Where exactly did you put the sink() statement? I tried it with a 1000
dataframes and I have no problem whatsoever.
Cheers

It is very helpful for me.
I still have a problem with sink stack

Hello I am tryin to use the apply functions with two data frames I've got
and I am getting the following error message
Error en HistRio$SecSte : $ operator is invalid for atomic vectors
I don't understand why. when I use the apply I am doing:
PromP - function(HistRio,AnaQuim){
xx - c(0,0,0)
Hi,
Here is what ?apply says:
Returns a vector or array or list of values obtained by applying a
function to margins of an array.
So apply() works on arrays, not on dataframes! Maybe lapply() would do
what you're looking for (don't have time to look more into it)
And you don't do exactly the
Ivan is -partly- right. However, in the details it says as well that :
If X is not an array but has a dimension attribute, apply attempts to coerce
it to an array via as.matrix if it is two-dimensional (e.g., data frames) or
via as.array.
The main problem is the fact that what goes into the PromP
