Doesn´t work neither!

I’ve done
coeficientes$b1<-as.numeric(as.character(coeficientes$b1))
And b1 was substituted by NA’s
Then I’ve done
coeficientes$b1<-as.numeric(coeficientes$b1)
And b1 was transformed in other numbers

Thanks anyway,

hi: when I sent you my solution, I didn't realize that
you had factors. if you change the
factors to characters as described in that email, and
then use my approach , i think it should still work.

coeficientes[,(coeficientes[,"b1"] > 0)]
will i think give you all the rows of the object where
b1 is greater than zero.
I can't tell if coeficients is a data frame or a matrix
but the above should work in either case.

I have the following object:

caedois b1 b2 b3
1 1 0,033120395 -20,29478338 -0,274638864

I´ve tried to subset it like this:
coefSelected<-subset(coeficientes,"b1">0)
but it does nothing
Then Ive tried:
coefSelected<-subset(coeficientes,b1>0)
But I´ve got the following
Warning message:
In Ops.factor(b1, 0) : > not meaningful for factors
So Ive tried:
coefSelected<-subset(coeficientes,coeficientes$b1>0)
Warning message:
In Ops.factor(coeficientes$b1, 0) : > not meaningful for
factors
I´ve done
mode(coeficientes)
[1] "list"
But I don´t know how to handle it!
Coul anyone help me?
Thanks,
