Re: [R] Fuzzy_partition with fuzzy_trapezoid

[Arthur Stilben]

Thanks, Sarah, for response. But you showed me an example with
fuzzy_variable. I'd like to use fuzzy_partition. I also tried:

> teste = fuzzy_partition(varnames = c('a', 'b'), FUN = fuzzy_trapezoid, 
> corners = c(1,2,3,4), height = c(1,1) )

But the trapezoids 'a' and 'b' were overlap. Is there a way to
construct two separeted trapezoids with fuzzy_partitions?

[R] Fuzzy_partition with fuzzy_trapezoid

I already made this question, but I was not subscribed and not
received any reply. I tried this:

But I got this error:

Error in FUN(i, ...) :
  formal argument "corners" represents multiples specified arguments

Is it possible to combine fuzzy_partition with fuzzy_trapezoid?

Att,

Thanks, Sarah, for the reply. It really works.

 As Jeff suggested, I read the help for you.

 Based on the examples, you need:


   ## set universe
   sets_options("universe", seq(from = 0, to = 10, by = 0.1))
   teste2 = fuzzy_variable( a = fuzzy_trapezoid( corners = c( 0, 1, 2,
 3 ) ) )

 comparing
 plot(teste) # complete with Warning
 and
 plot(teste2)
 makes me think this did what you wanted. At least, it did something.

[R] Fuzzy variable universe

[Arthur Stilben]

Hello, everyone!

Is there a way to set universe group for each fuzzy_variable? I try to do this:

> teste = fuzzy_variable( a = fuzzy_trapezoid( corners = c( 0, 1, 2, 3 ) ), 
> universe = seq( from = 0, to= 10, by = 0.1 ) )


But when I print teste:

> teste
A fuzzy variable with values: a, universe


So, how can I set universe on fuzzy_variable?

[R] How to use fuzzy_partition with fuzzy_trapezoid

[Arthur Stilben]

Hello, guys!

I tried to do that:

> teste = fuzzy_partition( varnames = c( "a", "b" ), FUN = fuzzy_trapezoid, 
> corners = c( 0, 1, 2, 3), corners = c(4, 5, 6, 7))
Error in FUN(i, ...) :
  argumento formal "corners" corresponde a múltiplos argumentos especificados


So, how can I use fuzzy_partitions to generate multiples trapezoids?
