Hello,
I'm Giovanni from ROMA..
I can't find a solution for the error:
"error using packet 1
the y field is not specified and it has not a default value"
(this is my traslation from italian language)
The code is:
pc<- qqmath(~valori,
distribution=function(p) qweibull(p,beta,alpha),
prepanel = prepanel.qqmathline,
panel = function(x, y) {
panel.grid()
panel.qqmathline(y, distribution = function(p)
qweibull(p,beta,alpha))
panel.qqmath(x, y)
},
layout = c( 1,1), aspect = 0.8,
xlab = "Unit Weibull Quantile", ylab = "D"
)
Thanks for your regard,
Giovanni
