytrain)
Error en .readRowsAscii(raster, rows[i], 1) : elemento 1 esta vacio;
la parte de la lista de argumentos '>' ha sido evaluada:
(startcol, 1)
Function maxent works perfect for "bradypus" (data frame with 116
observations), but it doesn't work for "bradytrain" when I use kfold
function.
"bradytrain" is also a data frame but with 93 observations. The message
is in Sapnish, but basically say that element 1 is empty.
Thank you very much in advance.
Best,
Manuel
